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

Key Features:

• .904" Diameter – Race-Optimized for Mopar Small Block Applications
• Designed for Chrysler R3 48° aluminum blocks (Ritter-style) with .904" lifter specification.
• Provides exceptional lifter stability and camshaft engagement under extreme RPM and high spring loads.
• Perfect for drag racing, circle track, and high-horsepower competition builds.
• 1.56" Lifter Bore – Enhanced Bore Contact for Maximum Stability
• Tailored for oversized 1.56" lifter bores found in R3 and Ritter race blocks.
• Increases bore-to-lifter surface area, reducing lifter walk and improving alignment under stress.
• Built to maintain consistent valvetrain geometry at high engine speeds.
• 48° Lifter Bore Angle – Precise Geometry for R3/Ritter Platforms
• Matches the 48-degree lifter angle of R3 blocks, improving pushrod alignment and reducing side loading.
• Ensures accurate valve timing, smoother lifter operation, and enhanced component longevity.
• Ideal for engines with aggressive cam profiles and tight rocker clearances.
• 2.03" Pushrod Seat Height – Perfect for Tall Cylinder Head/Rocker Systems
• Provides added height for custom valvetrain setups, including shaft-mounted rocker systems and tall-deck heads.
• Maintains proper pushrod angle and rocker arm geometry, reducing friction and improving lift consistency.
• Allows for greater valve train tuning flexibility in high-performance Mopar applications.
• Intake Offset .210" Left & Right – Optimized Clearance for Race Heads
• Features .210" intake offset on both sides, allowing clearance for wide intake ports, ported heads, and larger rocker assemblies.
• Reduces pushrod interference while improving valvetrain alignment and airflow potential.
• Ideal for use with high-lift camshafts, raised runners, and wide rocker spacing.
• Pushrod Oiling – Critical for Top-End Lubrication
• Delivers pressurized oil directly through the pushrods, keeping rocker arms and valve tips lubricated.
• Ensures consistent lubrication under high-RPM operation and minimizes wear on upper valvetrain components.
• Designed to support roller rocker systems and aggressive valve actuation.
• 0.300" Tall Lifter Body – Increased Bore Engagement & Rigidity
• Taller design allows more lifter body engagement within the bore, improving alignment and reducing deflection.
• Supports consistent valvetrain performance in high-stress racing environments.
• CNC-Machined Billet Steel Construction
• Precision-machined from heat-treated billet steel for strength, wear resistance, and dimensional accuracy.
• Ensures tight lifter tolerances, reliable cam tracking, and consistent oil control.
• High-Lift & High-RPM Ready
• Designed for use with fast-ramp, high-lift camshafts in race applications.
• Reduces lifter wear and helps maintain valve timing consistency at elevated RPMs.
• Compatible with high spring pressures and endurance engine configurations.

Applications:

• Built for Chrysler R3 48° (Ritter) small block race engines with 1.56" lifter bores and 2.03" pushrod seat height.
• Ideal for engines requiring .210" intake offset, shaft rockers, and aggressive ported heads.
• Perfect for drag racing, circle track, road racing, and endurance Mopar builds utilizing pushrod oiling.
