Sealed Power E-986K Engine Piston Ring Set

Sealed Power E-986K Piston Ring Set

Sealed Power E-986K is a standard-size engine piston ring set built for 94.00 mm bores and 1.2 mm x 1.5 mm x 2.5 mm ring grooves. It uses a steel top ring with moly, a grey iron second ring with phosphate coating, and a low-tension 3-piece flex vent oil ring for precise sealing in modern GM V6 applications.

Compatible With Buick Enclave, Chevrolet Traverse, GMC Acadia, Cadillac CTS, and other listed vehicles, this Sealed Power E-986K ring set supports consistent compression control and oil management in engines that call for standard bore dimensions.

• 94.00 mm bore diameter and outside diameter
• Top ring material: steel with moly coating
• Second ring material: grey iron with phosphate coating
• Top ring face design: barrel face
• Second ring face design: reverse torsional
• Oil ring design: 3-piece flex vent
• Low oil ring tension for reduced drag
• Standard size, non-file-fit design
• Ring groove widths: 1.2 mm x 1.5 mm x 2.5 mm

Detailed Product Overview

Built for 6-cylinder engines, Sealed Power E-986K is engineered around the bore and groove dimensions used in a wide range of GM vehicles from 2004 through 2016. The moly-faced steel top ring helps maintain cylinder sealing under heat and load, while the reverse torsional second ring and phosphate-coated grey iron construction support stable oil control and ring seating. The low-tension oil ring design helps reduce friction while maintaining control of excess oil on the cylinder wall.

This part cross-references 2M5133 and 42072CP for the same application. Search terms such as 94 mm piston ring set, standard bore engine ring set, and GM 3.6L piston rings are commonly used by buyers looking for this application.

What This Part Helps Address

• Low compression caused by worn or damaged piston rings
• Excessive oil consumption from poor oil control
• Blow-by from weakened cylinder sealing
• Ring wear in standard-bore rebuilds
• Uneven sealing performance during engine overhaul

Installation Notes and Tips

Verify bore diameter, ring groove widths, and piston specifications before installation. This is a standard-size, non-file-fit ring set, so ring end gaps should still be checked during assembly. Clean cylinder walls thoroughly, confirm ring orientation, and follow the engine builder’s service procedures for break-in and lubrication.
