Sealed Power Engine Piston Ring Set P/N:E-942K 30
Sealed Power E-942K piston ring set for the 2007 Chevrolet Silverado 2500 HD Classic V8 8.1L and other vehicles seals each piston against its cylinder wall. This engine piston ring set puts a Sealed Power piston ring in the top, second and oil positions of all eight cylinders and meets or exceeds OEM specifications.
Blue exhaust smoke, rising oil use or weak compression can mean the rings are worn, though worn valve seals can also let an engine burn oil and a leaking head gasket can also lose compression, so find the cause before you replace the rings.
The 2007 Chevrolet Silverado 2500 HD Classic V8 8.1L, the 2007 Chevrolet Silverado 3500 Classic V8 8.1L and the 2007 GMC Sierra 2500 HD Classic V8 8.1L each take one set, and so do more vehicles. If your vehicle is not named here, look up its model and engine in the Vehicles it fits section on this page.
