ARP Subaru Wheel Studs - Extended Length 2.535"

The Perfect Mid-Length Upgrade for Street or Trail

The ARP 100-7729 Wheel Stud Kit provides a 2.535" Underhead Length (UHL), making it the ideal upgrade for Subaru owners who need more thread engagement than stock but want to maintain a clean look. Whether you’re adding small spacers to your Outback for a more aggressive stance or beefing up your WRX for spirited driving, these studs provide the ultimate peace of mind.

Unrivaled Strength & Precision
Manufactured from 8740 chromoly steel and heat-treated to a 200,000 PSI tensile strength, these studs are significantly stronger than OEM hardware. Like the shorter 100-7728, this kit features a 0.200" speed nose (starter tip) that prevents cross-threading and makes wheel changes significantly faster and safer.

• Versatile Length: At 2.535", these allow for the safe use of small wheel spacers (up to 10-15mm) while still fitting under many closed-ended lug nuts.
• Corrosion Protection: Finished in a durable cadmium plating to resist rust and road salt—essential for daily drivers and off-road builds.
• Bulletproof Reliability: Rated to handle the high-torque loads of modified engines and the lateral stress of oversized off-road tires.
• Direct Fit: Engineered specifically for Subaru and Toyota GR86/BRZ hubs.

Fitment Applications:

• Subaru WRX: 2002–2026
• Subaru STI: 2004–2021
• Subaru BRZ / Toyota GR86 / Scion FR-S: 2013+
• Subaru Forester / Crosstrek / Impreza / Outback: Most models using M12x1.25 threads.
• 1993–2007 Subaru Impreza (Non-Turbo / Base / RS): Fits Front ONLY. The rear hubs often use a smaller 12.3mm (0.480") knurl
