BAM Roller Lifters .937" – Chrysler R3 48° | 1.56" Lifter Bore | 2.03" Pushrod Seat | Intake Offset .210" L/R | Steel DLC Bushing

Key Features:

• .937" Diameter – Race-Ready Precision for Chrysler R3 Platforms
• Specifically engineered for Chrysler R3 48-degree lifter angle blocks with .937" lifter bores.
• Ideal for high-performance and professional drag racing engines requiring maximum valvetrain stability and strength.
• Compatible with 426 HEMI-based R3 race engines, commonly used in Top Alcohol, Pro Mod, and Nitro builds.
• 1.56" Lifter Bore – Enhanced Support for Extreme Loads
• Designed to fit the wider 1.56" lifter bore found in R3 blocks, providing superior lifter-to-bore engagement.
• Reduces lifter walk and deflection at high RPM and high valve spring pressures.
• Enhances valvetrain integrity under the most demanding race conditions.
• 2.03" Pushrod Seat – Optimized Geometry for Long Pushrods
• Higher 2.03" pushrod seat location aligns properly with long pushrod setups, improving rocker arm angle and motion.
• Enhances valvetrain efficiency and reduces wear on rockers, pushrods, and valve tips.
• Perfect for raised-port or high-runner cylinder heads requiring increased pushrod length.
• Intake Offset .210" Left & Right – Improved Pushrod Clearance
• Intake lifters feature a .210" offset (both left and right) for maximum pushrod clearance in large intake port heads.
• Corrects for tight pushrod angles found in wide runner and high-port designs, improving valvetrain geometry.
• Minimizes side-loading, helping maintain consistent valve motion and reducing long-term wear.
• Steel DLC Bushing – Premium Performance & Longevity
• Outfitted with solid steel bushings coated in Diamond-Like Carbon (DLC) for ultra-low friction and superior wear resistance.
• DLC coating provides excellent oil retention, reduces friction, and extends component life under extreme conditions.
• Eliminates the risk of failure common with needle bearings in high-load, high-RPM environments.
• 0.300" Tall Body – Superior Lifter Bore Engagement
• Extended body height offers increased lifters-to-bore contact, reducing distortion and improving tracking accuracy.
• Enhances performance consistency under high RPM and aggressive spring pressures.
• Ideal for engines with high-lift cams and fast ramp rates.
• CNC-Machined Billet Steel Construction – Built for Maximum Strength
• Machined from premium billet steel, then heat-treated for unbeatable strength and dimensional stability.
• Engineered with precision to tight tolerances for seamless fit, quiet operation, and repeatable lifter action.
• Designed to withstand the demands of extreme camshaft profiles and 2,000+ HP engine builds.
• Race-Tested & Proven – Trusted by Professionals
• Purpose-built for elite-level racing including NHRA Top Alcohol, Nitro HEMI, and high-end Mopar drag builds.
• Proven to perform reliably under extreme temperatures, loads, and RPM conditions.
• A go-to choice for engine builders and racers demanding precision, reliability, and performance.

Applications:

• Fits Chrysler R3 48° blocks with .937" lifter bores, 1.56" lifter bore diameter, and 2.03" pushrod seat height.
• Designed for high-port intake heads, long pushrod setups, and shaft rocker systems.
• Compatible with aggressive camshafts, high-spring-pressure valvetrain systems, and professional drag racing engines.
• Ideal for 426 HEMI-based racing engines in Top Alcohol, Pro Mod, and Nitro competition.
