Timbren SES Suspension Enhancement System - Rear - GMRCK25D

PRODUCT OVERVIEW

This SES Suspension Upgrade fits the rear suspension of a Chevrolet Silverado 2500/3500 & GMC Sierra 2500/3500 truck. 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.

This SES Suspension Upgrade replaces the jounce stop on the frame. Its unique design ensures superb ride quality – loaded or unloaded. (There should be a 1/2" to 1-1/2" gap between rubber spring and axle to ensure unloaded ride quality.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds.

GMRCK25D replaces the bumpstops on the rear suspension of the 2011-2021 GMC Sierra and Chevy Silverado 2500HD and 3500HD pickup truck models.

This kit is rated at 8600 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.
