Expert Reply:

For front and rear suspension enhancement on a Chevrolet Express 4500 I recommend the SumoSprings Solo Custom Helper Springs # SSF-204-54 and # SSR-206-54. The SumoSprings will help absorb bumps and shocks as well as minimize sway and giving you a smoother ride overall. They have progressive load control and work independently to help reduce body roll and compensate for off-center loads. These durable helper springs are made of a high-density microcellular urethane and are maintenance-free.

I have attached some reviews of the SumoSprings for you to check out.

I installed the sat-206-54 on the rear of a 2021 express 4500 motorhome and they are about an inch from touching the rear axle. Unlike the pictures show in reviews. Is there a shim to make up the difference. The front is much better after installation of the SSF-204-54 but the rear still has sway I think because not touching axle.

@BillA SumoSprings typically have a gap like that so they aren't engaged all the time. For the motorhome that isn't as common since they're typically loaded up with extra weight that closes up the gap. SumoSprings does not have additional spacers available for sale but they might be able to send you a pair if you give them a call.
