Feuling, adjustable chromoly Race Series pushrods

Heat-treated 4130 chromoly pushrods with extra-thin 3/8" (9.53mm) tapered end and 3/8-24 nut with 24 threads per inch. With .145" wall thickness (extra thick), recommended when extreme valve spring pressures are used. Manufactured with precision concentricity. Individual intake and exhaust pushrod lengths minimise adjustment extension to increase rigidity and stability, achieving maximum valve lift under high RPM loads. The pushrods can be set 0.225" longer than stock to accommodate longer cylinders and camshafts with a smaller base circle.
• They maintain maximum valve lift!
• Greater stiffness and stability of the column, maximising valve train stability, increasing power (horsepower) and torque at higher RPM.
• The 3/8" tapered adjustable chrome-molybdenum 4130 pushrods use a minimal adjustment parameter, eliminating the flexing and valve train stability loss issues associated with most adjustable pushrods.
• Individual intake and exhaust lengths keep the tuning spread to a minimum.
• Designed to exceed the needs of high-performance engines using higher lift camshafts and high spring pressures, whilst maintaining proper and critical oil flow to the upper components of the valve train.
• The Race Series pushrods have 24 threads per inch and a 0.145" wall thickness - recommended when extreme valve spring pressures are used.
• Designed for use with hydraulic or mechanical tappets and street or racing engines.
• HP+ and RACE SERIES pushrods require removal of the rocker covers and rocker arm supports.
• FEULING pushrods can be used with the factory pushrod tubes.
• The pushrods can be adjusted 0.225" longer than stock to suit longer cylinders and camshafts with a smaller base circle.
• Manufactured in the USA.
