got them in a little had but once they work great

I added the front and rear sumosprings to my 14k lb chassis chevy 4500 motorhome. Collectively they have taken the ride from rough, painful and downright terrible to outstanding. The harsh bumps that existed from concrete freeways with large expansion joints is a thing of the past. I used to hit bridge transitions and the whole motorhome would slam, rattling the cabinets and dishes. The back passengers complained at the quality of the ride to the point they were car sick. The best benefit is the side to side sway is nearly gone. It's extremely improved. Large trucks used to suck me into their lane as they start to pass and then push me away as they would take the lead. Wyoming winds would make the drive tiring. These little guys have all but eliminated the sway. The motorhome isn't a sports car but it's tight while cornering and feels more like a car than a motorhome. Windy mountain roads are now a one-handed operation. I can't say enough how these improved the ride! They installed in minutes (once i figured it out). Make sure you jack up the frame far enough to create the gap between the chassis and the axle. You can then slide them into place easily. If there is one thing you should do for a van/truck based chassis motorhome it's this.

Très bon produit simple à installer qui donne un beau look et améliore le comportement routier

Very effective devices, and worth the effort.Installation on Chevy Express 4500 (RV): Jack up the wheel to where it spins so that you get the maximum distance. Pop out the old one according to the instructions (super easy). For getting the new one in, I found that twisting it as it goes in worked well. It doesn't have to be centered or positioned properly. It just has to be inside the cup. I figured that out with the first one, and then the second was very quick and easy. When I lowered the vehicle back down to the ground, the weight of the vehicle mostly seated the sumospring into the socket. After a short drive it was fully seated.

It’s amazing the difference these made in the handling of the RV. Installed them onto my 2006 Chevy 3500 RV chassis. More responsive and tracks better in windy conditions. Highly recommend this product and it’s an inexpensive upgrade. - I was a bus driver for 12 years.
