Sealed Power Engine Piston Ring Set P/N:E-424K
Sealed E-424K 20 piston ring set for the 1967-1974 Dodge Charger V8 7.2L and other vehicles seals each piston against its cylinder wall. It is an oversized set for rebuilding older V8 engines.
Blue exhaust smoke from burning oil, low compression or a loss of power can mean worn rings. These signs alone do not prove the rings are at fault, since worn valve seals can also let oil into the combustion chamber. The set has rings for each cylinder, and one set is all the application takes.
The 1966-1977 Chrysler Town & Country V8 7.2L and the 1966-1971 Chrysler 300 V8 7.2L are among the many Chrysler, Dodge and Plymouth models it fits. If your car is not named here, look up your own year and model in the "Vehicles it fits" section. The set meets or exceeds OEM specifications.
