BAM Roller Lifters .9050" Oversize – Chrysler Big Block V8 383–440, O/C, Pushrod Oiling, Bronze Bushing

Key Features:

• .9050" Oversize Diameter
• Designed for Chrysler Big Block V8 engines (383–440 CID) with oversized or sleeved lifter bores.
• Ideal for performance engine rebuilds where standard .904" lifters no longer provide proper bore fitment.
• Enhances lifter bore engagement and improves valvetrain alignment and rigidity.
• Configuration - O/C
• On Center, Designed for optimal valvetrain alignment in high-performance builds.
• Optimizes valvetrain geometry for better performance and reduced component wear.
• Reduce side loading on lifters and pushrods under high RPM and load.
• Pushrod Oiling Design:
  • Directs oil through the pushrod to the upper valvetrain, ensuring constant rocker and valve tip lubrication.
  • Critical for high-performance valvetrain setups and aftermarket rockers that depend on pushrod oiling.
  • Enhances valvetrain cooling and wear resistance in extreme applications.
• Bronze Bushing Technology:
  • High-performance solid bronze bushing for exceptional oil retention and smooth operation.
  • Withstands high loads and RPMs, extending the lifespan of both lifters and camshaft lobes.
  • More durable and reliable than needle bearings—no risk of bearing failure under extreme stress.
• 0.300" Tall Body Design:
  • Increases lifter-to-bore engagement area, improving overall stability and wear resistance.
  • Reduces valvetrain deflection, maintaining accurate cam timing and lifter travel.
• Precision CNC-Machined Body:
  • Machined from high-quality billet steel to exacting tolerances for consistent lifter function.
  • Provides maximum strength and heat resistance, perfect for aggressive camshaft profiles.
  • Built to handle high spring pressures and severe duty cycles.
• High-Lift Camshaft Compatibility:
  • Designed to work flawlessly with high-lift and aggressive cam profiles.
  • Improves valvetrain efficiency and longevity while maintaining precise valve motion.
• Proven Race Durability:
  • Tested and trusted in drag racing, endurance racing, and high-horsepower street builds.
  • Withstands extreme heat, high RPM, and heavy valvetrain loads with consistent performance.
• Optimized Oil Flow Management:
  • Promotes efficient oil flow to critical areas, reducing wear and extending component life.
  • Helps maintain consistent oil pressure, supporting high-output engine operation.

Applications:

• Compatible with Chrysler BB V8 engines: 383, 400, 413, 426, and 440 CID.
• Ideal for oversized lifter bore blocks, high-performance rebuilds, and racing applications.
• Suitable for use with pushrod oiling systems, aftermarket rockers, and aggressive camshafts.
