BAM Roller Lifters .904" – Big Block Mopar (BBM) Top Alcohol, O/C, No Pushrod Oiling, Steel DLC Bushing

Key Features:

• .904" Diameter – Optimized for BBM Top Alcohol Race Engines
• Specifically designed for Big Block Mopar (BBM) Top Alcohol applications with standard .904" lifter bores.
• Provides exceptional lifter stability and precise cam tracking under extreme RPM and valve spring loads.
• Built for the demands of professional drag racing environments.
• Configuration - O/C
• On Center, body design enables better pushrod alignment with raised port or wide rocker cylinder heads.
• Reduces side loading on the pushrod, improving valve motion and minimizing wear.
• Enhances valvetrain efficiency, particularly with high-lift camshafts and aggressive profiles.
• No Pushrod Oiling – Simplified, High-Strength Design
• Engineered without internal oiling passages, making it ideal for external oiling systems used in Top Alcohol engines.
• Eliminates potential oil passage failures and reduces internal complexity for maximum reliability.
• Perfect for dry sump or block-fed oil systems common in high-end drag racing builds.
• Steel DLC Bushing – Extreme Durability & Low Friction
• Features a solid steel bushing coated in Diamond-Like Carbon (DLC) for maximum wear resistance.
• Provides ultra-low friction operation, reducing heat and wear in high-load, high-RPM conditions.
• A superior alternative to needle bearings—eliminates bearing failure risk while supporting aggressive cam profiles.
• 0.300" Tall Lifter Body – Increased Stability and Strength
• Extended body length increases lifter-to-bore engagement, reducing deflection and improving valvetrain control.
• Enhances durability during rapid valve events and high-RPM conditions common in drag racing.
• CNC-Machined Billet Steel Construction – Race-Proven Toughness
• Crafted from premium heat-treated billet steel for superior strength and longevity.
• CNC-machined to exact tolerances for precision fitment and consistent performance.
• Designed to handle extreme cylinder pressures and spring loads found in Top Alcohol engines.
• Top Alcohol Race Ready – Built to Win
• Developed specifically for Top Alcohol and other high-horsepower drag racing categories.
• Trusted by top-tier race teams for its bulletproof reliability and performance consistency.
• Designed for zero-failure performance when fractions of a second make the difference.

Applications:

• Ideal for Big Block Mopar (BBM) Top Alcohol race engines using offset lifter configurations.
• Built for use without pushrod oiling, and perfectly suited for external or block oiling systems.
• Designed to withstand the most aggressive camshafts, spring pressures, and RPM levels in drag racing.
• A top choice for NHRA Top Alcohol, Pro Mod, and high-horsepower Mopar builds.
