Premium Phosphated Cast Iron Liners Superior Lubrication: Manganese phosphating creates a micro-porous surface that excels in oil retention, ensuring perfect lubrication during critical break-in. Anti-Scuffing Protection: The phosphated layer acts as a solid lubricant barrier, significantly reducing the risk of scuffing or seizure under high-load conditions. High Wear Resistance: Cast from high-grade alloy iron with a pearlitic structure, providing exceptional thermal stability and long-term bore durability. Rust & Corrosion Defense: Full-surface chemical treatment protects against rust during storage and resists erosion from combustion by-products. Precision Honing: Cross-hatch finish ensures rapid ring seating, lower oil consumption, and maximum engine power output.
