Top ring land is .300 thick to withstand the following. The rings are also a modern design. Low tension to provide better sealing and less HP wasting friction in the bore.
Applications include:
-Naturally aspirated
-Turbocharged
-Nitrous
The compression height of the piston is made so that only .015 is needed to be milled from the deck of engine to "Zero Deck" the engine. Stock pistons require .030-.035 to zero deck which also weakens the deck.
