Key Features:

• .9050" Oversize Diameter
• Designed for Chrysler Big Block V8 engines (383–440 CID) with worn, sleeved, or oversized lifter bores.
• Provides enhanced bore engagement, increased strength, and improved lifter stability under high load.
• Perfect for performance rebuilds, precision engine builds, and oversized bore applications.
• Configuration - O/C
• On Center, Designed for optimal valvetrain alignment in high-performance builds.
• Reduces valvetrain stress, improving long-term performance and efficiency.
• Pushrod Oiling System:
  • Delivers pressurized oil through the pushrod to the rocker arms and top end of the engine.
  • Ensures continuous lubrication to reduce heat and wear, especially in high-RPM or endurance use.
  • Essential for modern aftermarket valvetrain setups where upper-end oiling is required.
• Steel DLC (Diamond-Like Carbon) Bushing:
  • Provides ultra-low friction and extreme wear resistance, outperforming traditional needle bearings.
  • Eliminates risk of needle bearing failure, enhancing reliability in demanding applications.
  • Withstands extreme loads and high valve spring pressures, ideal for racing and aggressive cam profiles.
  • Superior oil retention increases durability and reduces heat under stress.
• 0.300" Tall Body Design:
  • Increases lifter-to-bore surface contact, reducing deflection and maintaining consistent cam contact.
  • Promotes valvetrain stability, particularly in high-RPM or high-horsepower setups.
• Precision CNC-Machined from Premium Billet Steel:
  • High-strength material provides maximum fatigue resistance and dimensional accuracy.
  • Precision machining ensures smooth travel, quiet operation, and consistent lifter performance.
  • Designed to work with high-lift camshafts and aftermarket valvetrain components.
• Race-Tested Durability:
  • Proven in drag racing, endurance racing, and high-horsepower street/strip builds.
  • Handles extreme temperatures, RPMs, and dynamic engine loads without compromise.
• Enhanced Oil Management:
  • Optimized for efficient oil flow and distribution, helping to maintain pressure and minimize wear.
  • Helps extend lifter, camshaft, and overall engine life under demanding conditions

Applications:

• Fits Chrysler Big Block V8 engines: 383, 400, 413, 426, and 440 CID.
• Ideal for oversized bore engines, performance rebuilds, and race applications.
