Overview
A direct-replacement cylinder head bolt kit for the Toyota 4E-FTE, machined from ARP2000 material rated to 220,000 psi so it clamps the cylinder head far more securely than Toyota's single-use torque-to-yield bolts.
Built for turbocharged and high-compression 4E-FTE engines, where added boost and cylinder pressure can lift the head and fail the gasket on stock hardware. Unlike factory stretch bolts, ARP bolts are reusable.

Head gasket security
This is a bolt kit, not studs, and studs give more even clamping for very high boost; designed for the stock cylinder head.
