Common Repair Uses

• Restores compression loss caused by worn piston rings
• Addresses oil consumption related to ring wear
• Helps reduce blow-by in high-mileage engines
• Supports engine rebuilds requiring standard-size rings
• Replaces damaged or fatigued rings found during teardown

Installation Notes and Tips

Confirm cylinder bore condition and ring end gap before assembly. Because this is not a file-fit ring set, do not modify the rings unless the service procedure for the engine specifically calls for it. Match the application to the correct year, make, and model before installation, and verify that the engine is a 6-cylinder standard-size setup. For best results, follow the factory service manual for ring orientation, gap placement, and break-in procedure.

Quality Assurance

Sealed Power uses modern materials and ISO- and QS-certified manufacturing processes to produce engine components that meet the demands of current engine service. E-953KC is built to the listed specifications for the confirmed vehicle applications.
