Domestic Piston Rings
We have a complete line of (In Stock) Ford, Chevy & Dodge/Mopar rings for all our stocking pistons. Our regular stocking sets include a special high density moly surface top ring that seats quickly and holds its seal. The second ring is a reverse-twist taper face cast iron design and the oil ring is a standard tension three piece type. All sets are .005 over-size for file fit end gap unless otherwise noted.
