The Namura NA-30015K Top End Kit is a complete standard-bore replacement assembly designed for select Suzuki LT-A750X KingQuad AXi IRS models. This kit includes the piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit needed to service the upper portion of the engine. It is engineered for reliable fitment and performance in compatible 750cc ATV applications.
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 11:1 compression design supports dependable combustion performance, while the 103.96 mm piston size is intended for standard-bore applications when matched with the correct cylinder specifications.
The piston skirts feature a MOS2 Teflon/molybdenum coating applied through a rolled-on process for a strong, durable bond. This coating helps reduce friction, improve heat transfer, and minimize the risk of cold seizures. Machined smooth piston heads help reflect combustion heat and reduce carbon buildup, while anodized domes improve heat resistance and durability compared with non-anodized designs.
