After 2 inch lift on 2010 Chevy Express cargo van Sumo Springs dramatically reduced the wobbling affect. In any case. These are definitely an upgrade from the factory bump stops. make sure and use soap and water or some type of lube to install them.

Installed these on my lifted 2006 Chevy Express 3500 and it handles corners and bumps much better than before. I highly recommend these to all van owners

These made a significant difference in front-end sway and dive. Handling and braking are noticeably better and it feels like the ride is more sport-oriented. A tad stiffer ride on bigger bumps but on small road bumps and cracks, these absorb the impact and significantly improved ride comfort. Highly recommended.

Install was easy, change the ride of RV much tighter when turning and less bounce over dips. Drove in the smokey mountains a lot of turns and up grades and down grades. A whole new ride very happy. Install did not have to remove wheel just jack up body and installed. Gave a 1 inch rise to rear of RV Front only rose about 1/2 inch.

These really helped the front end of my Chevy Express 3500. They reduced the front sway but also soak up the bumps waaay better than the stock pieces. I highly recommend these along with Bilsteins all around.

Seems the manufacturer has not tested on models earlier than 2007- these fit my 2005 just fine.tools:2 large dull tip screwdriverslarge channel locks ( mine about 16") or even vice gripsjackjackstandssupport front of van with jackstands, tires off the ground- rear tireschocked, parking brake setworking from the rear of the front tires and steering turned to give accessThe original GM bumpstops come out with the 2 screwdrivers pushed up along the inside and then levered out out of the cup.then use a large pair of channel locks to push back 2 of the 4 tangs - the rear and outsidethe new bumpstop can be pushed and wiggled into place so that about 280º is in the cupthen place a jack under the A arm and lift up to compress the bumpstop against the cup, with your 2 DULL large screwdrivers work the remaining bumpstop into the cup.once it is in, use screwdriver push the tangs back to previous position, you'll have about 3/16" gapsame other side, after test drive check the bumpstop is in position and check the tangsthe first side took me 40 minutes while I figured out tools and method, the 2nd one took 15 minutesresults are good, I chose the 47 to help control swaying on turns. my class B RV has alot of height up high and these help with the waddle. I also have their product on the rear

Installed on a 2017-Chevrolet-Express 3500 4x4. Well built product. Works exceptionally well. Has all but eliminated front end roll when cornering. Has helped to smooth out my ride. Only issue with buying from Amazon, is that SuperSprings will not honour their lifetime warranty. This seller should have noted this issue in their description.
