T&D Machine Shaft Mount Rocker Arms
T&D Machine Shaft Mounted Rocker Arm Systems are specifically engi- neered for BB Ford aftermarket heads listed below. T&D rockers are made from 2024 aluminum for high tensile and yield strength. T&D rocker arms have an oil passage to channel pressurized oil from the push rod cup to the shaft bearings, and then to the roller tip. Large diameter shafts are made from 4130 steel, deep case hardened and tempered for maximum wear resistance and strength. T&D rocker arm systems are engineered for high spring pressures and higher engine RPMs.
