Zipper’s Pro-Taper Twin Cam®/XL® Pushrods

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. They are constructed from .095” (standard-duty) or .165″ (extreme-duty) wall chrome-moly that is 7/16” diameter at the bottom and middle of the pushrod, tapering to 3/8” at the top to eliminate any chance of rubbing the covers or head. The bottom side features heavy-duty adjusters and the tops have full-radius “Mae West” tips for smooth operation with the highest lift cams. Our testing shows consistent power gains, even with reduced valve spring pressure. When you control pushrod deflection, the valve stays under control for maximum available power!
