Pin Box Upgrade for 2017 Bighorn 3760EL For Additional Turning Clearance and Chucking Reduction
Question:
I have a 2017 Bighorn 3760EL. I am looking to replace the pin box. I want something that is extended and reduces chucking . Looking for choices. I saw the Trailair and the 5th Airborne. What others are there? Thanks,

From the research we have done on the Bighorn 3760EL you would have a Lippert 1621 pin box from the factory on the trailer. You still will want to verify this by looking at the pin box and finding the numbers 1621 and Lippert on it. That means that for a pin box that is cushioned that will also give turning clearance you would want the Sidewinder 5th Airborne Part # RP61422.
The Sidewinder portion of this pin box allows you additional turning clearance by moving the pivot point of the box back 22 inches and the 5th Airborne reduces the chucking.
