Description
These Comp Cams 896809-16 XD-A Adjustable Pushrods are designed for drop-in fitment in GM LS engines, and are proven to 9,000-plus RPM in solid roller applications.
The patent-pending pushrods incorporate a top section that slides two inches inside a wider bottom section, with one or two shims captured in-between. The system provides a 90-percent increase in bending stiffness for enhanced valve train 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 (such as the COMP Cams SPR Radius Tip Rocker Arms) with XD-A Adjustable Pushrods allows higher RPM by creating a much more dynamically stable valve train system.
The pushrods are designed especially for engines with low-mass rocker arms and a light valve train. They allow adjustment over a range of .172″ in .004″ increments with shims. Sold in sets of 16 by thickness or as a 240-piece set containing all available thickness options. Top sections are available in 0/200″ increments for coarse adjustment and work with hydraulic as well as solid roller camshafts.
