The NAMURA NA-30002K Top End Kit is designed for standard-bore applications using an 89.96 mm piston in select Arctic Cat, Kawasaki and Suzuki models. This complete kit includes the piston, piston rings, wrist pin, retaining clips, top-end bearing and gasket kit, providing the primary components needed for a reliable top-end rebuild. It is intended for cylinders with a Nikasil coating and is built to support proper fitment and dependable engine performance.
The piston uses NAMURA’s hypereutectic casting process, which increases silicon content to help reduce expansion and improve wear resistance under elevated cylinder temperatures. The skirt features a rolled-on MOS2 coating made with Teflon and molybdenum. This bonded coating helps reduce friction, improve heat transfer and minimize the risk of cold seizures during operation. A machined-smooth head helps reflect combustion heat and reduce carbon buildup, while the anodized dome improves heat resistance and durability.
This top-end kit fits 2003–2006 Kawasaki KFX 400 models, the 2003 Kawasaki KLX400R, 2004–2008 Arctic Cat 400 DVX models, and 2004–2006 Arctic Cat 400 DVX applications. Verify the vehicle year, model, cylinder condition and standard-bore specification before installation. The NAMURA manufacturer part number and vendor part number are NA-30002K, making it easier to match this kit with the correct application and replacement components.
