Improve your vehicle's ride quality and handling with Timbren's suspension enhancement system (SES). Factory bump stops may work well when your vehicle is unloaded, but issues arise when approaching its payload or towing capacities. With a trailer on the hitch, a fully loaded bed, or a van full of gear, drivers commonly experience excessive bouncing and bottoming out of the rear suspension. Timbren suspension enhancement systems serve as a rubber spring, increasing resistance and limiting travel while loaded for a more stable and comfortable ride. Timbren suspension enhancement systems not only increase load handling but also reduce sag and sway while towing, cushion shocks, and help level your truck or SUV. Timbren SES offers superior towing and hauling capacity for bulletproof comfort and an exceptional ride compared to competitors. Timbren suspension enhancement systems are built to last from Timbren's patented Aeon rubber. | Timbren Rear SES FR250SDG
