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