Vehicle Fitment

• Universal - M12-1.25 x M12-1.75 thread pattern; verify application fitment before installation

Fitment Notes

• This is a universal single stud sold individually; confirm thread pitch and OAL requirements for your specific engine application before ordering
• Dual thread design (M12-1.25 block/head end; M12-1.75 nut end) - not compatible with applications requiring matching thread pitch on both ends

Features

• Dual thread design: M12-1.25 on the block/head end, M12-1.75 on the nut end for versatile installation
• 7.300-inch overall length provides extended clamping reach for performance engine builds
• Manufactured from high-strength ARP proprietary alloy steel for superior tensile and yield strength
• Heat-treated for consistent material hardness across the full stud length

Product Description

The ARP AU7.300-10B is a precision-machined single engine stud designed for builders who need a reliable, high-strength fastener with a dual thread configuration. With M12-1.25 threads on the installation end and M12-1.75 threads on the nut end, this stud accommodates applications that require different thread pitches on each side - common in certain head stud and main stud configurations. At 7.300 inches overall length, it provides the reach needed for performance and custom engine setups where stock fasteners fall short.

ARP studs are machined to exacting tolerances and heat-treated for consistent hardness throughout, making them significantly more reliable than factory torque-to-yield hardware. They can be reused across multiple builds as long as they remain within specification, offering long-term value for engine builders and performance shops. This stud is sold individually, making it an ideal solution for replacing a single damaged fastener or completing a custom fastener kit for a specific application.
