NA-50090-BK Top End Kit Twin Cylinder 92.96/+0.01 10.6:1 Pol
Elevate your engine's performance with the NA-50090-BK Top End Kit, designed specifically for twin-cylinder applications. This high-quality kit provides everything you need to enhance your engine's efficiency and power.
Key Features:
- Comprehensive Kit: Includes piston, rings, wrist pin, clips, top end bearing, and a complete gasket kit.
- MOS2 Coating: The Teflon/Molybdenum coated skirts are applied using a rolled-on process that forms a bond 10 times stronger than conventional spray coatings. This technology leads to increased heat transfer, reduced friction, and helps mitigate cold seizures.
- Machined Smooth Heads: These heads efficiently reflect combustion heat and minimize carbon buildup, providing protection to the piston top. Tests indicate potential horsepower and fuel economy improvements of up to 6%.
- Anodized Domes: The anodization increases heat resistance and durability, resulting in pistons that are 75% stronger than their non-anodized counterparts.
- Hypereutectic Casting Process: This innovative process enhances the silicon content, thus reducing expansion rates and delivering exceptional wear resistance. It also allows the pistons to endure higher cylinder temperatures.
Upgrade your engine with the NA-50090-BK Top End Kit and experience a new level of performance, efficiency, and reliability.
