Drop Coil Springs are a quick and easy way to lower a truck. Use just coils or combine with Drop Spindles for an even lower ride. If dropping the front 2" or more with coil springs then shorter front shocks are needed. If dropping the rear 4" or more then shorter rear drop shocks are needed. If dropping the rear of the truck 5" then a Frame C-Notch Kit and Adjustable Tracking Arm are needed.
