8400 Late Model Air Shock

The 8400 Adjustable Air Shock gives you a wide range of adjustability that helps tune your car for a wide variety of track conditions. You now not only have the option of double or triple adjustable damping adjustment, you also have the option for single or dual rate air spring adjustments. This is not like other "air shocks" on the market. The 8400 Air Shock separates the air chamber from the damping. This allows you to have precise damping, while truly tuning spring rate based off air chamber volume. 

Current recommended uses include RF, LF, LR and 5th Coil.
