Adjusting 5th Wheel Trailer Height To New Taller Truck

Question

Question:

switching a 16K Husky 5th wheel hitch from 2015 2500 HD to a 2021 25000 HA, bed depth is the same, however new truck sits 2inch higher. Steep driveway, should I use the slider hitch to compensate for the increased truck height while backing down steep drive? Thank You

A slider hitch would actually sit higher due to the slide rails so that would only further raise the connection point in your truck. You would need to either lower your pin box (if possible) to make sure you have 6" of bed clearance and/or need to flip the leaf springs on your RV over the axels with the Dexter Trailer Springs Over-Under Conversion Kit Item # K71-384-00 for 2-3/8" diameter axles or the Dexter Trailer Springs Over-Under Conversion Kit Item # K71-385-00 for 3" diameter axels.

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Yes, axle spread and wheel base by definition are the same measurements. You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this…

To correctly measure a leaf spring, you'll want to jack the trailer up on jack stands so the axle is hanging freely, then measure directly across from the center of one spring eye to the other, as shown in the provided diagram. The height of the…

Answer 11

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…
