Wheel Stud Kit - 1/2-20 3.435/.554 Knurl

The ARP Wheel Stud Kit - 1/2-20 3.435/.554 Knurl is a premium fastening solution engineered for serious automotive builders and restoration enthusiasts working on Mustang II and Pinto platforms. This five-stud set replaces factory hardware with premium-grade chromoly construction, delivering the strength and reliability demanded by high-performance applications, drag racing, and custom suspension builds. Whether you're upgrading a classic pony car or modernizing vintage chassis geometry, these wheel studs provide the foundation for safe, repeatable wheel mounting under demanding conditions.

Manufactured from chromoly alloy and finished with cadmium plating, the Wheel Stud Kit features a 1/2-20 thread pitch (industry standard for many classic and modern applications), 3.435-inch length, and a 0.554-inch knurl diameter designed for secure engagement in hub assemblies. The knurl geometry prevents slippage and ensures consistent clamping force when properly torqued, while chromoly's superior strength-to-weight ratio outperforms standard steel across temperature cycles and vibration stress. Cadmium coating provides corrosion resistance in harsh conditions, preserving thread integrity and reducing maintenance over years of use.

Mechanics and enthusiasts restoring or upgrading front suspension on Mustang II and Pinto models will find this stud set essential for maintaining OEM-correct geometry or transitioning to modern disk brake and suspension packages. Installation requires standard wheel removal and hub-specific tools; correct torque specification (typically 80–120 ft-lbs, depending on hub design) is critical for safety. ARP's reputation for precision manufacturing and quality control makes this kit a trusted choice when wheel retention cannot be compromised, whether for weekend cruising or competitive driving.
