FULL DESCRIPTION
Wiseco Piston Kit for Honda TRX420 Rancher
Experience the superior strength and durability of a forged piston with this Wiseco Piston Kit. Engineered for extreme racing conditions, forged pistons are significantly tougher than cast pistons, providing enhanced resistance to abuse and catastrophic failure. The condensed grain structure, aligned with the part's features, results in higher mechanical properties and improved impact and fatigue resistance.
This piston kit is designed to optimize the strength-to-weight ratio for maximum performance. It features:
- ArmorGlide Skirt Coating: This advanced coating minimizes friction, maximizes horsepower, and improves wear resistance by providing exceptional lubrication and bond technology. It also allows for a tighter piston-to-bore fit.
- OEM Style Tin Coating: Assists in the break-in process for your machine.
- Low-Expansion, Low-Friction Alloy: Utilizes the same high-quality alloy used by major Japanese engine manufacturers.
- Precision Manufacturing: Crafted using state-of-the-art CNC equipment.
This Wiseco piston kit is built to withstand the demands of high-performance motorsport applications, ensuring reliability and power when you need it most.
