• Designed for Chrysler Big Block V8s (383, 400, 426, 440 CID) with Indy aluminum blocks and heads.
• Delivers excellent lifter bore engagement, ensuring stability, tracking, and long-term durability.
• Ideal for high-performance street, strip, and competition engine builds.
• 1.89" Pushrod Seat Height
• Optimized for valvetrain geometry requiring shorter pushrods, especially in Indy head setups.
• Maintains proper rocker arm alignment and valve motion, reducing stress on valvetrain components.
• Helps ensure precise and consistent valve timing in high-RPM environments.
• Configuration - O/C
• On Center, Reduces pushrod deflection and side loading, promoting efficiency and durability.
• Improves valvetrain geometry in aftermarket and high-port head configurations.
• Pushrod Oiling System:
• Sends pressurized oil through the pushrod to lubricate the upper valvetrain (rockers and tips).
• Ensures reliable oil flow at high RPMs, essential for longevity and consistent performance.
• Supports aftermarket rockers and top-end components that depend on pushrod oiling.
• High-Performance Bronze Bushing:
• Durable solid bronze bushing offers excellent oil retention and heat dissipation.
• Withstands extreme loads, RPM, and camshaft profiles without failure.
• Eliminates the risk associated with needle bearings, making it ideal for endurance and race use.
• Provides low-friction, high-reliability lifter operation for aggressive cam setups.
• 0.300" Tall Body Design:
• Enhances lifter-to-bore contact area, reducing deflection and increasing stability.
• Improves camshaft contact and lifter control, essential for high-performance applications.
• CNC-Machined Billet Steel Construction:
• Precision-machined from premium-grade billet steel for extreme strength and consistency.
• Withstands high spring pressures, valvetrain shock, and elevated engine temperatures.
• Ensures long-lasting performance even in the most demanding builds.
• Camshaft Compatibility:
• Perfect for use with high-lift and fast-ramp camshafts in performance or race engines.
• Reduces valvetrain stress while enhancing power delivery and efficiency.
• Race-Proven Durability:
• Proven in drag racing, circle track, endurance, and high-output street builds.
• Handles extreme heat, RPM, and load cycles with unmatched consistency.
• Efficient Oil Control:
• Supports stable oil pressure and proper lubrication in the lifter and cam interface.
• Helps extend component life and minimize wear under stress.

Applications:

• Fits Chrysler BB engines (383–440 CID) using Indy aluminum heads and blocks.
• Built for setups requiring 1.89" pushrod seat height, offset lifter design, and pushrod oiling.
• Ideal for high-lift camshafts, race engines, and high-performance street or strip builds.
