Timbren Industries TRA5402 SES Suspension Enhancement System

The Timbren Industries TRA5402 SES (Suspension Enhancement System) is a heavy-duty rubber helper spring kit designed to provide progressive load support for trucks and commercial vehicles. This axle-mounted system replaces traditional steel helper springs or air bags with maintenance-free hollow rubber springs that engage automatically under load.

Key Features:

• Engineered Aeon® hollow rubber springs provide progressive load cushioning
• No air lines, compressors, or maintenance required
• Installs in approximately 30 minutes with basic hand tools
• Eliminates squat, sway, and bottoming out when towing or hauling
• All-weather performance - unaffected by temperature extremes
• Lifetime warranty against defects in materials and workmanship
• Made in Canada with premium rubber compounds

The TRA5402 SES kit improves vehicle stability, protects suspension components from damage, and delivers a smoother, more controlled ride when carrying heavy loads or towing trailers. The system activates only when needed, maintaining factory ride quality when unloaded.
