ARP Toyota 1.6L 4AGE 20V Head Stud Kit

ARP's 1.6L 4AGE 20V head stud kit uses 8740 chromoly steel, a well-known material for its strength and durability in high-stress engine applications. These studs are heat-treated and then quenched and tempered to achieve a tensile strength of 200,000 psi. This level of strength is crucial for maintaining proper clamping force on your cylinder head, especially in performance-oriented 4AGE engines.

When you're rebuilding the top end of your 1.6L 4AGE 20V, using ARP head studs is a smart move to ensure the cylinder head stays securely seated against the block. This helps prevent leaks and maintains consistent compression. The kit includes all the necessary studs, nuts, and washers, and ARP provides their special ARP Ultra-Torque fastener lubricant, which is designed to ensure accurate torque readings during installation. Following the manufacturer's recommended torque sequence and values is key to getting the most out of this well-built kit.
