Timbren helper springs 2017-2020 Ford F-150 Raptor

The Timbren auxiliary springs are an excellent rear axle upgrade for your 2017+ Ford F-150 Raptor. The Timbren Auxiliary springs are hollow inside and are progressive springs which means that the more weight presses on the spring, the harder the spring works to ensure that the back does not collapse further. Whether the car is heavily loaded or you are towing a trailer, the Timbren auxiliary springs ensure that the vehicle remains straight. The auxiliary springs are placed in place of the Bump stops. The installation is simple and the result effective for a good price.
