• Chloroprene belt material with aramid fiber-loaded rubber construction
• Double-notched design for CVT operation
• Black finish with fabric bottom and notched profile
• OE Improved comparison rating for upgraded service performance
• Top width: 32 mm (1.246 in)
• Outside circumference: 1073 mm (42.256 in)
• Section designation: RVS-R

Product Details

The Gates G-Force Carbon Cord CVT Belt line was developed around carbon tensile cord technology to improve strength and reduce edge cord pullout. In this application, the belt uses specially formulated adhesion material around the cords to help maintain belt integrity under load and extend belt life. The result is a CVT belt suited to automatic continuously variable transmission systems that need consistent grip, stable tracking, and dependable power transfer.

This Gates 25C4108 belt is a practical choice for owners searching for a replacement CVT belt for power sport drivetrains, including vehicle-specific searches such as Polaris Ranger CVT belt, Polaris RZR CVT belt, and Honda Pioneer CVT belt applications where the listed dimensions and section match the original specification. This part cross-references Dayco XTX2279 for the same application.

What It Helps Address

• Slipping or inconsistent CVT belt engagement
• Excessive belt wear from heat and load
• Edge cord pullout in high-stress operation
• Loss of driveline response during acceleration
• Noise or vibration caused by a worn CVT belt

Installation Notes and Tips

Verify the belt dimensions, section designation, and CVT system requirements before installation. Confirm the 32 mm top width and 1073 mm outside circumference against the original belt specification, and inspect pulleys, sheaves, and clutch surfaces for wear before fitting the new belt. Proper alignment and correct belt break-in procedure help support consistent CVT performance.

For fitment-based searches, use the exact vehicle application listed for your model and compare the original belt number to Gates 25C4108 before ordering. This is especially important for Polaris Ranger, Polaris RZR, and Honda Pioneer CVT belt replacement searches where belt dimensions must match precisely.

Quality Assurance

Gates developed the G-Force Carbon Cord CVT Belt line with OE-style technology and upgraded carbon cord reinforcement for demanding transmission service. The belt construction is focused on strength, adhesion, and durability to support reliable CVT operation in high-performance applications.
