If you are searching for Sealed Power E-897K piston rings for a Ford F-250 or Ford E-350 Econoline engine rebuild, verify bore size and groove width before ordering.

What This Part Helps Address

• Excessive oil consumption from worn oil control rings
• Low compression caused by worn or damaged piston rings
• Blow-by from poor cylinder sealing
• Oil fouling related to ring wear or loss of tension
• Engine rebuild needs on Ford F-250, F-350, and E-350 Econoline platforms

Installation Notes and Tips

Confirm bore diameter, ring groove widths, and piston specifications before installation. Measure cylinder wear and inspect ring lands, then check end gap and side clearance during assembly. This set is listed as standard size and is not file fit. For Ford F-250 HD, Ford F-350, and Ford E-350 Econoline engine service, follow the engine builder’s ring installation and break-in procedures.
