Hyd. Roller Lifters - BBC Retro-Fit (2)

The Hydraulic Roller Lifters BBC Retro-Fit (2) by HOWARDS RACING COMPONENTS are designed for big block Chevy engine builders who need reliable hydraulic roller actuation for both street and strip applications. These lifters are a retrofit solution that allows for easy installation into existing BBC engine blocks without requiring extensive modifications.

Featuring a 0.842-inch outer diameter, these hydraulic roller lifters provide consistent valve train geometry and reduced friction compared to traditional flat-tappet designs. The link bar configuration ensures synchronized lifter action during high-RPM operation, which is crucial for maintaining valve timing accuracy and minimizing the risk of valve float in modified big block applications.

These lifters are ideal for builders upgrading street-driven or bracket-racing big block Chevys where compatibility with existing components is essential. Proper verification of lifter bore clearance and camshaft clearance is necessary during installation to prevent any contact during full valve lift.
