A game-changing method for accurately setting lash or pre-load while using non-adjustable style rockers. The patent-pending system incorporates a smaller top section that slides two inches deep inside a larger bottom section. Length can then be adjusted in .004" increments with available shim kit.
Featuring a 90% increase in bending stiffness, these XD-A pushrods can be adjusted from 7.740" to 7.972" and allow for the use of lightweight rockers. .004" incremental adjustment is perfect for setting pre-load or lash.
See 896807-1 for a single pushrod or 896807-KIT for a complete kit with shims.
