This SES Suspension Upgrade fits the rear suspension of a Chevrolet 3500 & GMC C3500 cab & chassis truck. 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 bed of your truck, our hollow rubber springs adjust automatically to keep the vehicle level at all times.

• Easy to Install: There are no holes to drill and no air lines to route. Suspension Enhancement Kits install in a matter of minutes using basic hand tools.
• Easy to Use: Rubber cushions absorb road shock and automatically adjust to uneven loads or road conditions.
• Easy to Maintain: There are no air lines or fittings to allow leaks. Just bolt the kit on and you?re set for a lifetime of trouble-free suspension.
• Easy to Order: Our friendly, knowledgeable Technical Service Specialists are ready to assist you. Call with the year, make and model of your truck and they?ll do the rest.
