2 The kit's machined-aluminum coil-over shocks are manufactured to Control Freak's specifications by AFCO Racing. They are U.S.-made and rebuildable. Ride height is adjustable via the threaded collar on which the small end of the coil spring seats, and compression damping is quickly adjustable via a knob at the top of the shock (not visible in this photo). Note that, unlike typical coil-overs (which have a small-diameter spring mounted top and bottom to the damper unit), this kit has conical coils which at their wide (top) ends are of the same diameter, and seat in the same shock tower spring pockets as factory springs. The kit also includes new rubber spring isolators.
