Wheel Stud Kit - 7/16-20 3.200/.580 Knurl (5)

The Wheel Stud Kit - 7/16-20 3.200/.580 Knurl (5) from ARP represents the gold standard for upgrading OEM wheel studs on modified vehicles. Designed for serious enthusiasts and mechanics who demand reliability under extreme conditions, this five-piece kit addresses a critical weak point in high-performance applications where stock fasteners simply cannot handle sustained loads. Whether you're running larger brakes, aggressive wheel fitments, or pushing your engine's output, upgrading to ARP studs is foundational work that prevents catastrophic wheel detachment.

ARP's 7/16-20 thread pitch studs feature a 3.200-inch length and 0.580-inch knurl diameter, engineered to provide superior clamping force and fatigue resistance compared to mild steel OEM hardware. The knurled design ensures a secure fit in the wheel hub while the precision threading maintains consistent preload across the joint—critical for preventing micro-motion that leads to fastener loosening and potential wheel separation. Each stud is manufactured from premium-grade alloy steel and heat-treated to exacting specifications, delivering the tensile strength and reliability that professional builders and track enthusiasts trust.

This kit is ideal for street performance builds, track day vehicles, and any application requiring enhanced structural integrity at the wheel interface. Installation is straightforward for experienced mechanics—press the knurled studs into the hub using proper tooling to avoid deformation, then torque wheels to manufacturer specifications using a calibrated wrench. A five-pack allows you to replace studs across a complete vehicle or maintain a spare set for maintenance intervals. Verify your vehicle's hub geometry and thread pitch before ordering to ensure compatibility with your specific make and model.
