Brian Crower Toyota A90/Supra B58 ARP 203-4705 ARP Head Stud Kit

If you're pushing your Toyota A90/Supra B58 engine beyond stock power levels, especially with forced induction or increased boost, you'll want to make sure the cylinder head stays firmly sealed to the block. That's where a strong set of head studs like this kit from Brian Crower, using ARP fasteners, comes in. These studs are designed to handle the significantly higher clamping loads that come with a performance tune, preventing head gasket failure and maintaining consistent compression.

This kit utilizes ARP's well-known studs, which are made from a high-strength aerospace alloy and heat-treated to achieve superior tensile strength. They are installed with special nuts and washers, all included in the kit. Unlike factory head bolts that are often torque-to-yield and meant for single use, these studs are reusable and offer a more consistent and reliable clamping force. The threads are rolled after heat-treating for improved fatigue life, and the studs are black oxide finished for corrosion resistance. This is a solid option for anyone serious about building a reliable, high-output B58 engine.

When installing these, remember that proper preparation of the block and head surfaces is crucial, as is following the correct torque sequence and procedure as outlined by ARP. This kit is a critical component for ensuring the longevity and performance of your modified engine.
