BBC Rocker Arm Stud Kit 7/16 (2)

The ARP BBC Rocker Arm Stud Kit 7/16 (2) represents the gold standard for big-block Chevrolet rocker arm fastening in high-performance engine builds. These dual studs are engineered for builders and mechanics who demand reliability under extreme valve train stress, whether you're running a street performance 454 or preparing a competition-grade BBC mill. Purpose-built to replace factory hardware with superior clamping force and fatigue resistance, this pair delivers the security needed when horsepower climbs and valve spring pressures intensify.

Manufactured from chromoly steel, the ARP BBC Rocker Arm Stud Kit 7/16 features a dual-thread design: a 7/16-14 base thread for block engagement and a 7/16-20 top thread for rocker arm nut retention. This geometry maximizes thread engagement in the cylinder head while ensuring consistent preload across the rocker assembly. The 1.750-inch effective stud length provides optimal geometry for BBC rocker geometry and aftermarket aluminum heads, while the chromoly construction resists galling and delivers predictable clamp load compared to factory cast-iron studs. ARP's manufacturing process guarantees concentricity and surface finish that prevent stud relaxation under thermal cycling and high-RPM operation.

Installers and engine builders rely on this kit for stroker builds, ported-and-polished heads, and solid-lifter cam conversions where valve train stability is non-negotiable. The pair configuration covers two rocker positions, making it ideal for staged upgrades or complete big-block refreshes. Torque to specification using a quality wrench or ARP stud installer tool to ensure even preload and eliminate rocker arm walk. Compatible with all BBC applications using 7/16 stud diameter, this kit integrates seamlessly with stock or performance rocker arms and pairs perfectly with corresponding ARP fastener solutions for complete valve train security.
