3/8 Rocker Arm Studs - GM LS Engines

The COMP CAMS 3/8 Rocker Arm Studs for GM LS Engines are precision-engineered fasteners designed for high-performance engine builds requiring absolute reliability under extreme valve train stress. Built for forced-induction, high-RPM, and turbocharged LS platform applications, these studs feature an 8mm x 1.25 base thread with a 3/8-24 top thread specification and 1.500-inch effective stud length, delivering the clamping force and dimensional accuracy necessary to maintain rocker arm geometry during sustained boost or high-lift cam operation.

Constructed from hardened steel with black oxide finish, this set of 16 studs provides the corrosion resistance and wear characteristics required for both street and track environments. The 3/8-24 top thread accepts standard rocker arm nuts and geometry spacers without modification, maintaining OEM compatibility while delivering superior load retention compared to original equipment fasteners. The black oxide coating resists oxidation and discoloration, ensuring longevity in engine bays exposed to heat cycling and moisture.

These studs are essential for engine builders, performance shops, and LS swap enthusiasts upgrading to aggressive cam profiles, roller rockers, or high-ratio rocker arms where stock hardware cannot provide adequate preload retention. Whether building a dedicated drag car, street performance engine, or turbocharged truck platform, proper stud selection eliminates rocker arm lift-off and prevents catastrophic valve train failure during peak cylinder pressure events.

COMP CAMS rocker arm studs are recognized in the engine building and performance automotive community for consistent quality and precise thread specifications that ensure compatibility across LS variants (LS1, LS2, LS3, LS7, LT family) and aftermarket cylinder heads.
