Application Details

This Sealed Power piston ring set is listed for Jeep TJ, Wrangler, Grand Cherokee, and Cherokee applications with the specified piston and groove dimensions. It is a fitment-based choice for 1996-2006 Jeep 4.0L engine rebuild work where standard bore sealing components are required. If you are sourcing an engine piston ring set for a Jeep Cherokee, Jeep Grand Cherokee, or Jeep Wrangler rebuild, E-925K matches the listed bore and groove specifications.

This part cross-references 2M4815 and 41870CP for the same application.

What It Helps Address

• Low compression from worn or damaged piston rings
• Excessive oil consumption caused by ring wear
• Blow-by from poor cylinder sealing
• Reduced ring control in standard bore rebuilds
• Uneven sealing performance in high-mileage Jeep engines

Installation Notes and Tips

Verify bore diameter, ring groove widths, and piston compatibility before assembly. This set is specified for use with the H802CP piston and standard 1.5 mm / 1.5 mm / 4.0 mm groove widths. Confirm cylinder condition, ring end gap, and ring orientation during engine assembly for proper sealing and break-in.

Quality Assurance

Sealed Power parts are manufactured using modern materials and ISO- and QS-certified production processes to meet the demands of current engine applications. The E-925K reflects that engineering approach with application-specific ring design and standard-size dimensions for listed Jeep engine rebuilds.
