The engine valve train depends heavily on rocker arms since they link pushrod motion to the opening and closing of intake and exhaust valves. The rocker arm successfully transforms vertical pushrod movement into proper opening force through its stamped steel or aluminum design. For high-RPM conditions manufacturers prefer lightweight aluminum over cast iron and forged carbon steel since aluminum provides better performance. Engine performance enhancement results from the rocker ratio which operates between 1.5:1 and 1.8:1 to multiply camshaft lift amplitude. High-RPM engines utilize upgraded fulcrum bearings which guarantee the effectiveness of rocker arm systems when operating under stress. This automotive component comes with a GM factory warranty which provides both dependability and performance characteristics to guide vehicle upkeep needs.
