Rear SES Rubber Helper Spring Kit (RESOS1) by Timbren®. This SES Suspension Upgrade fits the rear suspension truck. Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. Engineered hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag. Whether you’re pulling a trailer or carrying a heavy load in the back of your SUV, hollow rubber springs adjust automatically to keep the vehicle level at all times. This SES Suspension Upgrade replaces the jounce stop on the frame. Its unique design ensures superb ride quality – loaded or unloaded. (There should be a 1/2" to 1-1/2" gap between rubber spring and axle to ensure unloaded ride quality. If the truck body is heavy, no clearance is necessary.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds.
| Capacity: 8600 lbs |
| Material: Rubber |

All of steel brackets and disks are lazer cut before they are painted with a durable long lasting powder coat finish to ensure protection and long life.

Timbren SES engages ONLY when you haul or tow and has zero maintenance, cause you have better things to do.
Timbren® Timbren Industries began in 1965 on the premise that suspensions could and should work better. That same year Timbren’s founder acquired the Canadian patent for rubber torsion suspensions. In 1968 Timbren introduced Aeon® rubber springs and began manufacturing SES (Suspension Enhancement System) suspension upgrade kits.
