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

Key Features:

• .904" Diameter – Precision Engineered for Chrysler R3 Race Blocks
• Designed specifically for Chrysler R3 48° aluminum race blocks (Ritter-style).
• Ensures stable, accurate lifter tracking under extreme spring pressures and high-RPM operation.
• Ideal for drag racing, circle track, road course, and endurance builds.
• 1.56" Lifter Bore – Oversized for Maximum Support
• Built to fit 1.56" lifter bores, providing greater surface contact for increased strength and stability.
• Reduces lifter walk and improves valvetrain alignment, even under aggressive camshaft profiles.
• Enhances reliability in high-horsepower, high-stress race applications.
• 48° Lifter Bore Angle – Optimized Geometry for R3 Blocks
• Matches the 48-degree lifter angle found in Chrysler R3/Ritter blocks.
• Improves pushrod alignment, reduces side loading, and enhances valve timing accuracy.
• Promotes smoother operation and increased valvetrain efficiency.
• 2.03" Pushrod Seat Height – Ideal for Tall-Deck and Raised Port Heads
• Taller pushrod seat designed to accommodate shaft-mounted rocker systems and raised runner heads.
• Helps maintain proper pushrod angle and valvetrain geometry in custom high-performance builds.
• Reduces friction and improves valve control at high RPM.
• Intake Offset .210" Left & Right – Increased Clearance for Race Heads
• Features .210" intake offset on both sides, providing the clearance needed for large intake ports and wide rocker arm layouts.
• Minimizes pushrod interference and improves valve train efficiency and durability.
• Compatible with aggressive high-lift cams and large-port cylinder heads.
• Pushrod Oiling – Reliable Lubrication for Top-End Components
• Delivers pressurized oil through the pushrods, providing vital lubrication to rocker arms and valve tips.
• Ensures consistent top-end lubrication in high-RPM, high-heat environments.
• Reduces wear and helps maintain valvetrain performance over long durations.
• Bronze Bushing – Durable Needle-Free Design
• Equipped with a solid bronze bushing, offering excellent oil retention, low friction, and high-load durability.
• Ideal for race applications where needle bearing failure is a concern.
• Provides smooth operation under extreme spring pressures and cam profiles, extending lifter and camshaft life.
• 0.300" Tall Body – Increased Engagement for Strength and Stability
• Extended lifter body improves lifter-to-bore engagement, reducing lifter walk and promoting smooth operation.
• Enhances overall valvetrain control and consistency.
• CNC-Machined Billet Steel Body – Built for the Demands of Racing
• Machined from premium heat-treated billet steel for strength and wear resistance.
• Manufactured with tight tolerances for superior performance, even in the most demanding racing conditions.

Applications:

• Designed for Chrysler R3 48° (Ritter) small block race engines with 1.56" lifter bores and 2.03" pushrod seat height.
• Ideal for builds using shaft rocker systems, ported heads, and high-lift camshafts.
• Best suited for drag racing, oval track, and high-RPM endurance Mopar applications requiring pushrod oiling and maximum clearance.
