BAM Roller Lifters .904" – Chrysler R3 48° (Ritter) Block, 1.56" Lifter Bore, 2.03" Pushrod Seat, Intake Offset .210" Left & Right, Pushrod Oiling, Steel DLC Bushing

Key Features:

• .904" Diameter – High-Performance Fit for Chrysler R3 Racing Engines
• Precision-engineered for Chrysler R3 48° aluminum blocks (Ritter-style).
• Ensures accurate camshaft tracking and lifter stability at high RPM and extreme valve spring pressures.
• Designed for use in drag racing, circle track, and endurance applications.
• 1.56" Lifter Bore – Enhanced Bore Stability
• Fits oversized 1.56" lifter bores, standard in Ritter and R3-based race blocks.
• Provides increased surface contact, reducing lifter deflection and walk under load.
• Delivers superior valvetrain control and durability in high-stress conditions.
• 48° Lifter Bore Angle – Optimized for Race Geometry
• Matches the 48-degree lifter layout of Chrysler R3 blocks, improving pushrod alignment.
• Reduces side loading and enhances valve timing precision and valvetrain efficiency.
• Ideal for builds using shaft-mounted rockers and aggressive cam profiles.
• 2.03" Pushrod Seat Height – Supports Tall Deck & Custom Rocker Setups
• Taller pushrod seat height allows for custom valvetrain geometry with raised intake ports or tall heads.
• Maintains proper rocker arm alignment and pushrod angle, reducing friction and increasing stability.
• Perfect for shaft rocker systems and raised runner heads.
• Intake Offset .210" Left & Right – Maximum Clearance & Flow
• .210" intake offset on both sides provides ample clearance for larger intake ports and wide rocker arm spacing.
• Minimizes pushrod interference and side loading, optimizing valve actuation and airflow.
• Supports aggressive cylinder head designs and high-lift camshafts.
• Steel DLC Bushing – Ultra-Durable Needle-Free Solution
• Features a solid steel bushing with Diamond-Like Carbon (DLC) coating for superior wear resistance.
• Provides ultra-low friction operation and high load capacity for extreme racing conditions.
• Eliminates needle bearing failures, making it ideal for high-RPM, high-pressure valvetrain systems.
• Maintains performance in high-heat and long-duration environments.
• Pushrod Oiling – Critical for Top-End Lubrication
• Supplies pressurized oil through the pushrods to rocker arms and upper valvetrain components.
• Ensures consistent lubrication during high-RPM operation, preventing wear and heat damage.
• Ideal for engines using roller rockers and high-lift cams.
• 0.300" Tall Lifter Body – Increased Bore Engagement
• Taller body design increases lifter-to-bore contact, enhancing stability and reducing deflection.
• Helps maintain consistent camshaft contact and smooth lifter travel under high-load conditions.
• CNC-Machined Billet Steel Construction
• Precision machined from premium billet steel, heat-treated for maximum strength and durability.
• Designed with tight tolerances for smooth operation and long-term reliability in racing environments.

Applications:

• Built for Chrysler R3 48° (Ritter) race blocks with 1.56" lifter bores and 2.03" pushrod seat height.
• Ideal for use with shaft-mounted rocker systems, raised port heads, and high-lift camshaft profiles.
• Perfect for drag racing, oval track, road racing, and endurance builds requiring pushrod oiling and maximum lifter stability.
