BAM Roller Lifters .904" – Chrysler R3 48° Block, 1.56" Lifter Bore, 1.93" Pushrod Seat

Key Features:

• .904" Diameter – Built for Mopar Race Applications
• Designed for use in Chrysler R3 48° race blocks, providing tight lifter-to-bore engagement.
• Ensures consistent lifter tracking at high RPM and under extreme spring pressures.
• Ideal for drag racing, oval track, and high-performance Mopar small block builds.
• 1.56" Lifter Bore Compatibility – Oversized for Stability
• Specifically designed to fit 1.56" diameter lifter bores, common in R3 and other competition blocks.
• Maximizes contact area between lifter and bore, reducing deflection and lifter walk.
• Delivers better valvetrain control and bore integrity, especially with aggressive cam profiles.
• Configuration - O/C
• Reduces side loading on the lifter and pushrod, contributing to longer component life.
• Supports higher RPM operation and more aggressive camshaft ramp rates.
• 1.93" Pushrod Seat Height – Ideal for Custom Valvetrain Layouts
• Designed with a 1.93" pushrod seat height for compatibility with specific rocker stand and pushrod lengths.
• Optimizes valvetrain geometry in R3 block builds with custom cylinder head configurations.
• Maintains correct rocker arm angles for reliable high-lift performance.
• 0.300" Tall Lifter Body – Enhanced Engagement
• Provides increased lifter-to-bore contact, improving lifter tracking at high RPM.
• Reduces the risk of lifter rotation or walk, even under aggressive cam and valve spring combinations.
• CNC-Machined Billet Steel Construction
• Made from premium billet steel, heat-treated for superior strength and wear resistance.
• Machined to precise tolerances to ensure consistent performance and reliability.
• Built to withstand high cylinder pressure and prolonged racing conditions.
• Compatible with High-Lift Camshafts
• Perfectly suited for fast-ramp, high-lift cam profiles, allowing for efficient valve motion and high RPM control.
• Minimizes wear and friction while improving valvetrain responsiveness.
• Race-Tested Durability
• Proven performance in NHRA, circle track, and professional Mopar racing engines.
• Built to survive intense thermal cycles, spring pressures, and high RPM abuse.
• Optimized Oil Flow and Lifespan
• Supports effective lubrication of lifter internals and upper valvetrain components.
• Enhances oil retention and contributes to stable oil pressure across the engine.

Applications:

• Fits Chrysler R3 48° race blocks with 1.56" lifter bores and 1.93" pushrod seat height.
• Ideal for builds with custom rocker geometry, raised runner heads, or specialized Mopar valvetrain setups.
• Designed for racing, high-lift camshaft applications, and high-output small block Mopar engines.
