XD-A™ Adjustable Pushrod Shim Kit by COMP Cams®. COMP Cams introduces a game-changing method for accurately setting lash or pre-load while using non-adjustable-style rockers. The patent-pending XD-A™ Adjustable Pushrods incorporate a top section that slides two inches 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 valve train stability.
