Reproduction of the forged Cooper/Cooper S rocker; stronger than standard A+ rocker and delivers more lift. Has replaceable bronze bushing and original oil drillings to adjuster screw. Includes adjuster screw and lock nut. A nice retrofit for a modern A+ engine to superior spec of original A-series. Sold each, use in sets of eight (8).
These will have to be finish-honed to size before installation.
