Timbren SES Front Suspension Enhancement System for Select 1996-2020 GM, Hummer, and Mitsubishi (GMFK25S)

Fits select 1996-2020 Cadillac Escalade, Chevrolet Silverado/Tahoe/Suburban/Avalanche, GMC Sierra/Yukon, Hummer H2, and Mitsubishi Montero models.

The Timbren Suspension Enhancement System (SES) is engineered to improve vehicle stability and ride quality by providing additional support to the front suspension. These kits feature high-performance hollow rubber springs that act as a progressive load-leveler, absorbing road shocks and automatically adjusting to uneven loads. Unlike air bags, this system requires no airlines, no fittings, and zero maintenance, making it a reliable solution for vehicles that experience squatting or front-end sag.

Designed for a straightforward bolt-on installation, the GMFK25S kit replaces the factory bump stops and requires no drilling. The rubber cushions improve handling and reduce trailer sway by maintaining a level vehicle stance, even under heavy load conditions.
