Wheel Stud Kit - M12x1.5 3.250/.509 Knurl

The Wheel Stud Kit - M12x1.5 3.250/.509 Knurl from ARP is engineered for late-model GM F-Body platforms requiring OEM-specification or upgraded fastening solutions. These studs form the critical mechanical bond between wheel and hub, and selecting premium-grade replacements ensures safety, reliability, and longevity under dynamic driving conditions. Whether you're rebuilding after brake service, upgrading worn factory studs, or preparing your muscle car for track duty, this five-piece kit delivers the exact fitment and durability demanded by precision automotive work.

Manufactured from chromoly steel and finished with cadmium plating, the Wheel Stud Kit - M12x1.5 3.250/.509 Knurl combines superior tensile strength with corrosion resistance essential for long-term wheel retention and safety. The M12x1.5 metric thread pitch ensures precise engagement with your vehicle's lug nuts, while the 0.509-inch knurl diameter provides the exact bearing surface required by OEM specifications. The 3.250-inch overall length accommodates standard GM F-Body hub designs without modification, and ARP's manufacturing tolerances guarantee consistent fit across all five studs in the set. Chromoly construction resists fatigue cracking under repeated thermal and vibrational stress, outperforming standard steel alternatives found in budget replacements.

Mechanics and F-Body enthusiasts trust ARP studs for high-performance applications, drag racing, autocross, and daily-driver reliability alike. Installation requires removal of wheels and brake components, with studs pressed or hammered into the hub from the rear—standard procedure on Camaro, Firebird, and Trans Am platforms. This kit covers one wheel; purchase multiples for complete four-wheel coverage. Proper torque sequencing with calibrated wrenches and quality lug nuts ensures maximum clamping force and eliminates the risk of rotor runout or wheel separation caused by loose or mismatched fasteners.
