FR1504E
The Timbren auxiliary springs are an excellent upgrade for the rear axle of your 2015-2020 Ford F-150. 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.
