Brian Tooley Racing BTR BTRSRKRFMKIT Features:
Performance-minded engine builders know there is an inherent issue with valve train deflection when using stock rocker arm mounting in Chevrolet Gen III-IV-cylinder heads. The new BTR shaft rocker system significantly reduces that deflection thereby improving performance and durability. This kit features technology typically only found in high-end shaft rocker systems. The shafts are made from genuine 52100 bearing steel.
