Key Features
Engineered for strength and reliability, the ARP Toyota Supra B58 CA625+ Head Stud Kit offers the following key features:
- Manufactured from ARP’s proprietary CA625+ alloy, providing exceptional tensile strength and fatigue resistance
- Designed specifically for the B58 inline-six engine found in the 2020–2026 Toyota GR Supra
- Precision-machined threads for consistent torque and clamping force
- Improved clamping load over factory head bolts to prevent head gasket leaks under high boost
- Corrosion-resistant finish to ensure long-term durability
- Includes all necessary studs and nuts for a complete head stud replacement
- Compatible with OEM and aftermarket cylinder heads without modification
- Ideal for high-performance builds, including turbocharged and supercharged setups
Construction & Design
The head studs are crafted from ARP’s CA625+ alloy, a proprietary material known for its superior strength-to-weight ratio and excellent resistance to stretching and fatigue. This advanced alloy outperforms standard steel bolts, making it ideal for the demanding environment inside a high-performance engine. Each stud is precision-machined to exacting tolerances, ensuring a perfect fit and consistent torque application during installation. The studs feature a corrosion-resistant coating to protect against rust and wear, extending the lifespan of the fasteners even in harsh conditions.
The design focuses on maintaining uniform clamping pressure across the cylinder head, which is critical for preventing head gasket failure and maintaining engine integrity during high-stress operation.
Installation & Fitment
This ARP head stud kit is a direct fit replacement for the factory head bolts on the 2020–2026 Toyota GR Supra with the B58 engine. Installation requires removal of the cylinder head and careful torqueing of the studs to ARP’s specifications, typically using a calibrated torque wrench and following a specific tightening sequence. No modifications to the engine or cylinder head are necessary, making it a straightforward upgrade for experienced mechanics or professional shops. Proper installation ensures maximum performance and reliability benefits.

What does the ETA date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
