Timbren SES Bump Stop | Rear | 8,600 lbs. Capacity

Timbren Suspension Kit GMRCK25D - Overview

Timbren Suspension Enhancement kit GMRCK25D works in conjunction with the existing suspension on your newer model Chevrolet Silverado 2500, 3500 and GMC Sierra 2500, 3500 trucks to improve the ride and to protect the vehicle against the effects of overloading. The Timbren rubber springs are mounted between the truck frame and the axle. They do not take the place of your trucks existing leaf spring, but work in conjunction with it, acting as a bump stop, to improve the ride of your truck and to protect springs against overloading.

Progressive Rate Springs

This Timbren Suspension Kit has hollow rubber springs to deliver a progressive spring rate. The more weight you put in your Silverado or Sierra that pushes down on the rubber Timbren springs the harder they work to prevent the rear end from sagging. Whether you're towing a heavy trailer or carrying a heavy load in the bed of your Silverado or Sierrra, the rubber hollow springs adjust automatically to keep the vehicle level at all times.

This Suspension Kit replaces the factory jounce bump stop on the frame of your Silverado and Sierra. It's unique, progressive design ensures superb ride quality, loaded or unloaded. There should be a 1" gap between the rubber Timbren spring and your trucks axle to ensure unloaded ride quality. Once you hook up your trailer or add a load to the back of your Silverado or Sierra truck, the springs will engage and help support the weight. Unlike some other helper spring options the SES Suspension Upgrade guarantees the best of both worlds.
