Rocker Arm Stud - BBC Exhaust (Long)

The Rocker Arm Stud – BBC Exhaust (Long) by DART is a precision engine component designed specifically for big-block Chevrolet builds that require reliability under high-load exhaust manifold conditions. This stud is essential for connecting the rocker arm assembly to the cylinder head, ensuring that valve train geometry is maintained even under high RPM and thermal cycling.

Constructed to exacting tolerances, this long configuration rocker arm stud provides sufficient thread engagement for secure clamping while maintaining the necessary standoff distance for rocker geometry calibration. The quality material used in its construction resists thread galling during installation and can withstand the cyclic clamping forces generated by high-lift camshaft profiles and aggressive valve spring pressures.

Engine builders and mechanics working with BBC platforms, particularly those involving 454, 427, and 396 applications, will find DART rocker arm studs indispensable for exhaust manifold and tunnel-port configurations. Proper selection of rocker arm studs is crucial for achieving optimal valve timing accuracy and overall engine durability.
