PISTON KIT LTZ400 KFX400 90.00, NAMURA NA-30002-B SUZ, KAW

Namura Piston Kit B for LTZ400 KFX400 with a 90.00mm bore. Part number NA-30002-B. This high-performance piston assembly is engineered in the USA and manufactured in Taiwan. It is constructed from high-silicon content Hypereutectic cast aluminum material, which offers less heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing. The piston features a machined, smooth crown for reduced carbon buildup, increased horsepower, and improved fuel economy. Hard anodized crowns are 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures when combined with Teflon/Molybdenum coated skirts. MOS2 (Teflon/Molybdenum) coated skirts perform at the highest standards, reducing friction and heat for added power and longevity. Namura rings match the OEM design, with this being a fractional oversize B (.0004 in.).
