Timbren Industries GMRREN SES Suspension Enhancement System Helper Springs

The Timbren Industries GMRREN SES (Suspension Enhancement System) provides a reliable suspension upgrade for trucks and SUVs that frequently tow trailers or haul heavy loads. This system uses hollow rubber springs that act as progressive-rate helper springs, automatically engaging when weight is added to your vehicle.

Key Features:

• Hollow rubber spring design provides progressive rate cushioning that activates under load
• No maintenance required—no air lines, compressors, or inflation needed
• Reduces body roll, sway, and bottoming out when towing or hauling
• Helps maintain level ride height under heavy loads
• Preserves factory ride quality when unloaded
• Aeon rubber construction for durability and resistance to road chemicals
• Installs in approximately one hour with basic hand tools
• Lifetime warranty on rubber springs

Unlike airbags or traditional steel helper springs, Timbren SES springs require zero maintenance and automatically adjust to load conditions. The hollow rubber design compresses progressively as weight increases, providing just the right amount of support exactly when needed. When unloaded, the springs remain inactive, preserving your vehicle's factory ride characteristics.
