Performance-minded engine builders know there's an inherent issue with valvetrain deflection when using stock rocker arm mounting in Chevrolet Gen III-IV-cylinder heads. BTR LS shaft rocker kits are designed to significantly reduce deflection, thereby improving both performance and durability. Each kit features technology typically only found in high-end shaft rocker systems. These shaft rocker systems consist 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. These shaft rocker kits are ready for assembly using your existing stock rockers. (Rocker arm shafts are also available individually.)
