I for one would like to know where to buy Dykes rings. I bought a set of OEM std bore Muscle Parts pistons from John V. last yr and haven`t found any rings. I can send the pistons out and have the top ring modified but is it worth the cost? Any one know who would still be producing them?
Dykes ring are made in two versions and it is related to the amount of "step" or undercut on the ring. If the ring is .0625 , a "017" would measure about .0455 on the undercut portion and an "031" would be about .0315 on the undercut portion. To measure the piston , you have to check with a pin gauge (most accurate) or feeler gauges to determine which "step" you need. Akerly and Childs is another ring company that can supply the dyke style rings , possibly less expensive than T/S. Pistons cut for dykes rings CAN be recut for a 1/16th ring and it will leave a small undercut above the ring. This is OK and "modern" piston companies are doing this calling it a "gas distribution groove" and it does improve ring seal and power output. Randy
