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.)

No more broken rockers! BTR rocker arms are designed to provide superior movement of inertia, compared to roller tip rockers, for max RPM. Their all-new 1.7 ratio drop-in design is perfect for cathedral port and square port (exhaust only), but will also work on the exhaust side of the L92/LS3 head. Constructed of bare steel, these BTR rocker arms are 46 percent stronger than stock Chevrolet rockers in FEA analysis--and feature an extended tip design that will allow for higher valve lift and improved valve tip durability.

OEM LS rocker arms are prone to failure, which can result in needle bearings being dispersed through the engine. Smith Brothers suggests replacing the factory needle bearings with solid bronze trunnion bushings that promote even wear and disperse valve spring load evenly. This trunnion upgrade also allows for 360 degree rotation and eliminates the travel stops (which create problems with higher lift camshafts) in the original OE rocker design.

Sealed Power engine assembly prelubes have been proven effective by more than 30 years of use on the assembly lines of U.S. car, truck, and off-road engine manufacturers. They are formulated especially for prelubrication of camshaft lobes and lifters (mechanical and hydraulic) prior to engine oil circulation. Also recommended for bearings, valve stems, rocker arms, push rod tips, and other metal-to-metal contact areas within the engine. Prelube increases load-carrying capacity of the engine oil during break-in to prevent scuffing and galling. The prelubes have special additives which withstand the extreme pressures exerted on cams and lifters. These easy flowing petroleum based lubes function as oil additives, which will not affect oil viscosity. They also hold fast to surfaces on which they are applied and won't run off like engine oil, even after prolonged storage time.
