Installed this on my 2006 Pleasure Way Lexor TS which is on a 2005 Chevy Express 3500 chassis. Installation was pretty easy. The van rides so much better now it doesn’t tilt anymore going around turns and it doesn’t bounce anymore going over bumps and pot holes.

Did not fit my Express 3500. Bought from Timbren and they fit my vehicle.

I used these on a 2019 Chevy express 3500 box truck. They do work as advertised and were super easy to put on. They also did not give me a rough ride at all because they actually don’t start working until after you’ve already put a lot of weight on the truck so the ride remains mostly the same at all times but has given me noticeable added stability with less sag when I’m loaded down. I have had them on my truck now for about a month. I hope they continue to perform.

Imstall these on my 2008 pleasure way lexor which has a weight of 9500lbs. installation was straight forward had to remove rear wheels to install, after that it took about 15 minutes to remove old bump stops and install new sumo springs. After installation the ride of the Rv was similar to a a car. there is very little side to side sway, it raise the rear up about a 1 1/2 inches, the front rose about a 1 inch. They also remove a lot of the bounce , sway , wobble from the ride. It was the best money i have ever spent. would recommend to any one with a class b motorhome. I also install the front ones. UPDATE FROM INSTALL YELLOW SPRINGS RIDE IS VERY HARD ON ROUGH SURFACES. YELLOW ARE NOT RIGHT FOR THIS APPLICATION SHOULD BE BLACK SPRINGS BAD PRODUCT DESCRIPTION, AMAZON VERY HELPFUL IN CORRECTING. WILL GIVE UPDATE AFTER THE CORRECT ITEMS ARE INSTALLED. BLACK SUMOSPRINGS
