BAM .842" BBC Roller Lifters – 0.300" Tall, On-Center

High-Strength Roller Lifters for Big Block Chevy Performance Builds

BAM .842" roller lifters are designed specifically for Big Block Chevy (BBC) engines, delivering improved stability, durability, and valvetrain control for high-performance applications. Featuring a 0.300" tall body design, these lifters increase lifter-to-bore engagement and reduce deflection under high load and high-RPM conditions.

The on-center pushrod configuration maintains proper valvetrain geometry while supporting aggressive camshaft profiles.
