Sealed Power Engine Piston Ring Set P/N:E-248K
Sealed E-248K 40 piston ring set for the 1960-1963 Ford F-250 V8 5.4L and other vehicles seals each piston against its cylinder wall during an engine rebuild. The rings meet or exceed OEM specifications and cover applications over 35 years old.
Heavy oil use, blue exhaust smoke or a drop in compression can mean worn piston rings, and this engine piston ring set is made for that rebuild. Worn valve seals or a leaking head gasket can be behind some of these signs too, so find the cause before you buy.
This piston ring set is also a direct-fit replacement for the 1960-1963 Ford F-100 V8 5.4L and the 1960-1963 Ford F-350 V8 5.4L, among many other Ford, Edsel, Lincoln, Mercury and Oldsmobile models.
