Our premium pushrods are for using adjustable or roller rocker arms in a Mopar Big Block engine. These are made from aircraft quality 4130 alloy 3/8" seamless tubing with a .062 wall thickness. These are supplied in the overall length of 8.905" long. These MUST be used with adjustable or roller rockers, most of which require these type of pushrods which have a "cup" on one end and a standard type "ball" on the other end. These feature a 3/8" diameter ball on the bottom, and the cup on top is designed for a 5/16" diameter ball on the underside of the rocker adjuster.
PLEASE NOTE: THESE ARE NON RETURNABLE. YOU MUST CHECK YOUR REQUIRED LENGTH FIRST WITH A CHECKING TOOL.
Length measurements listed for ball/cup type pushrods are to the TOP of the cup, or the "overall" length of the pushrod. If you are measuring to the bottom of the ball end of the rocker adjuster, you must subtract the depth of the cup (about .150") from our "overall length" measurement.
