For GM Lifters
Hydraulic roller lifters are often paired with high-performance vehicles, a hydraulic lifter creating the lift effect which helps to absorb shock. They eliminate the need for periodic adjustments by maintaining zero clearance when the engine is running. Since lifters run at zero lash noise is reduced from that generated by a purely mechanical valve train. Thermal expansion/contraction and wear is continuously compensated for.
