Reese Fifth Wheel King Pin - RP77FR

  • Lippert 0115
  • Lippert 1116
  • Lippert 1716
  • 20000 lbs GTW
  • Upgraded Pin Box
  • Reese
  • Provides Turning Clearance
  • Rotating Turret

Make tight 90-degree turns with your short-bed pickup while towing your fifth-wheel trailer using this extended pin box. The pivoting action lets your trailer turn and clear the cab so you don't have to exit your truck to adjust when turning.


Features:

  • 5th-Wheel pin box lets you make tight turns while towing your trailer, even in your short-bed pickup
    • No need to get out of your truck to adjust a 5th-wheel slider
  • Rotating turret acts as new pivot point, letting you clear your truck's cab while turning
    • Pivot point is moved 22" towards the rear, offering plenty of clearance while still keeping your load safely in front of the rear axle
  • Easy hookup and disconnect - king pin slides into your 5th-wheel trailer hitch from almost any angle
  • Locking wedge prevents king pin from rotating inside your Reese or Pro Series 5th-wheel hitch
    • Some other 5th-wheel hitches may require custom wedge (sold separately)
  • Simple to maintain - just lubricate king pin, screw, and pivoting shaft
  • Bolt-on installation - replaces your existing 5th-wheel pin box
    • A 1-1/8" socket and wrench are needed for proper installation


Specs:

  • Designed to replace the following pin boxes:
    • Lippert 0115, 1116, and 1716 models
    • Fabex 500 Series and 700 Series
    • RBW 7019 and 70208 models
  • Weight capacity: 20,000 lbs
  • Maximum pin weight: 5,000 lbs
  • Clearance: see formula below to ensure proper clearance
  • Limited lifetime warranty


Clearance Formula

Use the formula below to ensure that there will be enough space between your truck cab and trailer when you are executing a 90-degree turn with the Sidewinder installed.


(A + B) - C = Clearance

A = Distance from center of fifth-wheel hitch jaw to truck cab in inches

B = Length of Sidewinder arm in inches (22")

C = Width of trailer in inches divided by 2


For example:

If you are using the 20,000-lb Sidewinder, then B = 22"

If the distance from the center of your hitch to your truck's cab is 36", then A = 36"

And if your fifth-wheel trailer is 102" wide, then C = 51"

102/2 = 51

Therefore,

(36 + 22) - 51 = 7" of clearance


The Sidewinder Design

Sidewinder Diagram
  1. The pivot point sits 22" behind the king pin.
  2. The rotating turret attaches to the pin box on your trailer to provide the new pivot point.
  3. The reversible, adjustable king pin locking wedge (not pictured) prevents pivot at the fifth-wheel hitch.
  4. The king pin connects to the fifth-wheel trailer hitch in your truck bed.
  5. The arm is rated at 20,000 lbs.


Get Up to 90-Degree Turning

90 Degree Turns with Sidewinder

It is now possible to turn your short-bed truck 90 degrees without having to worry that your trailer will collide with the cab of your truck. The universal king pin locking wedge included with this Sidewinder prevents your trailer from turning or pivoting at the fifth-wheel hitch. Instead, the rotating turret at the end of the Sidewinder allows turning and pivoting to take place an additional 22" away from the cab.



Custom King Pin Locking Wedges: The included universal wedge prevents the king pin from rotating in most fifth-wheel trailer hitches. Certain hitches, however, require a custom wedge (sold separately).


Note: Do not use the Sidewinder with any of the following:

  • Curt Q Series fifth-wheel trailer hitches
  • PullRite SuperGlide fifth-wheel trailer hitch
  • Reese Trail Boss fifth-wheel trailer hitch
  • B&W Companion fifth-wheel trailer hitches that mount in the Turnoverball gooseneck hole
  • Colibert 208BW fifth-wheel trailer hitch
  • Hi-Rise gooseneck-to-fifth-wheel adapter by Draw-Tite, Hidden Hitch, Bulldog and Reese
  • Any other gooseneck-to-fifth-wheel adapter

Parts where on back order per information given by my 2 other vendors etrailer had it in stock and arrived on time before original ETA
As a owner of a small business etrailer is great to work with and always helpful.



by:

I'm an absolute green horn, jumping in big time with a 45' Momentum and desired RAM 3500 HO Mega cab. After extensive research, I was glad to find validation here for an "ultimate short bed solution" with the Sidewinder cushioned on a BD5 Trailer.
My only other consideration at this point would be the Reese goose ball.
It may not offer quite as much turning angle or cushioning, but has the bed space advantage. Thank you!



by:

Sidewinder worked great for my short bed Ram. Be sure to get the matching wedge for your hitch.

Thanks etrailer. I will be using you for all my trailer components



by:

I am using this pinbox with a 6.6' bed on my Ram with Ramboxes. My old pinbox would hit the sides and limit my turning ability. This was an awesome solution, very happy.

Had a 16k sidewinder inbox it cracked traded it out for a20k w/o air bag much beefier unit etrailer helped me out to warranty the pinbox with out a problem Reese drug me along for 3months with no results.
But Paula T. got me taken care
Side note I don’t think it’s right to have to pay freight to return a faulty part that is not my fault. Just wrong. If it was my fault that would be ok. etrailer should change there policy on this !!!!



by:

My only regret with this kingpin is not switching to it sooner. I recently changed up my entire set up to this kingpin and a Hensley BD5 Trailer Saver hitch, for my 41ft Jayco Seismic Wave. If you use a slider hitch, whether auto or manual, you know there's a significant lag in response from the trailer when turning and backing. This kingpin eliminates that lag time. My hitch/kingpin combo is a pricey upgrade, but if you tow often then it will be money we'll spent.



by:

I needed the sidewinder hitch due to transferring from a standard bed truck to a short bed. I installed it my self and the setup was very easy. It works just as it should!



by:

I really like this. Simplifies the dump for sure.

E trailer and camco sewer
hose support system is excellent

Great customer service and quick shipping.

I drive a RAM 2500 shortbox diesel with the Rambox feature that I really like. It also had the factory puck system in the bed. But when I found the 5th wheel I wanted i soon realized that the stock Lippert pin box would not work with my truck. I wanted to use the Curt A20 hitch that I already had but assumed that I would need to replace that for a sliding hitch. When I discussed my issues with the etrailer support tech he told me about this Reese sidewinder and all the reasons it would work with my truck where nothing else would. He was spot on with his advice. I've now had the Reese for a year and have been out many times without issue. I can even make 90° turns and the trailer cap doesn't even come close to the truck cab. I can even open the Rambox most of the way with the trailer mounted. I'm very happy with the product. This hitching stuff can be complicated and risky and I'm glad I talked to the support team before I may have made a stupid mistake.



by:

Excellent product! Took seconds to set up and worked prefect! Unfolds easy , nice carring handle. I would highly recommend this. Price and shipping is great.



by:

I don't always need a hose support system but when I do I use this. Yes it's light plastic so careful. Used about 4 times and nothing has broken.



by:

When we ordered the Yakima Sidewinder, we hadn't realized that the luggage rack on our new RAV4 was a newer style that did not fit the couplings included with the Sidewinder. We spoke with a rep at Yakima who helped us find a fix (a set of couplings that worked) and discounted the price to us. We have a tandem bike that is quite heavy. This product makes it possible for us get the bike on the top of the car (my wife has a bad back, so I need to do most of the heavy lifting myself) and go anywhere. The product feels good and solid, too. We're secure using it and driving all over the cities and rural areas near Minneapolis.



by:

Nice to be able to stretch it out a long way if you need it to.



by:

I purchased this just over one year ago and it has performed its mission flawlessly. I have moved my tandem multiple times and thousands of miles on a 2005 Chevrolet Uplander LT without incident. The bike is held securely at the front fork and the bottom (horizontal) tube between the bottom brackets. I was concerned initially, but this does hold the bike very securely. In my opinion, the biggest benefit of this design is the incredible ease of loading the bike. The front pivoting feature makes loading a tandem easier than loading any other bicycle on any other rack I have ever used. I can do it alone and my feet only need to leave the ground to attach the bottom tube restraints, much less than what I need to do when loading single bikes.



by:

Needed a pin that would fit my short bed and Ram Boxes. After extensive research I coupled this along with the B&W patriot 18K hitch and I have full clearance on my trailer and cab. I now have an extra 22 inches that other hitches wouldn't and couldn't give me.



by:

it works great we used boards before purchasing the camco sidewinder RV sewer hose support system with storage handle.



by:

Having a Ram 3500 Megacab, short bed, I was terribly worried about hitting the cab with my Momentum toy hauler given it's 102" wide. My choice was slider or this Reese Sidewinder. I chose the Sidewinder and darn glad I did. It works as advertised and I can turn a full 90 degrees with about 5" of clearance between the cab and my front nose of the trailer. Some words of caution: this pin box is heavy! Get it professionally installed by your RV dealer. The wedges for your particular hitch will take some getting used too. Move wedge back to hitch, move forward to lock into place. Even still, I need to lay in the bed and have rigged up a heavy wire to assisting getting that wedge tight in the funnel. If you don't, the hitch will move on corners and you feel a big shift of weight.

Bottom line, I like it, it was the right decision for me and didn't take up any more payload than necessary unlike a heavy slider hitch. Recommended! And etrailer delivered on time as promised.



by:

Excellent delivery and great pricing



by:

For those who are considering a “slide hitch” this is a better alternative. Rather than get into a bind and need to release the slide feature, the Sidewinder pin box pivots farther back than a typical pin box so it never puts your pickup in a compromising position. I purchased a 20k standard hitch to use in conjunction with the Sidewinder. I have no regrets and I highly recommend this pin box.



by:

It is the best thing that a novice 5th wheel owner could ask for. Having to go get a class A license to pull my trailer, it made it easy for me to pass the test with litte 5th wheel experience but a lot of bumper tow experience. The mechanical aspect of this unit is what sold me. Few moving parts and no sliding components made me feel safe and confident while navigating my trailer in some difficult situations. And pulling a 19,000 pound trailer accross California's raods, you need all the confidence in your equipment you can get.

  • Is The Reese Sidewinder Compatible With Curt A16 5th Wheel Hitch
    Unfortunately, the Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP77FR you reference is not compatible with Lippert Rhinos.

  • Should a Brand New Sidewinder Be able to be Turned by Hand
    When a Sidewinder like part # RP77FR is brand new you are not going to be able to turn it by hand. I have had the joy of assembling these before and they are just way too tight at first to turn by hand. After a few miles you should find that the arm will turn by hand with enough pressure.

  • Recommended Replacement For A 1116 Pin Box In A 2022 Ford F-350 SRW Short Bed
    There isn't enough of a length difference between 1116 pin boxes to fully accommodate your 2022 Ford F-350 SRW short bed. Instead you can replace the pin box with the Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP77FR which would push the pivoting point back 22" to increase your turning clearance. This type of pin box will require a wedge kit which is specific to the 5th wheel hitch you'll be attaching to. The wedge kit will lock the king pin in place allowing the trailer...

  • Replacement Sidewinder 5th Wheel Pin Box to Replace Lippert 1116 Pin Box
    For your Lippert 1116 original pin box we do offer an option, the Reese # RP77FR sidewinder. This Sidewinder replacement will extend your turning clearance by shifting the trailer's pivot point rearward by 22-inches. All sidewinders include a universal wedge to lock your king pin so that the trailer pivots at the Sidewinder. Certain hitches may require a custom wedge. Note also that certain brands of 5th wheel hitch, including B&W, cannot be used with certain Sidewinders. This is noted...

    A lot of play or little play in your Reese Sidewinder # RP77FR can be subjective to the observer. Either way, if there is enough movement to cause you concern, as it apparently does, then that is enough reason to investigate. Please examine all bolts and connecting points for fitment and consider taking to an RV shop for a look over if you do not find anything but still have concerns. Verify that you are using the correct wedge for your Sidewinder and 5th Wheel Hitch. To tell you that...

  • Pin Box Replacement Solution for 1716 that will Stop Tonneau Cover Rail Interference
    Since in your pictures it looks like the pin box is hitting the sides of the tonneau cover rails when you turn your best pin box replacement solution will be a Sidewinder with the part # RP77FR to replace your 1716. What this will do is move your pivot point up higher by a significant amount which will then allow the truck to turn without the interference. This also will allow your trailer to track better behind your truck and will make it easier to back up. You would not be able to replace...

  • Recommended Sidewinder to Replace LCI 1116 Pin Box
    To ensure that the pin box that is replacing your LCI 1116 pin box is the correct replacement you will need to stick with the same 1116 numbers as they are specific. I believe you are wanting to change it out to a Sidewinder that replaces the 1116 pin boxes (some of them do fit both 1116 and 1716 pin boxes). Since the GVWR of your trailer is over 16,000 lbs I recommend going with the Sidewinder part # RP77FR as a replacement. This is rated for 20,000 lbs and will give you an additional...

  • Is a Spacer kit Needed for Sidewinder to Replace Lippert 1716 Pin Box
    You do not need to purchase a spacer kit separately to use a Sidewinder when replacing your Lippert 1716 pin box. Reason for that is the spacer kit already comes with the Sidewinder. So all you need to purchase to replace your Lippert 1716 pin box is the following: - Reese Sidewinder 5th Wheel King Pin with Rotating Turret - Lippert 1716 and 0115 - 20,000 lbs # RP77FR

  • Option to Replace Lippert 1116 Pin Box For Turning Clearance
    There isn't anything longer so if you want to improve your turning clearance, what you'll need is a Sidewinder to replace your Lippert 111 pin box, with the correct fit being the following: - Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP77FR This will move the pivot point backwards 22 inches which gives you the needed clearance so your trailer doesn't smash into your truck window.

  • Sidewinder That Will Replace Lippert 1116 Pin Box on Fuzion Toy Hauler
    Thanks for that information and based on that I can tell you exactly what you need. I reached out to Lippert with your pin box serial number and they told me that your 2015 Keystone Fuzion 325 pin box is a Lippert 1116 model. The correct replacement for a Lippert 1116 is the Sidewinder # RP77FR. You have made a really good choice because this pin box is going to give you the comfort of never having to use a sliding hitch.

  • Recommended Hitch Weight Class For A Keystone Montana HM130RE
    No, a 15,000lb rated fifth wheel hitch would not be enough for a 14,500lb trailer. Not only is that just too close without even packing your stuff in it, but also manufacturers recommend only utilizing 80-85% of the total weight capacity of your hitch and pin box for safety. At that size you'll need either an 18k or 20k rated fifth wheel hitch and pin box. Pin Boxes are bolt pattern specific so you would need to find out what kind of pin box is on the Keystone Montana HM130RE to know...

  • Should The Sidewinder Wedge Rotary Wheel Still Rotate While The Wedge Is Torqued Down
    The rotary wheel on your Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP77FR should still be loose enough to slide your wedge back and forth while it's torqued down. It sounds to me like you may have accidently over-torqued the bolts so I recommend checking the manual that came with your Sidewinder and ensuring that you're torqueing the bolts to the correct specifications.

    There are not any videos that we have removing the turret from the pin box on your Reese Sidewinder 5th Wheel King Pin with Rotating Turret # RP77FR, however all you are going to need to do is remove the 4 bolts shown in the attached image. Once lubricated, you'll just want to put the bolts back and ensure they are torqued back to 150-ft-lbs initially, then back off the fasteners and re-torque the 4 bolts to 45-ft-lbs.

  • Pin Box Replacement Solution for Lippert 1116 that Can Give Additional Turning Clearance
    If you need additional turning clearance what you would want is a Sidewinder pin box like the part # RP77FR which fits in place of the 1116 pin box that you have now. This would give you quite a bit more turning clearance at 22-1/2 inches since the pivot point is moved back that far. There isn't a standard style pin box replacement that would give you just a little more clearance as the replacements are designed to have the same dimensions as close as possible.

I looked up your current pin box with the LCI Number you provided and you have a Lippert 1116 19k so to switch to a sidewinder the compatible fit is the Reese Sidewinder 5th Wheel King Pin with Rotating Turret - Lippert 1716 - 20,000 lbs Item # RP77FR.

  • How to Lock Out Reese Sidewinder Pin Box for a Long Truck Bed
    Yes, to lock out your Reese Sidewinder, like part # RP77FR, for use with a long bed truck you just need to remove the wedge and then install the bolts at the back end of the pin box to prevent it from rotating (see attached). This is the same case for all Sidewinder pin boxes. Once this is done the pin box will stay in a fixed position and will rotate at the king pin as opposed to the turret.
