Timbren offers the best selection of suspension products at a great price. Timbren carries a complete line of suspension stabilizer kits that are mounted between the vehicle chassis and the axle. Timbren SES Suspension Upgrades provide superior performance when carrying heavy loads. Their patented Aeon rubber springs are engineered to absorb road shock and provide stability to your vehicle. The Aeon rubber springs are an alternative to metal and air springs. They work in conjunction with the existing suspension to improve the ride of the vehicle and to protect the springs against overloading, road shocks, bottoming out, sway and spring failure.
