ARP Head Stud Kit – Honda / Acura B18A & B18B

ARP 208-4302 Head Stud Kit

Upgrade your B-series engine’s top end with the ARP Head Stud Kit for Honda and Acura B18A & B18B engines. This kit replaces factory head bolts with precision-engineered studs that provide superior clamping force, ensuring a consistent and secure cylinder head seal — even under extreme boost or high-rpm conditions.

Manufactured from premium 8740 chrome-moly steel and heat-treated to a tensile strength of around 190,000 psi, each stud is centerless-ground and thread-rolled after heat treatment for exceptional strength and fatigue resistance. The kit includes 12-point nuts and hardened washers for even, repeatable torque values and precise head gasket compression.
