Mopar V8 Hydraulic Lifters

COMP CAMS 822-16 Mopar V8 Hydraulic Lifters are high-energy flat tappet hydraulic lifters engineered for small block Mopar, B-series, RB-series, and AMC V8 engines. This complete set of 16 lifters delivers the valve lift and timing precision required for aggressive cam profiles while maintaining the reliability of hydraulic actuation. The 0.904-inch outside diameter ensures proper fitment in factory and performance engine blocks across these classic engine families.

Flat tappet hydraulic lifters like these automatically compensate for thermal expansion and valve train wear through internal oil pressure, eliminating the need for frequent manual adjustment. COMP CAMS' high-energy design supports increased spring pressure and lift rates common in performance applications. The hydraulic design reduces valvetrain noise while protecting components from shock loads during aggressive acceleration and deceleration cycles. For engine builders restoring or upgrading vintage Mopar V8s—whether 318, 340, 360 small blocks or 383, 400, 440 big blocks—these lifters provide the foundation for consistent, repeatable performance across the full RPM range.

These lifters are essential when upgrading to a higher-lift or longer-duration cam profile, or when executing a complete top-end rebuild. They're compatible with roller cam conversions when paired with appropriate pushrods and rocker arms. Technicians and hobbyists rebuilding Mopar engines for street performance, bracket racing, or show duty depend on COMP CAMS lifters to maintain the valve event precision that performance cams are engineered to deliver. The complete 16-piece set covers one full engine, simplifying inventory and ensuring matched components throughout the valvetrain.
