OEM LS rocker arms are prone to failure, which can result in needle bearings being dispersed through the engine. COMP Cams rocker arm trunnion upgrade kit replaces the OEM needle bearings with fully captive bearings that can not separate. 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. Fits all stock LS rocker arms.
