Because it's lighter, less expensive, has fewer moving parts and is mechanically less complicated I'd recommend going with the Gen-Y #325-GH-8040 shock absorbing pin box versus a Trailair Flex Air like part #LC328492. The Trailair features a…

The Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1621 or 1621HD - 18,000 lbs #LC328330 does require capture plates for the Demco Hijacker autoslide that is similar to the Pull Rite Autoslide you have. The measurement from the front of the plate to…

Most standard pin boxes will not make a 90 degree turn in anything less than an 8 foot truck bed, but that is due to being too close to the cab - not the rails. You mentioned you wanted to replace the Rota-Flex with the Gen-Y hitch. Your old pin box…

Yes, a Gen-Y pin box, like part #325-GH-8040 you're looking at, is compatible with the Demco Hijacker Autoslide 5th wheel hitch as long as you use the Capture Plate #GY98FR. The Gen-Y pin boxes are specific on what they are replacements for,…

We have just what you need with the Global Link RV Entry Door Locking Latch Kit part #295-000019 which is correct for the size door cut out you have.

In order to determine the correct replacement landing gear for a trailer you need the measure the existing legs. The measurement you're looking for is the length of the outer tube and the distance between the weld stops. I see you're looking…
