S/S Stud Kit - (4) M8 x 1.25in x 45mm

The ARP S/S Stud Kit with (4) M8 x 1.25in x 45mm studs is a premium fastening solution engineered for high-performance engine builds, transmission assemblies, and critical mechanical applications. Designed for technicians and enthusiasts who demand reliability under extreme conditions, this stainless steel stud kit eliminates the risk of bolt failure and thread stripping that standard fasteners cannot withstand. Each set includes four polished studs paired with matching 12-point nuts, offering superior clamping force distribution and repeatable torque specifications.

Manufactured from premium stainless steel and featuring a polished finish, these M8 x 1.25 studs resist corrosion while maintaining consistent mechanical properties across thermal cycles. The 45mm length provides adequate thread engagement for robust holding power, while the 12-point nut design minimizes rounding and ensures precision torque application. ARP's engineering eliminates the weak point inherent in traditional bolts—where the shank transitions to the threaded section—by using a full-diameter stud that distributes stress evenly along the fastening interface. This geometry directly improves clamping load retention and reduces fatigue failure risk in high-vibration or high-temperature environments.

This universal stud kit is ideal for motorsports applications, heavy-duty mechanical assembly, and any situation where fastener integrity is non-negotiable. Compatible across a wide range of equipment platforms, the M8 x 1.25 thread pitch and polished stainless construction make these studs suitable for both standard and custom builds. Installation requires standard socket tools; proper torque specifications should be referenced from the applicable assembly manual. The compact kit dimensions and modest weight make it easy to stock for maintenance or rapid deployment during rebuild operations.
