BAM Roller Lifters .9050" Oversize – Chrysler R3 48° Block, 1.56" Lifter Bore, 1.93" Pushrod Seat, Pushrod Oiling, Intake Offset .210" Left & Right

Key Features:

• .9050" Oversize Diameter – Precision Fit for Custom Mopar Race Blocks
• Designed for R3 and Ritter-style Chrysler small block race engines requiring oversize lifters.
• Oversized to .9050" for tight bore fitment in honed or custom-machined lifter bores.
• Ensures maximum lifter stability, superior tracking, and minimized bore wear at high RPM.
• 1.56" Lifter Bore Compatibility – Built for Strength and Stability
• Fits 1.56" diameter lifter bores, standard in many Chrysler R3 competition blocks.
• Provides increased lifter-to-bore surface area, reducing deflection and lifter walk.
• Enhances valvetrain integrity in engines with aggressive camshaft profiles and extreme loads.
• 48° Lifter Bore Angle – Optimized Race Geometry
• Configured to the 48-degree lifter bore angle of Chrysler R3 blocks.
• Improves pushrod alignment, reduces side loading, and ensures accurate valve timing.
• Promotes smoother motion and increased valvetrain durability at elevated RPM.
• 1.93" Pushrod Seat Height – Custom Fit for Aftermarket Heads & Rockers
• Features a 1.93" pushrod seat height, ideal for use with shaft-mounted rocker systems and tall-deck blocks.
• Maintains optimal pushrod angle and valvetrain geometry, improving valve motion and longevity.
• Supports compatibility with custom cylinder head and valvetrain combinations.
• Intake Offset .210" Left & Right – Maximum Clearance for High-Performance Heads
• Includes .210" intake offset on both sides, providing additional clearance for ported heads, raised runners, and wide rocker configurations.
• Allows room for larger pushrod passages while reducing interference and enhancing pushrod travel.
• Minimizes pushrod side loading, contributing to smoother and more efficient valve actuation.
• Pushrod Oiling – Essential for Top-End Lubrication
• Delivers pressurized oil through the pushrods to the rocker arms and valvetrain components.
• Enhances lubrication for roller rockers and high-lift cam profiles, reducing wear and heat generation.
• Promotes consistent oil delivery at high RPM and elevated temperatures.
• 0.300" Tall Lifter Body – Increased Engagement for Strength
• Extended body length offers deeper lifter bore engagement, reducing deflection under extreme load.
• Provides consistent camshaft contact and lifter travel, especially at high RPMs.
• Supports smooth valvetrain motion during rapid valve events.
• CNC-Machined from Premium Billet Steel
• Crafted from high-strength billet steel, heat-treated for exceptional wear resistance and reliability.
• Precision-machined to tight tolerances for smooth travel, accurate function, and long-term performance.
• Engineered to endure high spring pressures, aggressive camshaft ramps, and race-level abuse.
• Race-Tested & Proven Durability
• Trusted by engine builders in drag racing, circle track, road racing, and endurance motorsports.
• Built for extreme environments where valvetrain control and reliability are critical.

Applications:

• Fits Chrysler R3 48° small block race engines with 1.56" lifter bores requiring .9050" oversize lifters.
• Optimized for 1.93" pushrod seat height, shaft rockers, high-lift cams, and ported head combinations.
• Ideal for high-horsepower, high-RPM racing applications, including drag racing, oval track, and road course builds.
