D.S.S. E Series Forged Piston and Ring Kits

D.S.S. Competition Engine offers E Series forged piston and ring kits for a variety of applications, including many Chevy and Ford V8 small block engines from 1963 and up—an ideal choice for a budget performance engine build.

Available with flat top or dish style pistons, in a wide range of size and stroke options, the kits are sold in sets of 8.
