3" ARP Corvette wheel studs are made out of 8740 Steel Alloy with a strength rating of 200,000 psi. ARP Corvette wheel studs are a heavy duty upgrade over the stock wheel studs. We highly recommend them to any Corvette competing in NCCC, any class of drag racing and HPDE cars that are running slicks. The studs are sold in packs of 5 and are cadmium plated for lasting protection. The stud size is 12mmX1.50 x 3.25". Fits all 1984-2013 Corvettes.
Note: Stock Corvette lugnuts cannot be used with these studs, they will bottom out and not tighten the wheel. Open-end lugnuts are required.
