I bought the rear Sumo springs for my 2005 Damon intruder w22. Never got the opportunity to install because I was sent an open box with missing parts. Contacted the super spring store as requested started a warranty was told I would get a phone call nothing has been done with the warranty nor did I receive a phone call from super spring so I can't give you any feedback on how this install went never got the opportunity

The sumo brackets for the w22 chassis, if mounted per factory instructions, are 6 inches too short to mount original bumper & sumo bracket to the original frame bracket. Therefore I had to drill a new hole in the frame to move the bracket about 6” back. Also the predrilled threaded holes in the bracket to mount the springs, did not match the holes in the threaded holes in the top of the springs. Luckily, I am a retired welder fabricator & was capable of correcting their fabrication errors. I have not road tested them yet, but so far these simple errors have certainly not instilled confidence in the Sumo products.

This was installed on a Workhorse chassis. Made a big improvement in the ride. Had already installed the Super Springs on the front so this completed the total job. Recommend for ALL classes of RV's.

Everyone raves about this product and it does help but some of the city roads and thruways are in such disrepair it can still be a bone jarring ride.

These springs GREATLY IMPROVED my overall ride in the coach. I now have both the front and rear units installed and the difference is amazing. The ride is firmer with more control. A side benefit has been that with less suspension travel, the coach is actually quieter inside than before. Pretty easy install too. Worth every penny.

These are great. Best thing I've done for my 2006 Winnebago Voyage on a Workhorse chassis. Not quite air bag quality ride, but a notable improvement...more stable, less tiring ride.
