A genuine GM manufactures the Part Number: 12731971 which stands as a top-quality Arm, Engine Valve Rocker for optimal engine performance in vehicles. Within New this GM part functions as a Direct Replacement component which ensures perfect compatibility with automobile specifications. A critical function in the valve train system of the engine belongs to the rocker arm which takes motion from the pushrod to move both the intake and exhaust valves. The part converts the vertical motion of pushrods into the correct downward position which opens the valves increasing efficiency of the engine. When speeds exceed a certain threshold aluminum becomes the preferred material because it decreases engine weight yet diesel engines demand cast iron or forged carbon steel for improved durability. Engine performance benefits from the camshaft lift enhancement that results from using rocker ratios that measure between 1.5:1 and 1.8:1. The operating range of high-RPM engines requires upgraded fulcrum bearings as a stress management component. A factory warranty from GM supports this part which acts as a crucial component for vehicle engine maintenance through its proven reliability and performance attributes.
