The BTR shaft rocker system significantly reduces that deflection when using stock rocker arm mounting, thereby improving performance and durability. This kit features technology typically only found in high-end shaft rocker systems. The shaft rocker system consists of a billet steel stand equipped with four shafts per cylinder head, fasteners and bearings. The shafts are made from genuine 52100 bearing steel. Each pair of rockers has five fasteners mounting them to the rocker stand compared to the traditional single bolt per rocker configuration. During the development of this system, both aluminum and steel stands were tested - steel reigned supreme. The new BTR shaft rocker kit is ready for installation, already pre-assembled with high strength BTR rocker arm bodies. This updated V2 version of the shaft rocker kit features a shim design for easier assembly compared to snap rings and higher strength. - All new 1.7 ratio drop-in design rocker arm bodies - Extended tip design allows for higher valve lift and improved valve tip durability. - Superior Moment of Inertia compared to roller tip rockers for maximum RPM capability.
