Detailed Description

Sealed Power E-1023K piston rings are specified for standard 96.00 mm bores and are built around a steel w/moly top ring, cast iron second ring, and 3-piece flex vent oil ring design. The barrel-face top ring and reverse torsional second ring help support cylinder sealing and oil control in rebuild and repair work. This part cross-references MAHLE 42216CP for the same application. Fits 2020-2023 Chevrolet Silverado 1500, 2015-2020 Chevrolet Cheyenne, and 2014-2019 GMC Sierra 1500 applications where the engine uses 1.2 mm, 1.5 mm, and 2.5 mm ring groove widths.

What It Helps Address

• Excessive oil consumption from worn piston rings
• Low compression caused by ring wear or loss of sealing
• Blow-by from poor cylinder sealing
• Smoke from oil control ring wear
• Rebuild needs on standard-bore 96.00 mm V8 engines

Installation Notes and Tips

Verify bore diameter, ring groove widths, and engine configuration before installation. Confirm the cylinder bore is 96.00 mm and that the piston grooves match 1.2 mm, 1.5 mm, and 2.5 mm ring widths. Check ring end gap and follow the engine builder’s measurement procedure during assembly. Fits 2020-2023 Chevrolet Tahoe, 2020-2023 GMC Yukon, and 2020-2023 GMC Yukon XL, along with 2022 Chevrolet Silverado 1500 LTD and 2022 GMC Sierra 1500 Limited applications listed for this ring set.
