BBM Rocker Arm Shafts - Pair

The BBM Rocker Arm Shafts – Pair from SHARP ROCKERS are precision-engineered components designed for serious engine builders and performance mechanics seeking to upgrade or replace worn rocker arm assemblies. These shafts form the backbone of your valvetrain, directly controlling the timing and lift of your intake and exhaust valves. Whether you're rebuilding a tired engine, upgrading to a higher-lift camshaft profile, or restoring a classic platform, quality rocker arm shafts are non-negotiable—they bear constant cyclical stress and must maintain absolute concentricity to prevent valve float and premature wear.

SHARP ROCKERS' BBM rocker arm shafts are manufactured to tight tolerances that ensure consistent bore fit and proper oil flow through internal galleries, critical for reliable valve actuation under sustained RPM and aggressive cam profiles. The 21.05-inch length accommodates full-width rocker assemblies, while the compact 1-inch diameter provides the strength-to-weight ratio necessary for both street and competition builds. Hard-chrome finish resists galling and fretting corrosion, extending service life even in high-humidity storage or prolonged periods between rebuilds. Pair configuration means both intake and exhaust shafts arrive ready for installation, eliminating the need to source components separately.

This product is ideal for engine shops, restoration specialists, and enthusiasts performing top-end overhauls on Mopars or similar platforms requiring PR7001-78 specification shafts. Installation requires careful alignment during assembly to prevent rocker arm rocking or binding, and proper break-in with quality valve-train oil ensures maximum longevity. The 5.27-pound pair ships securely, ready for inspection before pressing into your cylinder head. Verify OEM part compatibility and cam lift specifications before installation to confirm proper preload and valve clearance.
