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:
    • Fabex 663 and 665
    • Lippert 0719, 1621 and 1621HD
    • M&M 663 and 665
    • Lippert 1716 and 0115 (spacer kit required - sold separately)
    • Lippert Rhino
  • 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
  • Curt A-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

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.

Its been a year since I upgraded my hitchkingpin set up and my feelings are still exactly the same. The kingpin is great. I love how much faster the trailer responds, especially when backing up, compared to my old slider hitch. Definitely money well 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 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:

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:

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:

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.



by:

Got expert advice from David B. This arrived along with my Reese fifth wheel hitch and they work beautifully together to solve my problems with towing a fifth wheel with a ram that had a ram box. Giant pain in the butt but problem has been resolved thanks to y’all



by:

The sidewinder works exactly as advertised, We installed this on our 41' Heartland Landmark 365 and the increase in manuverability is awesome.
The quality is top notch and I would recommend this product all day long.
I installed this myself and it bolted right into place with zero issues.
If your on the fence about purchasing this product I highly recommend pulling the trigger, you won't regret it...

It works great on my 5th wheel 40 ft toy hauler momentum

  • Correct Reese Sidewinder Replacement for Lippert 1621 OEM Pin Box
    The SW16K you referenced is a product that is no longer available. It's the Sidewinder minus the air ride component. The # RP34FR (Reese part number 68220) has a 16K capacity, and would be a direct bolt-on replacement for your existing Lippert 1621 pin box. I've linked to a product description video featuring the # RP34FR.

    You will be safe towing your trailer with your 2015 Ram 2500 as long as you are under the 20,000 when using a Sidewinder rated for 20,000 lbs. You will not need to remove your truck tailgate to use a sidewinder. For your 20,000 lb options the pivot point sits 22" behind the king pin and above your bed rails and tailgate. The rotating turret attaches to the pin box on your trailer to provide the new pivot point since the king pin is locked in place at the hitch. Your best option if...

  • Is Sidewinder Needed to Tow Fifth Wheel Trailer With 2010 Toyota Tundra Crew Max With 5.5 Foot Bed
    Since the truck bed is less than 6 feet on your 2010 Toyota Tundra Crew Max 5.5 foot bed, you will need to use a standard fixed fifth wheel hitch and a Sidewinder to give you the necessary clearance between your vehicle and trailer.

  • Locating Reese Sidewinder Pin Box for Aerolite 5th Wheel Trailer
    Reese Sidewinder pin boxes are designed to replace the factory pin box model on your trailer but trailer manufacturers don't often provide this type of information.

  • How To Pick Out Sidewinder Pin Box for Fifth Wheel Trailer
    Sidewinders are pin box specific so you will first need to know what pin box you have now in order to pick out the correct one. There should be a sticker or a stamping on the OEM pin box of the trailer that will list the pin box number that is on the trailer. Once you figure out which pin box you have you can check the FAQ I attached that has a chart that shows the correct Sidewinder to get based on which pin box you have.

  • Do Long Bed Trucks Benefit from Reese Revolution/Sidewinder Pin Boxes
    Sounds like your trailer has a Reese Revolution pin box on it. These pin boxes are especially great for short bed trucks but also have advantages for long bed trucks too. The trailer will track better behind your truck and will be easier to back up since the pivot point is moved back 22 inches. I would recommend you allow it to pivot. The lock out bolts would need to get torqued to 275 ft lbs though. I attached a help article on Reese Revolution/Sidewinder pin boxes as well.

  • Is There An Easy Way To Determine If I Have A Gen 1 or Gen 2 Sidewinder Pin Box
    This is a great question and there actually is a really quick and easy way to tell if you have the current (Gen 2) version of the Reese Sidewinder like # RP34FR or an older Gen 1 design. All you have to do is look at the pin box itself and find the Reese brand decal on the unit. The older versions all have square or rectangular decals while the current generation uses a circular decal. I have attached a picture of the current Gen 2 unit below so you can see the round decal used.

  • Where to Get Lock Out Bolts for a Reese Sidewinder Pin Box
    We don't sell the 3/4 x 5-1/2 inch grade 5 bolts needed to lock out a Sidewinder. The only way you will be able to get the correct bolts would be to go to your local hardware store and get them there. This will save you time as you won't have to wait for the bolts to get shipped as they will be readily available at your local hardware store. Take a look at the instructions I have linked on page 6 for more on the lock out feature.

  • Can a Sidewinder be Used with a PullRite Superglide Hitch on a 1999 Alfa Ideal 5th Wheel Trailer
    If you need to know the pin box on the trailer to determine if there is a Sidewinder that will fit I have to tell you that Sidewinders cannot be used with the Pullrite Superglide hitch. This is because the Superglide slides automatically and that travel, coupled with the 22 inch extension of a Sidewinder, creates a dangerous situation and could damage the hitch, trailer, or truck. If you need to know the pin box to use a capture plate and will not be using a Sidewinder then take a look...

  • Sidewinder Pin Box for Use With Reese 5th Wheel Hitch in 2012 Toyota Tundra Crew Max 5-1/2ft Bed
    Usually with short bed trucks you have the option of a slider or Sidewinder, but considering you have a 5-1/2 foot bed I think your best bet to safely tow your Triumph 5th Wheel is going to be with a Sidewinder pin box like the Reese # RP34FR. A Sidewinder style pin box like the Reese is going to provide you with 22" of travel compared to a sliding hitch, that typically can give you anywhere from 8-14". This extra clearance is going to compensate for the shorter bed on your 2012 Toyota...

  • Can Sidewinder Pin Box Adapter be Converted to Gooseneck Hitch Ball
    You can not adapt a Sidewinder to a gooseneck ball since it's a pivoting pin box style that just can't work with a ball since the Sidewinder needs something it can lock out against like a fifth wheel hitch head and jaw. Now if you can get me the Sidewinder part number you have I can see if there's a gooseneck adapter replacement for it like a Reese Goose Box part # RP34FR which fits in place of the very common Lippert 1621 pin box.

  • Can Ram Truck with Ram Box Bed Rails Tow Fifth Wheel Trailer
    The problem with the Ram Box is that is that it puts the rails of the bed too close together and it causes interference with the pin box of the trailer around corners. We have heard several customers say that with a Sidewinder pin box they were able to tow a fifth wheel trailer with a truck with a Ram Box. Sidewinders move the pivot point higher so the Ram Box wouldn't interfere. The only problem is that Sidewinder hasn't officially said that you can use a Sidewinder with a truck with...

    I understand that the current setup is not allowing you enough clearance when making turns while towing your fifth wheel trailer with a 2010 Toyota Tundra 5.5 ft bed. My suggestion would be to replace your current pin box with a Sidewinder. The big difference between a standard pin box and the Sidewinder is the location of the pivot point. When using a Sidewinder, the location of the trailer, in relation to the truck, is not altered. The Sidewinder still attaches to the hitch at the king...

But my understanding is that the installation and operation of the pin box is the same regardless of bed length.
