BAM Roller Lifters .9050" Oversize – Chrysler R3 48° Block, 1.56" Lifter Bore, 1.93" Pushrod Seat, Bronze Bushing

Key Features:

• .9050" Oversized Diameter – Precision Fit for Custom Mopar Race Applications
• Oversized for engines requiring .9050" lifter diameter to match honed or custom lifter bores.
• Ensures tight lifter-to-bore engagement, improving tracking and stability in extreme race conditions.
• Ideal for custom-machined R3 blocks, where a slightly larger-than-standard lifter is needed.
• 1.56" Lifter Bore Compatibility – Optimized for Strength and Support
• Specifically designed for 1.56" lifter bores, commonly used in Chrysler R3 and Ritter-based race blocks.
• Provides maximum lifter support and bore engagement, reducing deflection under high loads.
• Increases valvetrain stability and improves camshaft-to-lifter interface integrity.
• 48° Lifter Bore Angle – Race Geometry Advantage
• Configuration - O/C
• Enhances valvetrain efficiency, allows for higher RPM, and reduces stress on pushrods and rockers.
• Promotes smoother and more accurate valve motion, essential for race-level performance.
• 1.93" Pushrod Seat Height – Tuned for Custom Rocker Geometry
• Features a 1.93" pushrod seat, ideal for custom cylinder heads, raised runner ports, and shaft rocker systems.
• Helps maintain proper pushrod angles and rocker arm alignment, essential for optimized valvetrain motion.
• Perfect for tall-deck or high-port head combinations found in competitive Mopar builds.
• Bronze Bushing – Smooth, Reliable, and Durable
• Solid bronze bushing offers excellent oil retention, low friction, and high heat tolerance.
• Ideal for endurance racing, drag racing, or any high-RPM application requiring consistent performance.
• Eliminates needle bearing failure risk, offering increased reliability and longer service life.
• Handles extreme spring pressures and aggressive camshaft profiles with ease.
• 0.300" Tall Body – Added Engagement and Strength
• Taller lifter body improves bore engagement, stabilizing lifter movement at high RPM.
• Reduces lifter walk and rotation, contributing to consistent timing and smoother camshaft operation.
• CNC-Machined Billet Steel Construction
• Built from premium billet steel, precision-machined for tight tolerances and long-term strength.
• Heat-treated for maximum wear resistance, even in high-stress environments.
• Designed to handle extreme race demands, including high spring loads and continuous operation.
• Compatible with High-Lift and Fast-Ramp Camshafts
• Optimized for aggressive cam profiles, delivering smooth, precise valve actuation.
• Reduces lifter bore wear and contributes to consistent power delivery across the RPM range.
• Proven Race Performance
• Used in top-tier Mopar racing builds, including drag racing, dirt late models, and road course engines.
• Trusted for longevity, consistency, and performance under the harshest racing conditions.
• Efficient Oil Flow & Pressure Control
• Bronze bushing promotes oil retention and flow, improving component cooling and lubrication.
• Helps maintain stable oil pressure and prevents premature wear or failure.

Applications:

• Designed for Chrysler R3 48° blocks with 1.56" lifter bores requiring .9050" oversize lifters.
• Compatible with 1.93" pushrod seat height, high-lift cams, and custom rocker/valvetrain geometry.
• Ideal for serious race builds, including drag racing, oval track, and endurance Mopar engines.
