The NAMURA NA-30001K Top End Kit is a complete standard-size 68.47 mm replacement kit designed for select Suzuki KingQuad 300 and LT-F300F KingQuad 4X4 [IRS] models. With an 11:1 compression ratio, this kit provides the essential components needed to refresh the upper end of the engine, including a piston, piston rings, wrist pin, circlips, top-end bearing, and gasket kit. It is manufactured for dependable fitment and service in compatible Suzuki applications.
The piston uses a hypereutectic casting process that increases silicon content for controlled expansion, improved wear resistance, and the ability to withstand higher cylinder temperatures. The MOS2, or Teflon/Molybdenum, coated skirts use a rolled-on application process designed to create a stronger bond than conventional spray-on coatings. This coating helps improve heat transfer, reduce friction, and minimize the risk of cold seizures during operation.
Additional piston features include machined smooth heads that help reflect combustion heat and reduce carbon buildup, along with anodized domes that enhance heat resistance and durability. The kit fits 1999–2002 Suzuki LT-F300F KingQuad 4X4 [IRS] models and 1991–1996 Suzuki LT-F4WDX KingQuad 300 [IRS] models. Verify the vehicle model and year before installation to ensure compatibility.
