The ARP Mazda Main Stud Kit (ARP218-5401) is an essential upgrade for serious Mazda engine builders focused on enhancing reliability and durability. This kit is particularly beneficial for those assembling stock rebuilds or modified engines that require a robust solution to prevent issues like head lift and crankshaft walk under increased power levels.
Manufactured from premium ARP2000 alloy steel, these main studs offer superior tensile strength and fatigue resistance compared to factory hardware. The design is intended to prevent gasket blow-out and reduce block deflection, ensuring even distribution of clamping force across the bearing saddles, which is critical for maintaining oil pressure stability in high-performance applications.
Ideal for engine builders and performance enthusiasts, this kit is suitable for both rotary and piston Mazda engines. It is designed for those looking to push beyond OEM power levels or seeking added insurance against fatigue failure in modified applications. Installation requires basic engine assembly knowledge and adherence to torque specifications for optimal performance.
