High-quality C70 piston set for Moped, Cub and ATV, includes piston, gudgeon pin and circlips

This is a C70 Piston Set, suitable for various horizontal engine vehicles, including mopeds, Cub series motorcycles, and ATVs. The piston is one of the core components of the engine, responsible for withstanding combustion pressure and transmitting power through the connecting rod. Manufactured from high-quality aluminum alloy with precision machining and surface treatment, it offers excellent high-temperature strength, wear resistance, and thermal conductivity, ensuring proper engine compression and smooth power output.

• High-Quality Aluminum Alloy: Made from high-strength aluminum alloy, lightweight, good thermal conductivity, and high-temperature strength.
• Precision Machining: Piston skirt precision formed for proper cylinder wall fit, reducing friction and wear.
• Reinforced Ring Grooves: Ring grooves specially treated for wear resistance, extending piston ring life.
• Quality Gudgeon Pin: Made from alloy steel with surface hardening treatment, high strength and wear resistance.
• Complete Kit: Includes all components needed for installation, no need to purchase配件 separately.

🔧 Installation Tip: Before installing the piston, thoroughly clean the cylinder and piston. When installing circlips, ensure they are fully seated in the grooves with the opening away from the thrust direction. Use proper tools to install piston rings to avoid scratching the piston. Apply clean engine oil to the piston, rings, and cylinder wall before installation. It is recommended to replace piston rings and cylinder gasket simultaneously.
