Throttle Down Kustoms CJ Shackle Revesal Kit for the Front Suspension. Takes the shackles and move them to the rear of the front leaf spring and then makes the front side of the leaf spring mount solid to the frame, by doing this you gain a very nice ride to the jeep. So when you hit a bump WITHOUT the SR your axle or tire moves forward witch causes a ruff ride. With the SR the axle moves rearward with the motion of the vehical upon Impact.
