Sidewinder Options to Replace a Lippert 1621 Pin Box

Question

Question:

Im considering replacing my Lippert 1621 pin box with a side winder turret and pin box. I see so many part numbers offered what would be the correct numbers? Can you provide a list of Sidewinder numbers and fitments? Thanks

There are two options for Sidewinders to replace a Lippert 1621 pin box. For a 16k rated Sidewinder we have the part # RP61422. If you need more capacity than that you would want the 19k version which is part # RP34FR.

The first option listed above is an air-ride, cushioned Sidewinder that will offer a much smoother ride with its fully enclosed, custom-tuned air spring in air ride trailer coupler that cushions and absorbs shock.

To replace the 1621HD pin box on your trailer, the Reese Sidewinder # RP61421 will work perfectly. It has the capacity needed for this trailer size and will do a great job of providing all the turning clearance you need.

The only way to determine what your pin box's bolt pattern is would be to either get the serial number/RPO number off the tag on the pin box or to use the attached guide below to measure the bolts and crossover those measurements on the included…

That is a good question and the answer is still that it is best to have 6 inches of clearance all the way around, including from the tailgate to the king pin box. I appreciate the photo you sent as that makes it clear how little room you really have.…

The best option for increasing the gap between your truck side rails and the Forest River Flagstaff Classic Fifth Wheel overhang may be to simply replace your PullRite hitch with a taller fifth wheel hitch. Based on my research, it does not appear…

Since your Ford F-250 is a 6-3/4-foot short bed and your Grand Design Reflection 29RS 5th wheel does not have a tapered nose for increased turning clearance you will need a slider hitch to be able to safely make tight turns, or you can install a…

We have some ways to gain more clearance in your truck bed but you'll need to either use a sliding hitch like the B&W Patriot #BWRVK3270 (you would just need the base #BWRVB3270) or you need to use a Sidewinder pin box which has a rotating…

I do have some potential solutions for you but there isn't a safe way to extend a 5th wheel trailer pin box. An extension would add additional stress to the trailer frame leading to damage or failure. In order to move the pivot point of a trailer…

It is not really a fair comparison between Reese hitch #RP30047 and Curt hitch #C16115. The Reese hitch is absolutely better. That hitch in particular has been around a long time. If chucking is a concern you definitely want to avoid hitches that…

You will not be able to use a lift kit since your axles are already under the springs. Your only option is to go with taller hangers. You will have to measure the height of your existing hangers and use the weblink I will be including below to find…

Yes, the 1116 and 1716 bolt patterns are the same, with the only difference being the length of the pin boxes. We currently only offer the 1716 as a standard pin box, like part #LC1191201.

Answer 11

The trailer lift kit options really come down to the axle type and setup. For leaf spring axles, you can either flip the axles with a kit like part #K71-384-00 or part #K71-385-00 or you can raise the hangers/shackles with a kit like part #LC425750.…

Answer 12

Increasing the tire and wheel size can increase the height of the trailer but it's usually quite minimal. Before you do anything else you should see if the pin box can be adjusted. Although you have to be careful here since This will lower the…
