Detailed Description

The Sealed Power E-999K piston ring set is designed for engines that require a 94.00 mm bore and standard groove dimensions. The steel moly top ring and grey iron second ring are selected for consistent sealing and cylinder wall contact, while the 3-piece flex vent oil ring supports oil control in demanding street and truck use. This part number, E-999K, is listed for 1998-2005 Lexus LX470, 1998-2005 Toyota Land Cruiser, 2003-2004 Lexus GX470, 2003-2004 Toyota 4Runner, 2001-2004 Toyota Sequoia, and 2000-2004 Toyota Tundra.

Sealed Power uses modern materials and ISO- and QS-certified manufacturing practices to produce engine components that meet the demands of current engine rebuild standards. This part cross-references 130110F010 and RST043 for the same application.

What It Helps Address

• Low compression from worn or damaged piston rings
• Excessive oil consumption caused by poor ring sealing
• Blow-by from cylinder sealing loss
• Smoke from oil control issues in the cylinder bore
• Engine rebuild needs on 94.00 mm bore Toyota and Lexus V8 engines

Installation Notes and Tips

Verify bore diameter, ring groove widths, and standard-size requirements before assembly. Check ring end gap, cylinder wall condition, and piston groove cleanliness during engine rebuild work. Confirm application details for your specific Lexus LX470, Toyota Land Cruiser, GX470, 4Runner, Sequoia, or Tundra engine before installation.

Quality Assurance

Sealed Power manufactures engine parts using controlled processes and certified production standards to support consistent fit and performance. The E-999K is built as a precision replacement piston ring set for rebuilds that require accurate bore and groove specifications.
