Sealed Power E-1002KC Piston Ring Set

Sealed Power E-1002KC is an engine piston ring set built for 94.00 mm bore applications with standard sizing and a 1.2 x 1.2 x 2.0 mm groove width layout. It uses a steel top ring with chrome, a grey iron second ring, and a low-tension 3-piece flex vent oil ring for controlled sealing and oil management in modern V8 engines.

The Sealed Power E-1002KC part number is also referenced by 2C4586, 130110S011, and RSTO50 for the same application.

What It Helps Address

• Compression loss from worn or damaged piston rings
• Excess oil consumption caused by tired oil control rings
• Blow-by that can affect crankcase sealing and engine performance
• Uneven sealing in high-mileage or rebuilt Toyota and Lexus V8 engines
• Ring fitment issues when standard-size 94.00 mm components are required

Installation Notes

Verify bore diameter, groove widths, and ring end gap before assembly. This is a standard-size ring set and is not file fit, so confirm the cylinder finish and piston groove condition during engine work. Follow the engine builder’s measurement and break-in procedures for the specific Toyota or Lexus application.

Quality Assurance

Sealed Power states that its parts use advanced designs, modern materials, and ISO- and QS-certified manufacturing processes to meet the demands of current engines. The E-1002KC is built to those standards for consistent fit and function in the listed applications.
