Fits select 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 models.

The Timbren SES (Suspension Enhancement System) is designed to eliminate vehicle squat and sagging under heavy loads. This kit replaces the factory bump stops with high-performance Aeon hollow rubber springs, providing a progressive spring rate that automatically adjusts to uneven loads and road conditions. By absorbing road shocks and stabilizing the vehicle, it significantly reduces trailer sway and improves overall handling while towing or hauling.

Constructed for durability and ease of use, this system requires zero maintenance—there are no air lines to leak and no fittings to manage. Installation is a straightforward bolt-on process that uses factory mounting points with no drilling required. This specific kit, MPN GMRSTT15, provides a reliable alternative to air bags for drivers seeking a set-it-and-forget-it suspension solution.
