COMP Cams XD-A Pushrods

COMP Cams's XD-A pushrods offer a game-changing method for accurately setting lash or pre-load while using non-adjustable-style rockers. These patent-pending pushrods incorporate a top section that slides 2 in. inside a wider bottom section, with one or two shims captured in-between. Proven to 9,000-plus rpm in solid roller LS applications, the system provides a 90 percent increase in bending stiffness for enhanced valvetrain stability. It also allows for lightening of a rocker arm system by 30-plus grams on the backside by removing the adjuster and required support area for threads and seating. The use of lighter rockers with XD-A adjustable pushrods allow higher rpm to be achieved by creating a much more dynamically stable valvetrain system. COMP Cam XD-A pushrods are designed especially for engines with low-mass rocker arms and a light valvetrain with drop-in fitment in LS engines. They can be adjusted over a range of .172 in. in .004 in. increments with shims. Choose the pushrods with the adjustment range needed for your setup.
