Mitsubishi Main Stud Kit 12pt.

The ARP Mitsubishi Main Stud Kit 12pt. is a precision-engineered fastener system designed for professional engine builders, performance technicians, and serious automotive enthusiasts who demand reliability in high-stress applications. This chromoly main stud kit replaces factory fasteners on Mitsubishi 4-cylinder engines, providing enhanced clamping force and vibration resistance compared to conventional bolts.

Constructed from chromoly steel and finished in black oxide coating, the Mitsubishi Main Stud Kit 12pt. delivers consistent advantages over OEM hardware. Chromoly material offers superior tensile strength and fatigue resistance, allowing the studs to maintain clamp load under thermal cycling and engine vibration. The 12-point nut design enhances grip geometry during installation, promoting uniform torque distribution across all two main bolt positions.

This kit is particularly beneficial for any Mitsubishi 4-cylinder engine experiencing elevated boost pressures or forced induction modifications. It is ideal for both street and competition environments, providing an upgrade for those looking to enhance their engine's performance and reliability.
