Part number is for a pair of rocker arm shafts w/ improved oiling system for B/RB Big Blocks.
Available for both small block and big block applications. Our proprietary oil delivery system improves the efficiency of chryslers interrupted oil supply to the rocker arms. These shafts are hardened to 48-52 rc and finish ground to increase the life and durability of the shafts and rockers. These shafts feature banana grooved oil holes to spread the oil better in the concentrated pressure areas and calibrated hold down holes to better supply oil to the critical areas. Not for use with needle bearing rockers (Do people still use those?). Buy the good ones before the Chinese copy them wrong and screw up your engine! Naturally these work best and live longest with our rocker arms on them.
Thick wall shaft for extra strength. Removable end plug for cleaning.
