Key Features:

• .904" Diameter – Oversized Strength for High-Performance Builds
• Engineered for Rocket Racing Performance Big Block Oldsmobile applications using .904" lifter bores.
• Larger diameter increases lifter strength and surface area, reducing deflection under extreme valve spring pressures.
• Perfect for serious drag racing, endurance builds, and high-horsepower Olds engines.
• Steel DLC Bushing – Premium Friction & Wear Protection
• Features solid steel bushings with Diamond-Like Carbon (DLC) coating for exceptional durability.
• DLC reduces friction and wear, providing smoother operation and longer lifespan compared to needle bearings.
• Withstands extreme camshaft loads, high RPM, and aggressive ramp rates with quiet, low-friction performance.
• Enhanced oil retention ensures reliable lubrication during extended duty cycles.
• On Center Lifter for Rocket Racing Valve Geometry
• Designed to work with Rocket Racing BB Olds cylinder heads, valvetrain geometry, and shaft rocker systems.
• Maintains precise pushrod alignment and valve timing, critical for high-lift camshaft profiles.
• Supports wide port layouts and custom setups for modern Oldsmobile race builds.
• 0.300" Tall Lifter Body – Enhanced Bore Engagement
• Tall-body design increases contact area between the lifter and lifter bore, reducing lifter walk.
• Improves valvetrain stability, camshaft tracking, and high-RPM reliability.
• Essential for engines with fast-ramp camshafts and extreme valve spring pressures.
• CNC-Machined Billet Steel – Built to Withstand Extreme Loads
• Precision CNC-machined from premium billet steel, then heat-treated for maximum strength and wear resistance.
• Ideal for demanding applications with tight lifter bore clearances and custom block machining.
• Delivers consistent performance under race-winning conditions.
• Race-Proven Design – Trusted by Builders & Racers
• Extensively tested in high-output Rocket Racing Oldsmobile engines across drag strip and endurance platforms.
• Provides reliable operation in engines exceeding 7,000+ RPM, high spring loads, and aggressive camshaft timing.
• Rebuildable design allows for long-term serviceability and customization.

Applications:

• Designed for Rocket Racing Performance Big Block Oldsmobile V8s using .904" lifter bores.
• Ideal for engines with shaft rocker systems, aftermarket heads, and high-lift camshafts.
• Suited for drag racing, circle track, performance street builds, and custom Oldsmobile race engines.
