Hisun HS800 Piston Ring Set

Hisun Piston Ring Set

Part Number: 1311A-010000-0000

Application: Hisun 800cc ATV/UTV and many other 4x4 models

High-quality piston ring set, commonly used for Hisun 800cc engines and widely applicable to many other brands and displacements of 4x4 ATVs and UTVs

This product is a piston ring set commonly (but not exclusively) used for Hisun 800cc ATVs and UTVs, part number 1311A-010000-0000. Piston rings are critical sealing components of the engine, installed in the piston ring grooves, responsible for sealing the combustion chamber, controlling oil consumption, and conducting heat. This piston ring set includes complete compression rings and oil control rings, manufactured from high-quality alloy cast iron material, offering excellent wear resistance, elasticity, and high-temperature stability, effectively restoring engine compression pressure and power performance.

This piston ring set is not only suitable for Hisun 800cc models but also widely applicable to many other brands and displacements of 4x4 ATVs and UTVs, making it an ideal choice for engine overhaul and performance restoration.

This piston ring set is primarily used for the following models, but also applies to many other brands and displacements of 4x4 ATVs and UTVs:

• Quality Material: Made of alloy cast iron, offering excellent wear resistance, heat tolerance, and tensile strength for long service life.
• Precision Forming: End gap, side clearance, and back clearance are precisely controlled to ensure perfect fit against the cylinder wall after installation.
• Excellent Sealing: Compression rings provide effective sealing for strong cylinder pressure; oil control ring efficiently scrapes oil to reduce consumption and carbon buildup.
• Quick Break-in: Ring surfaces may feature special treatment for faster break-in, reducing the break-in period after engine overhaul.
• Wide Application: Not only suitable for Hisun 800cc engines but also fits many other brands and displacements of 4x4 ATVs and UTVs.

✅ Typical Symptoms of Worn or Damaged Piston Rings: Hard starting, significant power loss, burning oil (blue smoke from exhaust), excessive oil consumption, low compression, heavy spark plug fouling. If you experience these issues, the piston rings may need inspection or replacement.

⚠️ Installation Note: When installing piston rings, pay attention to the ring orientation and stagger the ring end gaps (typically 120 or 180 degrees apart) to prevent blow-by. Use a proper piston ring expander tool to avoid deforming or breaking the rings. New piston rings are best used with a new or honed cylinder for optimal sealing. Allow proper engine break-in after installation.
