This SES Suspension Upgrade fits the rear suspension of a Chevrolet C30, GMC C35/3500 and Workhorse P30 chassis (see below for full list of applications). Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. We’ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag. Whether you’re pulling a trailer or carrying a heavy load in the back of your vehicle, our hollow rubber springs adjust automatically to keep the vehicle level at all times.

This kit is rated at 6000 lbs capacity. Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
