The NAMURA NA-30053K Top End Kit is designed for select Suzuki KingQuad 500 all-terrain vehicles with a standard 87.45 mm bore and 10.0:1 compression ratio. This SCEM composite cylinder kit provides the essential components needed for a reliable top-end rebuild, including a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit. The kit is engineered for proper fitment and dependable performance in compatible Suzuki applications.
The piston features NAMURA’s MOS2 Teflon and molybdenum-coated skirts. This rolled-on coating process creates a bond claimed to be significantly stronger than spray-on alternatives while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. A machined smooth head helps reflect combustion heat and reduce carbon buildup, supporting piston protection and consistent engine operation.
An anodized dome improves heat resistance and durability, while the hypereutectic casting process increases silicon content to help control thermal expansion and improve wear resistance. These design features allow the piston to withstand higher cylinder temperatures and support long-term service in demanding ATV conditions. The NAMURA NA-30053K is compatible with 2011–2016 Suzuki LT-A500X KingQuad AXi IRS models and select 2009 and 2011–2013 Suzuki LT-A500XP KingQuad AXi EPS IRS models. Verify the vehicle year, model, bore specification, and compression ratio before installation.
