ARP Toyota Supra B58 CA625+ Head Stud Kit

The CA625+ alloy used in these ARP head studs offers a tensile strength of 260,000 psi, which is significantly higher than standard ARP 2000 material. This advanced alloy is also more resistant to fatigue and stretching under extreme cylinder pressures, making it a top choice for high-performance B58 engines found in the Toyota Supra. When you're pushing your engine hard, whether for track days or serious street performance, maintaining proper cylinder head clamping force is critical to prevent leaks and ensure consistent power delivery.

ARP meticulously machines these studs to exacting tolerances, ensuring a perfect fit and reliable performance. The kit includes all the necessary components for installation, such as the studs themselves, parallel ground washers, and high-performance nuts. ARP's reputation for well-built engine components means you can install these with confidence, knowing they are designed to handle the increased demands of a modified B58 engine. Proper installation is key, so always refer to the manufacturer's instructions for detailed guidance on torque sequences and specifications.

For B58 owners looking to maximize their engine's potential and ensure long-term reliability under stress, this head stud kit is a solid investment. It's designed to keep your cylinder head sealed tightly, even when dealing with increased boost or aggressive tuning. Ensure you have the correct tools and follow the recommended procedures for a successful installation.
