ACDelco GM Genuine Parts Valve Lifter Followers

ACDelco GM Genuine Parts valve lifter followers are designed, engineered, and tested to rigorous standards, and are backed by General Motors. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. The valve lifter followers, also known as a tappet or cam follower, play a crucial role in the operation of an engine's valvetrain. Key benefits of these components include precise valve timing to accurately control the opening and closing of the valves, optimizing combustion efficiency, reducing wear on other valvetrain components, and in the case of hydraulic lifters, they automatically compensate for slight variations in valve clearance, leading to smoother operation and less noise.
