New for 2006 at Gearworks is the full assortment of Topline wheel accessories. Topline manufactures lug nuts and bolts, washers and studs, simulators, hub covers and spinners, and valve stems.
Designed to address the tightest tolerance lug holes found in tuner style wheels, our Hex Lugs and Hex Wheel Locks are case hardened and triple chrome plated for maximum durability. They feature a stepped adapter or key to fit both 3/4 and 13/16 lug wrenches, which are the most popular sizes for passenger cars.
