There’s Power in These Pushrods! Admittedly, the weakest link in a Harley® performance engine is the valve train stiffness, or rather the lack of it. These high performance adjustable pushrods add much needed stiffness to the valve train.
Our Pro-Taper pushrods are also available for the professional Evolution® engine builder who wants the stiffest adjustable pushrods available. The weakest link in an adjustable pushrod is the adjuster itself; keeping the pushrod adjuster as short possible helps maintain the highest resistance to deflection. For this reason we offer the Pro-Taper pushrods, sold each, in the fully collapsed lengths listed below so you can order exactly the lengths you need to keep the adjuster extension at a minimum, for maximum rigidity. Pushrods are chrome moly, .095” wall, 7/16” diameter at the bottom tapering to 3/8” at the top with a full radius rocker ball tip. Adjuster thread is 5/16” x 1.250” length, 32 TPI.
Need custom length pushrods? These solid pushrods are made from heat treated .065” wall seamless 3/8” chrome moly tubing and are supplied with full radius “Mae West” tips (drilled for oil flow) for use with the highest lift cams. They are supplied extra-long with one end unfinished, to be custom fitted by the engine builder. Cut, drill end .250”, ream 17/64”, press in tip. Use with adjustable lifters or customize length for hydraulic lifter pre-load. Sold each.
