COMP Cams rocker arm adjusting nuts are designed for the ultimate in strength and locking force. They are precision-ground for minimum runout and are tapered for extra strength in the locking area. The special alloys in the polylocks ensure a quality and strength not found in any other competitive products.

On the 302-351W Fords, simply remove the standard adjusting nut, slip the spacer over the stud, install the new nut and adjust the valves as necessary.
