BAM Roller Lifters .904" – Keith Black (KB) HEMI, O/C, Steel DLC Bushing, Non-Pushrod Oiling

Key Features:

• .904" Diameter – Designed for Extreme HEMI Power
• Precision fit for Keith Black (KB) HEMI aluminum race blocks using standard .904" lifter bores.
• Ensures exceptional lifter-to-bore stability, critical in high-horsepower drag racing applications.
• Engineered for use in Top Alcohol, Pro Mod, and Nitro HEMI racing platforms.
• Configuration - O/C
• On Center, lifter body aligns with wide rocker and high-port cylinder head layouts.
• Improves pushrod clearance and angle, reducing side loading and increasing durability.
• Delivers efficient, smooth valve motion with aggressive camshaft profiles.
• Steel DLC Bushing – High-Load, Low-Friction Durability
• Features a solid steel bushing coated with Diamond-Like Carbon (DLC) for maximum wear resistance.
• Provides ultra-low friction, superior to needle bearings, and ideal for high spring pressure and RPM.
• Eliminates bearing failure risks—perfect for the most demanding race-only environments.
• Extends both lifter and camshaft lifespan under extreme conditions.
• Non-Pushrod Oiling – For External Oiling Systems Only
• Manufactured without internal pushrod oiling; designed for engines using external or block-fed lubrication systems.
• Reduces internal complexity and increases strength and reliability.
• Ideal for dry sump systems used in professional-level HEMI builds.
• 0.300" Tall Lifter Body – Maximum Bore Engagement
• Taller body ensures greater contact within the lifter bore for reduced deflection and improved alignment.
• Enhances valvetrain stability during high-RPM operation and violent valve events.
• Ideal for engines running large lift and high-rate camshafts.
• CNC-Machined Billet Steel Construction – Built for Battle
• Made from premium billet steel, heat-treated for unmatched strength and endurance.
• CNC-machined for precision, guaranteeing tight tolerances and consistent performance.
• Designed to withstand intense spring pressures, high cylinder pressures, and prolonged abuse.
• Race-Tested and Proven
• Proven in Top Fuel, Top Alcohol, and high-horsepower HEMI drag racing platforms.
• Built to provide reliable, consistent performance pass after pass.
• A trusted solution for racers requiring uncompromising durability and valvetrain control.

Applications:

• Fits Keith Black (KB) HEMI engines with offset lifter configurations and .904" lifter bores.
• Intended for builds using external lubrication systems only (non-pushrod oiling).
• Ideal for use with shaft rocker systems, high-lift cams, and extreme valvetrain setups.
• Best suited for Top Alcohol, Nitro HEMI, Pro Mod, and other high-output racing builds.
