One of the most common causes of engine failure in the LS engine range is in valve train. When a rocker trunnion or rocker bolt fail the imminent result will be the rocker pushing on the valve retainer and releasing the collets causing the valve to drop. At this point its game over. In most cases this will result a damaged cylinder head, piston and more often than not, a split bore. It can be an expensive exercise trusting the single M8 bolt to keep your rockers aligned. These new rocker shafts from Brian Tooley are the best value upgrade to keep your LS alive. While using your original rockers you will now have five bolts on a common shaft per rocker pair.

BTR LS3 SHAFT ROCKER KIT
Introducing the new BTR Shaft Rocker Kit – The Next Step in the Evolution of LS Rocker Arm Trunnion Kits
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 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 assembly using your existing stock rockers.
