Sealed Power E-1003K piston ring set for the 2011-2021 Ford F-250 Super Duty V8 6.7L and other vehicles seals each piston to its cylinder wall and controls oil. Each piston gets a Sealed Power piston ring stack made up of a top ring, a second ring and an oil ring.
- Moly-plasma top ring with a porous surface that carries oil, forms a more effective compression seal and reduces friction and drag
- Carbidic cast iron second ring that seats instantly and controls inter-ring pressure to improve cylinder sealing
- Second ring passes heat efficiently from piston to cylinder and aids oil control
- Conformatic oil ring that keeps tension uniform while assuring a positive seal
