Part Notes:

Rear coilover kit is designed for 1 to 3 inch lowering. When used for drag racing we recommend insurance welding the brackets to the rear end. Vehicles running 10.50 or faster or running slicks require welding. Bolted brackets are suitable for street performance, auto-x and road race. Rear shocks may not clear all exhaust tail pipes.
