SES Rear Suspension Enhancement System

The Timbren SES GMRCK15S Rear Kit is a suspension enhancement system designed for GMC Sierra 1500 and Chevrolet Silverado 1500. It provides progressive suspension support to reduce sag and stabilize sway, particularly when hauling heavy loads or towing trailers. It features Aeon® rubber springs that deliver a progressive spring rate, meaning they work harder as the load increases to prevent rear-end sag. The system maintains a smooth ride even when unloaded and offers a quick bolt-on installation with included hardware. Timbren SES kits are built for long-term durability and come with a lifetime warranty and a 100-day money-back guarantee. Unlike airbags, they require no post-installation maintenance and can be installed in under 30 minutes. The kit replaces the jounce stop on the frame, making for a straightforward, bolt-on installation. This system is ideal for those who frequently tow or haul heavy loads and want to improve their vehicle's stability and ride quality without compromising unloaded ride comfort. The progressive spring rate ensures that the support increases as the load demands it, preventing bottoming out and improving overall handling. Rated Capacity: 8,600 lbs. Easy DIY installation. Lifetime Warranty and 100-Day Money Back Guarantee provide peace of mind and assurance of product quality. The system is engineered for durability and reliable performance in demanding conditions.
