Key Features:

  • .904" Diameter – Purpose-Built for BBM Top Alcohol Engines
  • Designed specifically for Big Block Mopar (BBM) platforms in Top Alcohol drag racing.
  • Ensures tight lifter-to-bore fitment, providing reliable camshaft tracking at extreme RPM.
  • Built to withstand the rigors of high-horsepower, high-spring-pressure race engines.
  • Configuration - O/C
  • On Center, body design improves pushrod alignment with wide rocker spacing and raised port cylinder heads.
  • Reduces pushrod angle stress and side loading, enhancing valvetrain efficiency and durability.
  • Supports accurate valve motion under aggressive cam profiles.
  • No Pushrod Oiling – Designed for External Lubrication Systems
  • Specifically built without internal oiling passages, ideal for dry sump or block-fed oiling systems.
  • Reduces internal complexity and eliminates failure points associated with internal pushrod oiling.
  • Preferred setup in professional Top Alcohol engines where external lubrication is precisely controlled.
  • Bronze Bushing – High-Load Needle-Free Durability
  • Features a solid bronze bushing for exceptional oil retention and wear resistance.
  • Eliminates needle bearings—ideal for high-RPM racing where durability and reliability are critical.
  • Delivers smooth, consistent lifter operation, even under extreme heat and load conditions.
  • Trusted by engine builders for long-term performance and reduced lifter/cam wear.
  • 0.300" Tall Lifter Body – Increased Bore Engagement for Stability
  • Extended body design increases contact within the lifter bore, reducing lifter walk and flex.
  • Enhances stability at high RPM and under extreme spring pressures, ensuring consistent cam contact.
  • Supports valvetrain rigidity and longevity.
  • CNC-Machined from Premium Billet Steel – Built for the Strip
  • Machined from heat-treated billet steel for exceptional strength and wear resistance.
  • Precision CNC tolerances ensure perfect lifter function and repeatable performance.
  • Engineered to thrive in high-load, high-stress drag racing environments.
  • Top Alcohol Race Proven – Professional Grade Component
  • Developed for Top Alcohol drag racing, where lifter reliability is mission-critical.
  • Proven in engines producing massive horsepower and sustaining extreme RPMs.
  • Built for consistency, power delivery, and zero-compromise performance.

Applications:

  • Designed for Big Block Mopar (BBM) Top Alcohol engines using offset lifter configurations.
  • Intended for builds not using pushrod oiling, and compatible with external or block-based lubrication systems.
  • Ideal for use with aggressive camshafts, shaft rocker systems, and high-spring-pressure setups.
  • Trusted in NHRA Top Alcohol, Pro Mod, and other professional drag racing environments.
