About this product

GM Genuine Parts Engine Valve Lifters are designed, engineered, and tested to rigorous standards, and are backed by General Motors. The valve lifter is the unit that makes contact with the push rod or valve stem and the camshaft. It rides on the camshaft. When the cam lobes push it upwards, it operates a rocker arm to open the valve. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
