Detailed Description

Built for engine rebuild and overhaul work, the Sealed Power E-920X piston ring set is specified for standard bore engines with 1.5 x 1.5 x 3.0 mm ring groove widths. The reverse torsional design helps the rings seat and maintain cylinder sealing under operating load, while the grey iron ring materials provide the durability expected in everyday street and work-truck use. This part cross-references MAHLE 51786CP for the same application. Fits 1996-2009 Chevrolet Silverado 1500, 1996-2008 Chevrolet Express 1500, and 1999-2007 GMC Sierra 1500 applications listed in the fitment data.

What This Part Helps Address

• Low compression caused by worn or tired piston rings
• Excessive oil consumption from ring wear or poor sealing
• Blow-by that can affect crankcase pressure and engine performance
• Smoke from worn oil control rings
• Loss of cylinder sealing during engine rebuilds

Installation Notes and Tips

Verify bore diameter, ring groove widths, and piston specifications before installation. Because this is a file-fit ring set, confirm end gap during assembly and follow the engine builder’s measurements for the specific block and piston combination. Clean ring lands thoroughly and inspect cylinders for taper or scoring before final assembly. Fits 1996-2005 Chevrolet Astro, 1996-2005 Chevrolet Blazer, and 1996-2004 Chevrolet S10 applications listed in the fitment data.

Quality Assurance

Sealed Power states that its parts are manufactured with advanced materials and produced in ISO- and QS-certified facilities to meet the demands of modern engines. The E-920X reflects that manufacturing approach with a standard-size, application-specific piston ring design for rebuild accuracy.
