Hyd. Roller Lifters - SBM Retro-Fit

The Hydraulic Roller Lifters - SBM Retro-Fit from HOWARDS RACING COMPONENTS is a street-series upgrade designed for small block Mopar engines requiring reliable valve actuation with modern hydraulic roller technology. This 16-piece lifter set retrofits into existing engine blocks, eliminating the complexity of cam changes while delivering the smooth, efficient operation that enthusiasts demand. Hydraulic roller lifters are essential for builders seeking to maintain or improve upon original engine geometry without sacrificing performance or durability.

These lifters feature a 0.904-inch outer diameter and incorporate a link-bar design that maintains precise valve train geometry throughout the RPM range. The hydraulic mechanism automatically compensates for thermal expansion and mechanical wear, reducing valvetrain noise and extending component life compared to mechanical alternatives. HOWARDS RACING COMPONENTS engineered this retrofit specifically for small block Mopar platforms, ensuring proper bore fit, oil gallery compatibility, and cam lobe engagement without modification to the block or cylinder head.

Small block Mopar restorers, street engine builders, and vintage muscle car enthusiasts benefit most from this retrofit solution, which allows upgraded valve control on original or stock-based engine combinations. Installation requires no special tools or machine work—the lifters drop into standard lifter bores with the included link-bar assembly. Whether you're building a weekend cruiser or refreshing a classic engine, this complete 16-piece set provides everything needed for immediate installation and reliable long-term service.
