Sealed Power Engine Piston Ring Set P/N:E-991K
Sealed Power E-996K piston ring set for the 2006-2016 Chevrolet Express 2500 V8 6.6L and other vehicles seals each cylinder against combustion pressure and controls oil on the cylinder wall. The set covers eight cylinders, and each Sealed Power piston ring meets or exceeds OEM specifications.
Rising oil use, blue smoke from the tailpipe or weak compression can mean the rings are worn. These signs alone do not prove the rings are at fault, since leaking valve stem seals can burn oil too.
The 2006-2016 Chevrolet Express 2500 V8 6.6L, the 2006-2016 Chevrolet Express 3500 V8 6.6L, the 2010-2016 Chevrolet Express 4500 V8 6.6L and many other vehicles take one set each. Open the "Vehicles it fits" section to check your exact model and engine.
