Parts For Install On A Roadmaster Comfort Ride Leaf Springs System On 2019 Grand Design Momentum


Hello, I have a 2019 Grand Design Momentum 395m. I am looking to maybe purchase the Roadmaster Leaf Spring and shock absorbers. What all parts will I need to make this work for my RV. I was thinking of purchasing new u bolts and new bolts to replace my wet bolts Thanks Thank you.

Your 2019 Grand Design Momentum 395m has a triple axle. We do have three options of the Roadmaster Comfort Ride Leaf Spring Suspension Kit.

5K Trailer Axles, part # RM-2460-2560-3
7K Trailer Axles, part # RM-2460-2570-3
8k, 3-1/2" Trailer Axles, part # RM-2470-2580-3

You will need to check your axles to see which kit is best for you. These kits do come with everything you need for the installation, except the tools. I have listed the tools you need below.

General Hand Tools
12” Long 5/16” Drill Bit
9/16” Socket and Wrench
3/4” Socket and Wrench
Torque Wrench
Blue Threadlocker part # LT37418

This system uses bushings that are self lubricating. Wet bolts will not be necessary. I would replace the u-bolts. I included a weblink to our u-bolt offerings below. I have also included product description links, a weblink to our Roadmaster Comfort Ride Systems, and a video of this system being installed on a 2020 Grand Design Momentum 5W Toy Hauler below.
