• Built to handle aggressive camshaft profiles and extreme valvetrain loads.
• 1.56" Lifter Bore Compatibility – Oversized for Maximum Contact
• Tailored to fit 1.56" diameter lifter bores, standard in R3 and Ritter-based competition blocks.
• Provides increased lifter-to-bore surface area for improved stability and reduced wear.
• Minimizes lifter deflection and bore distortion at high RPM and pressure.
• Configuration - O/C
• Reduces side loading on the lifter and pushrod, contributing to longer component life.
• Reduces pushrod angles and side loading, improving valve timing accuracy and pushrod alignment.
• Enables higher RPM capability with enhanced valvetrain efficiency and durability.
• 1.93" Pushrod Seat Height – Tuned for Custom Head and Rocker Setups
• Features a 1.93" pushrod seat height, ideal for tall-deck blocks or custom valvetrain layouts.
• Maintains proper rocker arm geometry, pushrod angle, and valve lift accuracy.
• Compatible with aftermarket cylinder heads and shaft-mounted rocker systems.
• Bronze Bushing – Smooth, Durable & Race-Proven
• Equipped with a solid bronze bushing for enhanced oil retention and thermal stability.
• Provides smooth operation under high-load, high-RPM racing conditions.
• Eliminates the risk of needle bearing failure, making it ideal for endurance and competition use.
• Known for its excellent wear resistance and reliable performance in harsh environments.
• 0.300" Tall Body – Increased Engagement for Strength
• Taller body increases lifter-to-bore contact, preventing walk and deflection.
• Ensures consistent camshaft engagement under extreme spring pressures.
• CNC-Machined Billet Steel Body
