Restore top-end performance with the NAMURA NA-30001-2K Top End Kit, designed for select Suzuki KingQuad 300 ATV applications. This 68.97 mm, +0.50 mm oversize kit features an 11:1 compression ratio and includes the piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit needed for a complete upper-engine rebuild.
The piston uses a hypereutectic casting process that increases silicon content to help reduce expansion, improve wear resistance, and withstand higher cylinder temperatures. Its MOS2, or Teflon/molybdenum, coated skirts are applied using a rolled-on process for a strong bond that helps reduce friction, improve heat transfer, and minimize the risk of cold seizures. Machined smooth heads help reflect combustion heat and reduce carbon buildup, while anodized domes improve heat resistance and durability.
Manufacturer part number NA-30001-2K is engineered for fitment on 1999–2002 Suzuki LT-F300F KingQuad 4X4 with independent rear suspension and 1991–1996 Suzuki LT-F4WDX KingQuad 300 with independent rear suspension. Verify the engine, model year, bore specification, and required oversize before installation. Professional installation and proper cylinder preparation are recommended for reliable performance and long service life.
