Zipper’s Custom Length Pro-Taper Pushrods for XL, Twin Cam and EVO Engines

Our Pro-Taper pushrods are also available for the professional 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.

Note – Pushrods are sold each. Depending on your tappets and pushrod tube length the length of the lower adjuster may not be ideal for ease of adjustment.
