FEULING OIL PUMP CORP. Adjustable HP+ Pushrods - Harley-Davidson 1984-2000 - Evolution 4077

• Maintain maximum valve lift!
• Increased stiffness and column rigidity maximizing valve-train stability, increasing engine RPM horsepower and torque output.
• Adjustable pushrods are 3/8 4130 chrome moly tube and use a minimal adjustment parameter eliminating flex and loss of valve train-stability problems associated with most adjustable pushrods.
• Individual length intake & exhaust pushrods keep the adjustment extension to a minimum
• Designed to exceed the needs of performance engines using larger lift camshafts and high spring pressures, while maintaining proper and critical oil flow to top end valve gear.
• HP+ pushrods have 24 threads per inch adjustment, super strength single jam nut lock system, wall thickness 0.120
• RACE SERIES have 24 threads per inch with 0.145 wall thickness - recommended when extreme valve-spring pressures are used.
• Designed for use with hydraulic or solid lifters and street or race engines
• HP+ and RACE SERIES pushrods require removal of rocker covers and rocker arm supports, FEULING QUICK INSTALL rods can be installed without removing the rocker covers, arms and supports
• FEULING HP+ and RACE SERIES pushrods can be used with the factory pushrod tubes.
• Made in the U.S.A.

NOTE: HP+ and RACE SERIES adjustable pushrods can be adjusted 0.225 over stock length to accommodate longer cylinders and smaller base circle camshafts.
