Sealed Power Engine Piston Ring Set P/N:E-991K
Sealed Power E-651K piston ring set for the 1994-1996 Ford F-250 V8 7.3L and other vehicles seals the cylinder to hold compression and control oil. Each Sealed Power piston ring is made to exacting tolerances and meets or exceeds OEM specifications.
When an engine piston ring set wears, the engine can use more oil, blow blue-gray smoke from the exhaust or lose power. Before you replace the rings, rule out other sources of oil use and smoke, such as valve stem seals or an external oil leak, and have a shop test compression.
Vehicles it fits include the 1994-1996 Ford F-250 V8 7.3L, the 2003 Ford E-350 Club Wagon V8 7.3L and the 1999-2003 Ford E-350 Super Duty V8 7.3L.
