Hyd. Roller Lifters - BBM Retro-Fit

The Hyd. Roller Lifters – BBM Retro-Fit from HOWARDS RACING COMPONENTS are designed for builders looking to modernize big-block Mopar engines without the need for a complete cylinder head redesign. These hydraulic roller lifters provide an upgrade from flat-tappet cam profiles, enhancing efficiency and durability while remaining compatible with original or repurposed BBM (big-block Mopar) block and head casting combinations.

By utilizing a bearing roller, these lifters significantly reduce wear and friction compared to traditional flat-tappet designs, leading to extended cam lobe life. The retro-fit design accommodates the geometric differences between original BBM lifter bores and modern roller lifter diameters, ensuring optimal oil circulation, valve train geometry, and lifter stability across various RPM ranges. Engineered with precision tolerances and durable materials, these lifters are suitable for both street cruising and weekend track duty.

Builders and restoration specialists will find these retro-fit lifters particularly beneficial when aiming to preserve the original architecture of big-block Mopar engines while achieving modern performance standards. Whether restoring a classic Dodge, Plymouth, or Chrysler muscle car, or constructing a street engine with vintage aesthetics, these lifters effectively bridge the gap between classic appeal and contemporary engineering.
