How To Lift A Grand Design 376 5th Wheel Trailer

Question

Question:

We are considering purchase of a Grand Design 376TH 5th wheel. Is there a way to increase ground clearance in an inch basis to avoid ground obstacles while parking? I am interested in a inch due to the overall height of the rig and clearing bridges etc. Ideally I would like to be able to control this on the fly from my truck. Thanks for any insight you can provide.

In order to raise your Grand Design Momentum 376TH I recommend using an axle flip kit. You will need to have an axle diameter of either 2-3/8" or 3" in addition to the leaf springs being located under the trailer axles. If this is the case, I recommend the Dexter Trailer Springs Over-Under Conversion Kit part # K71-384-00 for 2-3/8" axles and part # K71-385-00 for 3" axles. You will need one kit per axle.

Unfortunately, these will not allow you to adjust the height from inside the cab of the tow vehicle.
