Honda Main Stud Kit

The ARP Honda Main Stud Kit (part number 208-5403) is a high-performance upgrade designed specifically for 2-bolt main applications in Acura B-Series engines. This kit is ideal for engine builders and enthusiasts looking to enhance the reliability and performance of their builds, especially in high-RPM and forced-induction scenarios.

Constructed from high-strength chromoly steel and finished with a black oxide coating, this stud kit ensures superior clamping force consistency and fatigue resistance. Each stud is precision-manufactured to ARP's exacting tolerances and comes with 12-point nuts that facilitate repeatable torque values, minimizing the risk of thread galling during installation.

Engine builders and performance shops rely on this kit for B16, B17, B18, and related displacement variants, particularly when running elevated boost levels or aggressive tuning. The superior yield strength of chromoly over factory steel hardware translates to reliable block retention and reduced risk of catastrophic failures, making this kit a trusted choice in the Honda tuning community.
