Timbren Industries GMRG25C SES Suspension Enhancement System

The Timbren Industries GMRG25C SES (Suspension Enhancement System) provides a reliable suspension upgrade for GM 2500/3500 trucks, designed to improve ride quality and load-carrying capacity when towing or hauling heavy loads. This system uses hollow rubber springs that engage progressively as weight increases, providing additional support exactly when needed without affecting your truck's unloaded ride quality.

Key Features:

• Hollow rubber spring design activates progressively under load
• No air lines, compressors, or external components to maintain
• Eliminates squat, sway, and bottoming out when towing or hauling
• Maintenance-free operation with lifetime warranty
• Installs in approximately 30 minutes with basic hand tools
• Works with existing suspension system without modifications
• Reduces wear on factory suspension components

Unlike air bags or add-a-leaf systems, Timbren SES kits require zero maintenance and automatically adjust to load conditions. The hollow rubber springs (Aeon springs) are engineered to provide a smooth ride when unloaded while delivering up to several thousand pounds of additional load-leveling capacity when your truck is carrying cargo or towing a trailer. Installation is straightforward, mounting between the frame and axle using factory attachment points.
