Yeah! You can run anything that'll fit in a stock width & depth ring groove for your particular engine.

reading the 2009 nhra rulebook for stock, under pistons, there is nothing saying this is an illegal part. as long as there is no mods to piston to run ring, its legal. and to think, somebody has thought to finally build a ring just like this. i do know of a few people, whos names will remain nameless, that already use these rings that they have customize. there are gains to be had, depending on how cylinders are prepared. rick.

This is yet another example where it costs the racer more money to stay within the rules than to allow a piston with any ring width. The piston makers don't charge any more or less for a thin or fat ring groove. But you'll sure pay for these spacers.
No different than my argument to allow "true" solid lifters in Stock. You can buy a "true" solid lifter set for $85.00 or so, or you can spend $300-$800 on a "quasi hydraulic" lifter that only has .015" of plunger travel. In the end, the engine doesn't know the difference from one to the other. But your wallet does.

This has been being done by some people since the late 70's. Just goes to the power of advertising.
