This 4" system features new front leaf springs that are designed to not only ride great, but will hold up to the abuse super duty trucks are made for. Progressively valved shocks are designed to increase offroad performance and provide excellent ride quality.
A heavy duty track bar is used to center the front axle and makes the kit much easier to install than a track bar bracket system. A 3" block is supplied for the rear to level the vehicle. This is the easiest installation and best value on the market for a 4" system.
