12mm x1.25 x 2.535 Wheel Stud Kit (5pk) Subaru

The ARP 12mm x 1.25 x 2.535 Wheel Stud Kit (5-pack) for Subaru is engineered for drivers and mechanics who demand reliability under the stresses of daily driving, track use, and performance modifications. These chromoly wheel studs replace factory fasteners with superior material strength and precision threading, ensuring secure wheel attachment across a range of driving conditions. The 12mm diameter with 1.25 metric pitch thread and 2.535-inch length deliver exact fitment for Subaru applications, while the 0.565-inch knurl diameter maintains compatibility with OEM and aftermarket wheel hubs.

Chromoly construction offers significantly greater tensile strength than standard steel studs, resisting deformation and fatigue cracking under repeated torque cycles and thermal stress. The cadmium finish provides corrosion resistance in wet and salt-exposed environments, extending service life. The knurled shank diameter grips the wheel hub securely, reducing the risk of stud pull-through—a critical concern when running larger wheels, lowered suspensions, or aggressive track duty. Each kit contains five studs, the standard count for most Subaru wheel configurations.

This kit suits Subaru WRX owners, turbocharged boxer enthusiasts, and mechanics performing suspension upgrades, wheel replacements, or stud reconditioning. Whether you're addressing worn studs, upgrading to performance wheels, or reinforcing fasteners for road or circuit use, ARP studs meet the demands of Subaru's strong platform. Proper installation requires correct torque specification to the wheel hub—consult your Subaru service manual or ARP technical documentation for your specific model year and application.

ARP is recognized in the automotive performance community for fastener engineering and reliability. These wheel studs are manufactured to precise tolerances and inspected to ensure thread accuracy and material consistency, making them a practical choice for any Subaru owner prioritizing safety and longevity in a critical fastening application.
