Valve Adjusting Wrench Full Bore

Most common adjuster nut sizes are 7/16", 1/2" or 9/16" and adjuster hex are 1/8", 3/16" or 5/32". Makes life easy in the pits, crack the adjuster nut loose, tighten or loosen the adjuster to get the clearance you want between the valve tip and rocker arm and snug the adjuster nut down and move on to the next cylinder that quickly.

Please pick adjuster nut size as well as adjuster hex size from the drop down menu.
