1–4-Inch Rear Four-Hole Adjustable Shackle Lift Kit
Add 1 to 4 inches of rear lift with four mounting-hole positions for stance adjustment or added tire clearance.
McBay Performance pioneered the adjustable rear shackle kit. Unlike common three-hole copies, the McBay four-hole design adds an extra adjustment position so you can fine-tune rear ride height.
