Common questions
Which set size do I need?
Count your lugs: a 20-piece set covers four 5-lug wheels, 24 pieces cover four 6-lug wheels, and 32 pieces cover four 8-lug wheels. Pick the option that matches your vehicle when ordering.
Will a regular spline key remove these?
No. The duplex spline pattern takes the matching duplex key that ships with the set, and extra duplex keys are available if you want a spare. The key itself drives with a common 3/4" or 13/16" socket.
