Timbren Industries DRTT3500D Rear Severe Service Suspension Enhancement System

The Timbren DRTT3500D Severe Service Rear Suspension Enhancement System improves suspension performance when hauling heavy loads and is specifically designed for demanding applications. This severe service kit features a stiffer rubber compound intended for applications where weight is always on the vehicle, such as aerial devices, dump bodies, or slide-in campers.

Key Features:

• Maximum safe load capacity of 8,000 lbs per pair
• Single-convoluted Aeon Springs that resist weight more aggressively due to their shorter and wider design
• Includes two rubber springs (3-9/16 inches tall and 4-1/4 inches wide), two 1 inch tall rubber spacers, and powder-coated steel mounting brackets
• Requires zero post-installation maintenance unlike air bags
• Can be installed in under 30 minutes from your driveway
• No modifications required to your vehicle
• Backed by a lifetime warranty

The patented Aeon hollow rubber springs cushion and absorb road shocks and automatically adjust to uneven loads and road conditions. These suspension enhancement systems sense vehicle body movement and automatically increase roll stability, eliminating wallowing along the highway and drifting in crosswinds. Rubber cushions absorb road shocks and automatically adjust to uneven loads or road conditions with no airlines or fittings to allow leaks—simply bolt the kit on for a lifetime of trouble-free suspension.

Important Note: Even though you're increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
