SOHC Hairpin Valve Spring Top Cup and Collet - Inlet

CNC Machined top cup, to take tapered collets, to fit all SOHC engines. Note: These top cups are sold complete with a matching set of collets (pair) to fit a 11/32" inlet valve. Although these are made using the original taper, I have found many pattern collets have slight variations and do not seat properly. Therefore these top cups have been machined with exactly the same taper as the collets and are sold as a matching pair.
