ARP Wheel Stud Kit 1.95 In Length 5 Pack
Fits Most Subaru Models
100-7728
Overview:
The ARP Wheel Stud Kit features heat-treated 8740 chrome-moly steel studs designed as a durable and reliable upgrade for Subaru vehicles. Ideal for enthusiasts who participate in autocross, track days, or drag racing, these studs provide enhanced strength and durability over factory components. With a tensile strength of 200,000 psi, they are engineered to withstand the intense acceleration shock loads and lateral forces encountered during high-performance driving.
These studs are especially important if you plan to run slip-on wheel spacers thicker than 5mm, as their extended length ensures proper fitment and safety. Sold in packs of five, the studs are cadmium plated to resist corrosion and wear, making them a smart investment for performance and longevity.
Key Features:
Designed to meet the demands of motorsport and spirited driving, the ARP wheel studs offer the following key features:
- Constructed from heat-treated 8740 chrome-moly steel for superior strength and durability.
- Exceptional tensile strength of 200,000 psi to handle high shear and elongation forces.
- Cadmium plating provides excellent corrosion resistance and extended service life.
- Extended length of 1.95 inches (under head length) to accommodate slip-on spacers over 5mm thick.
- Precision knurl diameter of 0.565 inches ensures a secure fit in the hub.
- Thread size M12x1.25 compatible with most Subaru wheel nuts (nuts not included).
- Compatible with both cast iron/steel and aluminum hubs, with recommended drill bit size of 14mm for hub hole preparation.
- Sold in convenient packs of five studs, perfect for replacing all studs on one wheel.
Construction & Design:
Each wheel stud is crafted from premium 8740 chrome-moly steel, a material known for its high strength-to-weight ratio and excellent fatigue resistance. The studs undergo a heat treatment process to maximize tensile strength and durability under extreme conditions. The cadmium plating not only enhances corrosion resistance but also provides a smooth surface finish that facilitates easy installation and removal.
The extended length design is critical for vehicles running aftermarket wheel spacers thicker than 5mm, ensuring that the studs protrude sufficiently through the spacer and wheel for safe and secure fastening. The knurling on the stud shaft is precisely sized to lock firmly into the hub, preventing rotation and ensuring consistent torque retention.
Installation & Fitment:
This ARP wheel stud kit is a direct replacement for most Subaru models, making installation straightforward for enthusiasts and mechanics alike. The studs fit hubs made of cast iron, steel, or aluminum, with specific hub hole size tolerances to ensure proper seating. When installing on aluminum hubs, drilling with a 14mm bit may be necessary to achieve the correct hole diameter for the stud.
Note that nuts are not included with this kit and must be sourced separately. The extended length of these studs makes them essential when using slip-on wheel spacers thicker than 5mm, as factory studs are typically too short for safe installation in these cases.
- Fits most Subaru models with M12x1.25 wheel stud threads.
- May require drilling hub holes to 14mm diameter for aluminum hubs.
- No special tuning or modifications beyond hub drilling (if applicable) are required.
What's Included:
- Five (5) ARP heat-treated 8740 chrome-moly wheel studs, 1.95 inches in length.
Ideal For:
This wheel stud kit is perfect for Subaru owners who demand enhanced reliability and safety during high-performance driving. Whether you compete in autocross, track events, or drag racing, or simply want to upgrade your wheel hardware for added peace of mind when running aftermarket spacers, these ARP studs provide the strength and durability you need.
