Compatible with 2015-2020 Ford F-150 models (All Cabs) (2WD/4WD), Belltech Street Performance lowering shock sets have been engineered to provide a premium ride quality for todays trucks and SUV's. Our engineers focused their attention on tuning the low speed compression characteristics of this shock absorber, which is responsible for controlling your Sport Truck or SUV's pitch and roll, dive and squat to help keep you confident and in control. The "Progressive" rebound tuning will complement large aftermarket wheels, keeping the ride smooth but firm and in control.
