About This Product

Timbren DRTT3500D SES Severe Service Rear Suspension Enhancement System - 8,000 lb Load Support for Truck Campers & Top-Heavy Loads | Reduces Sag, Sway & Roll | Zero-Maintenance | Easy DIY Install is a Timbren suspension product built for drivers who need dependable load support, improved stability, and a cleaner ride when towing, hauling, or driving with heavier cargo.

Key Features

• Maximum Stability for Top-Heavy Loads - Built specifically for truck campers, salt spreaders, and other high center-of-gravity loads. The single-convoluted Aeon spring delivers aggressive weight resistance to eliminate squat, sway, and body roll for safer, more confident handling.
• Smooth & Controlled Highway Handling - No more white-knuckle driving in crosswinds. As your load increases, the progressive spring rate pushes back harder, keeping your vehicle level, centered, and stable - even with demanding truck camper setups.
• Comfortable Ride When Unloaded - Engineered with a "1" gap between the rubber spring and the frame, allowing your truck to ride normally when empty. Enjoy maximum stability only when you need it.
• Zero-Maintenance Reliability - No air bags, hoses, or compressors to fail. Timbren SES severe-service kits require absolutely no upkeep after installation and outperform foam or air systems in all weather conditions.
• Heavy-Duty 8,000 lb Load Support - Designed for the toughest hauling scenarios. The ultra-durable Aeon rubber compound delivers long-lasting performance under extreme weight, temperatures, and road conditions.
• Fast, Easy DIY Installation - Installs using existing factory mounting points with no drilling, no air lines, and no special tools. Most users are ready to haul in under 30 minutes right from their driveway.
