Ultimate Engine Reliability for Honda H22A4

When you are pushing your Honda H22A4 VTEC engine to the limit, stock main bolts simply aren't enough. The ARP Main Stud Kit (208-5401) is the industry standard for high-performance engine builds, providing the superior clamping force required to keep your main caps seated under extreme cylinder pressures and high RPMs.

Why Choose ARP Main Studs?

• 8740 Chromoly Steel: Forged for superior tensile strength and fatigue resistance.
• Precision Threads: Rolled threads ensure consistent torque readings and prevent galling.
• Increased Clamping Force: Keeps the crankshaft stable, reducing bearing wear and preventing block distortion.
• Complete Kit: Includes high-quality nuts and hardened parallel-ground washers.

Engineered to exceed OEM specifications, these studs provide the peace of mind needed for both street-driven builds and dedicated track cars. Whether you are running forced induction or a high-compression naturally aspirated setup, ARP hardware is the foundation of a reliable bottom end. By utilizing a stud design, you ensure a more accurate torque application and a tighter seal that prevents main cap walk, a common failure point in high-output Honda engines. Invest in the best engine protection available for your H22 build. Find all your essential performance engine components at GGCRACING.
