Timbren Industries GMRG35 SES Suspension Enhancement System for Heavy Load Support

The Timbren Industries GMRG35 SES (Suspension Enhancement System) is a progressive rubber spring suspension upgrade designed to provide superior load support and ride quality when towing trailers or hauling heavy cargo. This bolt-on system replaces your factory bump stops with hollow rubber springs called Aeon® springs that engage progressively as the load increases, eliminating sag, sway, and bounce.

Key Features:

• Aeon® hollow rubber spring design provides progressive load support up to the vehicle's GVWR
• No-maintenance design with no air lines, compressors, or leak-prone components
• Bolt-on installation in about 30 minutes per axle with no drilling required
• Works automatically—engages only when carrying a load, maintains factory ride when unloaded
• Eliminates squat, sway, and roll when towing or hauling
• Lifetime warranty on rubber springs against cracking, splitting, or deformation
• Made in Canada with premium quality natural rubber compounds

The GMRG35 SES kit includes all necessary mounting hardware and is engineered as a vehicle-specific fitment for seamless integration with your suspension system. Unlike air bags or helper springs, Timbren SES requires zero maintenance and cannot leak or fail, making it an ideal solution for work trucks, RVs, and vehicles that regularly carry heavy loads.
