Timbren Industries DR5500 SES Suspension Enhancement System

The Timbren Industries DR5500 SES (Suspension Enhancement System) is a progressive rubber spring suspension upgrade designed to improve your vehicle's load-carrying capacity and ride quality. This innovative system replaces traditional helper springs and air bags with maintenance-free Aeon® hollow rubber springs that compress progressively under load.

Key Features:

• Aeon® hollow rubber spring technology provides progressive spring rate that engages when needed
• Eliminates squat during towing and hauling while maintaining smooth unloaded ride
• No maintenance required—no air lines, compressors, or inflation needed
• Prevents trailer sway and improves steering control under heavy loads
• Bolt-on installation with no drilling required
• Reduces body roll and stabilizes suspension during cornering
• Works in all weather conditions, including extreme temperatures
• Lifetime warranty on rubber springs

The SES system is ideal for pickup trucks, SUVs, and commercial vehicles that frequently tow trailers or carry heavy cargo. The hollow rubber springs sit above the axle and only engage when the vehicle is under load, meaning you maintain factory ride quality when driving empty. Installation typically takes 30 minutes or less with basic hand tools.
