Dual Taper Pushrods from COMP Cams feature a .125'' wall and tapered design for high-strength and lightweight construction. Constructed from a special steel alloy, Dual Taper Pushrods utilize a 210 radius rather than standard 180 radius, which makes them perfect for rocker arms that feature cup type adjusters and applications that demand pushrods with more load bearing surface. The lifter end of the pushrod utilizes the standard 3/8'' 180 ball end. All Dual Taper Pushrods are finished with laser-etched length and part numbers for easy identification. - Dual tapered 3/8'' (diameter at ends) to 7/16'' (diameter in center) for strength and lightweight construction. - Constructed with special, high-strength steel alloy. - Utilize a 210 tip at pushrod end for increased load bearing surface.
