Sealed Power Engine Piston Ring Set P/N:E-261K
Sealed Power E-261K 30 piston ring set for the 1967-1970 Ford Mustang V8 7.0L and other vehicles seals each piston against its cylinder wall. It is an engine piston ring set in a 0.030 inch oversize, made for rebuilding older engines. These Sealed Power piston rings cover eight cylinders.
Worn piston rings can show up as oil use, blue exhaust smoke or lower compression. Before you replace them, rule out other sources of oil use or lost compression, such as valve seals or a leaking head gasket; a shop can run a compression or leak-down test. This listing is one set, with rings for each of the eight cylinders.
This piston ring set fits the 1967-1970 Ford Mustang V8 7.0L, the 1969-1970 Mercury Marauder V8 7.0L and the 1966-1970 Ford Country Sedan V8 7.0L, and it meets or exceeds OEM specifications. If your car is not named here, look it up in the "Vehicles it fits" section, where the other Ford and Mercury models are covered.
