Timbren Rear Suspension Enhancement System Kit, 8600 lb Capacity
Product Overview
Unstable loads while towing and hauling don’t just make for an uncomfortable ride. Difficult handling, rear sag, and corner sway create dangerous driving conditions — for you, your passengers, and other vehicles. Whether you’re towing your RV across the country or hauling hay down the highway, our Timbren Suspension Enhancement System (SES) kits are the best solution for upgrading your Chevrolet Silverado or GMC Sierra suspension. These kits level your load, making for a safe, controlled ride so smooth, you might forget you’re towing altogether. How? Our Aeon® rubber springs deliver a progressive spring rate. As load increases, the rubber springs push back harder, eliminating squat, sway, and roll. After installation, there should be a ½ inch to 1 ½ inch gap between the rubber spring and the vehicle’s frame — meaning you’ll enjoy a comfortable unloaded ride, too. What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, our kits require zero post-installation maintenance. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.Rear Kit, 8600 lb, For Chevrolet, GMC, For Silverado 1500, Sierra 150 0, Includes: 2 x Mounting Discs, 2 x Rubber Spacers, 2 x Timbren SES Suspensions, All Necessary Hardware
