BAM .842″ BBC Roller Lifters – 0.300″ Tall, .180″ Offset (396–572) (Set of 16)

BAM .842″ BBC Roller Lifters – 0.300″ Tall, .180″ Offset

Offset Roller Lifters for Improved Geometry & Clearance in BBC Performance Builds

BAM .842″ roller lifters are engineered for Big Block Chevy (BBC) engines, featuring a .180″ left and right intake offset to improve pushrod clearance and optimize valvetrain geometry. This design is ideal for high-performance applications running aggressive camshaft profiles where proper alignment and reduced side loading are critical.

The 0.300″ tall body increases lifter-to-bore engagement, enhancing stability and reducing deflection under high RPM and high spring pressure conditions. Precision CNC-machined from high-strength materials, these lifters are built to withstand extreme loads while maintaining smooth, consistent operation.
