• 0.300" Tall Body – Improved Bore Engagement and Stability
• Taller lifter body design enhances lifter-to-bore contact area, improving lifter tracking.
• Reduces lifter walk, deflection, and valve timing variance under extreme RPM and load.
• Increases control and reliability in competition-grade applications.
• CNC-Machined Billet Steel – Built for Extreme Performance
• Made from premium billet steel, CNC-machined to exact tolerances for consistent operation.
• Heat-treated for maximum strength, wear resistance, and lifespan under heavy use.
• Capable of enduring fast ramp camshafts and endurance-style abuse without failure.
• Proven in High-Output Oldsmobile Builds
• Trusted by professional engine builders in drag racing, circle track, and performance street applications.
• Developed to withstand the demanding conditions of high-RPM Oldsmobile-based powerplants.
• Delivers consistent oiling, precision lifter action, and race-proven reliability.

Applications:

• Designed for Rocket Racing Performance Big Block Oldsmobile V8 engines using .842" lifter bores.
