Detailed Description

The Sealed Power E-937K piston ring set is engineered for engines that use 96.00 mm cylinder bores and standard groove dimensions. Its steel moly top ring and reverse torsional second ring are selected to support consistent cylinder sealing, while the 3-piece flex vent oil ring helps manage oil control in everyday driving and rebuild applications. This part number, E-937K, is commonly searched for Chevrolet Express, Silverado, Tahoe, GMC Sierra, and Yukon engine rebuilds where standard-size ring dimensions are required.

Sealed Power focuses on modern materials and controlled manufacturing processes to deliver parts that meet demanding engine requirements. This ring set cross-references MAHLE 41859CP for the same application.

What It Helps Address

• Low compression caused by worn piston rings
• Excessive oil consumption from poor ring sealing
• Blow-by and crankcase pressure buildup
• Loss of cylinder sealing during engine rebuilds
• Uneven ring wear in high-mileage GM V8 engines

Installation Notes and Tips

Verify bore size, groove width, and ring end gap before assembly. This is a standard-size ring set and is not file fit, so confirm cylinder condition and piston groove measurements during engine preparation. Clean ring lands thoroughly and follow the engine builder’s specifications for ring orientation and end-gap checks. Compatible With 2000-2014 Chevrolet Tahoe, 2000-2014 GMC Yukon, and other listed GM truck and SUV applications using 96.00 mm bores.
