Detailed Description

This Sealed Power piston ring set is engineered for engines that require an 86.00 mm bore and standard ring dimensions. The barrel-face top ring, chrome steel construction, and low-tension 3-piece flex vent oil ring are selected to support cylinder sealing, oil control, and consistent compression in everyday street use. The E-1027KC is a strong match for drivers searching for a piston ring set for 2007-2017 Jeep Compass, 2007-2017 Jeep Patriot, or 2007-2012 Dodge Caliber with the listed groove widths and standard bore size. This part cross-references 2C4835 and 5191418AB for the same application.

What It Helps Address

• Low compression caused by worn ring sealing surfaces
• Excess oil consumption from tired oil control rings
• Blow-by related to ring wear or loss of cylinder sealing
• Smoke from oil entering the combustion chamber
• Uneven cylinder sealing in high-mileage engines

Installation Notes and Tips

Confirm bore size, ring groove widths, and piston compatibility before installation. Because this set is not file-fit, ring end gaps should be checked during assembly rather than altered by filing. Clean the ring lands thoroughly, verify cylinder wall condition, and follow the engine builder’s specifications for end gap, orientation, and lubrication. For fitment-based searches, this is a direct option for 2007-2017 Jeep Compass, 2007-2017 Jeep Patriot, and 2007-2012 Dodge Caliber applications that match the listed 86.00 mm standard configuration.

Quality Assurance

Sealed Power states that its parts are manufactured with advanced designs and materials under ISO- and QS-certified production systems to meet modern engine requirements. The E-1027KC reflects that manufacturing approach with application-specific ring materials and dimensions for consistent engine service.
