Header Stud Kit - 6pt. 3/8 x 1.670 OAL (12)

The Header Stud Kit - 6pt. 3/8 x 1.670 OAL (12) from ARP is a precision fastening solution engineered for high-performance engine builds where cylinder head integrity is crucial. This kit is ideal for engine builders and technicians who require reliable fastening solutions in demanding applications.

ARP studs are manufactured to exacting tolerances using high-strength alloy steel, ensuring consistent preload tension and superior fatigue resistance under temperature cycling and shock loads. The 6-point fastener design distributes load across a larger contact surface, reducing stress concentration and preventing bolt strip-out, which is essential in high-vibration environments.

This 12-piece kit provides a complete fastening solution for header assemblies on most standard platforms, making it an excellent choice for mechanics and technicians working on custom or high-demand engine builds.
