Upgrade the valvetrain of your early Mopar Hemi engine with the Howards Racing Components 91731 Performance Hydraulic Flat Tappet Lifter Set. Designed for Mopar Gen-I Hemi applications, this complete set supports 331, 354, and 392 cubic-inch engines and includes 16 lifters for a full engine installation. The hydraulic flat tappet design provides reliable valve-train operation without requiring routine lash adjustment, making it a practical choice for performance street and traditional engine builds.
The lifters are engineered with a performance-oriented design and a standard Mopar early Hemi fitment profile. Their construction is intended to support consistent contact between the camshaft and lifter while helping maintain stable valve motion through the operating range. The hydraulic mechanism automatically compensates for normal valve-train expansion, contributing to quieter operation and dependable performance when used with compatible camshaft, pushrod, and valve-train components.

Part number 91731 is supplied as a complete set of 16 hydraulic flat tappet lifters, making it well suited for engine refreshes, camshaft upgrades, and complete early Hemi valve-train installations. Always verify camshaft compatibility, installation procedures, oiling requirements, and break-in recommendations before assembly to help achieve proper lifter and camshaft service life.
