BAM Roller Lifters .904" – Chrysler R3 48° Block, 1.56" Lifter Bore, 1.93" Pushrod Seat, Pushrod Oiling, Intake Offset .210" Left & Right

Key Features:

• .904" Diameter – Built for Precision in Mopar Race Applications
• Specifically designed for Chrysler R3 48° small block race engines.
• Ensures precise lifter tracking and stable cam contact under extreme RPM and valve spring loads.
• Perfect for drag racing, circle track, and high-performance small block Mopar builds.
• 1.56" Lifter Bore Compatibility – Oversized for Maximum Stability
• Tailored for 1.56" diameter lifter bores, standard in R3 and Ritter-style race blocks.
• Provides maximum surface contact, reducing bore wear and lifter deflection.
• Enhances valvetrain rigidity, especially under aggressive cam profiles and spring pressures.
• 48° Lifter Bore Angle – Optimized Valvetrain Geometry
• Matches the 48° lifter bore angle of Chrysler R3 blocks for improved pushrod alignment.
• Reduces lifter and pushrod side loading, improving valve timing accuracy and durability.
• Supports higher RPM operation with smoother valve motion and improved longevity.
• 1.93" Pushrod Seat Height – Ideal for Custom Rocker and Head Layouts
• Extended pushrod seat height provides proper geometry for tall-deck or raised-runner heads.
• Works with custom rocker arm setups, maintaining correct pushrod length and angle.
• Improves valvetrain motion and reduces stress on pushrods and rockers.
• Intake Offset .210" Left & Right – Maximum Clearance for High-Port Heads
• Features .210" intake offset on both sides to accommodate large intake runners and ported heads.
• Provides extra clearance for shaft rockers and aggressive valvetrain setups.
• Improves pushrod alignment and reduces interference in high-lift builds.
• Pushrod Oiling – Critical for High-RPM Valvetrain Durability
• Supplies pressurized oil through the pushrods, essential for roller rocker systems.
• Enhances top-end lubrication, reducing friction and wear in high-performance camshaft and valvetrain systems.
• Helps maintain oil pressure and cooling at elevated RPMs.
• 0.300" Tall Body Design – Increased Engagement & Support
• Taller body offers more lifter-to-bore contact, reducing lifter walk and maintaining camshaft alignment.
• Supports smooth lifter travel and consistent performance under extreme load conditions.
• CNC-Machined from Premium Billet Steel
• Precision-crafted from heat-treated billet steel for superior strength and wear resistance.
• Machined to tight tolerances for smooth, consistent lifter function and long-lasting reliability.
• Built to handle high valve spring pressures and aggressive camshaft profiles.
• High-Lift Camshaft Compatibility
• Perfect for use with fast-ramp, high-lift camshafts.
• Reduces friction and bore wear while maximizing valvetrain control and efficiency.
• Ideal for race engines operating at 7,000+ RPM.
• Race-Tested Durability
• Proven in top-tier Mopar racing environments, from drag to circle track.
• Built to withstand extreme temperature, pressure, and cycle demands.

Applications:

• Designed for Chrysler R3 48° small block race engines with 1.56" lifter bores and 1.93" pushrod seat height.
• Ideal for builds using raised-port cylinder heads, shaft rocker systems, and aggressive cam profiles.
• Best suited for high-RPM racing, endurance engines, and Mopar competition builds.
