Mopar V8 Hydraulic Lifter

The Mopar V8 Hydraulic Lifter (Part Number 822-1) is an essential component for maintaining proper valve train function in classic and modern Mopar V8 engines. Hydraulic lifters are crucial for any engine builder or enthusiast looking to restore, upgrade, or rebuild a Chrysler, Dodge, or Plymouth V8—whether for a street rod, muscle car restoration, or high-performance application.

This lifter automatically adjusts to compensate for engine wear and thermal expansion, eliminating the need for manual valve adjustments and ensuring consistent valve clearance throughout the engine's operating range. The hydraulic lifter design fills with engine oil under pressure, creating a self-adjusting cushion that absorbs shock loads from the cam lobe while keeping the rocker arm in firm contact with the valve stem. This minimizes valve noise, reduces wear on the cam and pushrods, and maintains optimal valve timing without manual adjustment.

Mechanics and engine builders rely on Mopar hydraulic lifters when replacing worn or damaged stock lifters or when installing a new camshaft that demands precise oil pressure management. The compact 3.6 x 1 x 4 inch profile ensures OEM fitment in Mopar engine blocks, making it a reliable choice for both stock-style rebuilds and performance cam swaps.
