Sealed Power Engine Piston Ring Set P/N:E-925K 20
Sealed Power E-925K piston ring set for the 1997-2006 Jeep Wrangler 6-cylinder 4.0L and other vehicles seals the combustion chamber and controls oil on the cylinder wall. Every Sealed Power piston ring in this engine piston ring set meets or exceeds OEM specifications.
Blue exhaust smoke, rising oil use or low compression can mean worn rings, though worn valve stem seals or a clogged PCV valve can be behind them too, so find the cause before a rebuild. The engine takes one set, with one ring pack for each of its six cylinders.
As a piston ring set, it also goes into the 1996-2004 Jeep Grand Cherokee 6-cylinder 4.0L and the 1996-2001 Jeep Cherokee 6-cylinder 4.0L.
