ARP Main Stud Kit for E30 M3 S14 Engine

This ARP main stud set for the E30 M3 eliminates main cap walk and fretting, as well as protects the threads in your engine block. Each S14 main stud is made using the best materials, process, design and engineering, which exceeds even the most stringent racing and aerospace specifications. This main stud kit includes hardened parallel-ground washers and aerospace quality nuts.

The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others. On the E30 M3, there's no reason to settle for anything less than the best, which is why we carry and use ARP fasteners and studs on our own BMW race cars.

ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.
