AFCO's steel non-adjustable strut is valved for maximum weight transfer and includes our exclusive bounce control (BNC) valving to get you hooked up and down the track fast. Can be used right out of the box with a stock position spring setup or you can reduce front end weight and add ride height adjustability by making them a coil-over setup. To make a coil-over setup requires purchase of adjustable caster/camber plates (#40022, 40023 or 40024), a #29022 coil-over kit, and a lifetime warrantied set of AFCOIL 2.625" i.d. Yellow or Extreme Chrome coil-over springs. Struts sold individually.
