G-Force CVT Belt Product Line Details

The G-Force CVT Belt line by Gates focuses on delivering durable and high-performance belts specifically designed for powersport applications. The 39G4455 model incorporates double-notched construction and aramid cords to provide strength and flexibility, ensuring consistent power delivery and extended belt life under demanding conditions.

Technical Description and Features

This automatic continuously variable transmission belt is constructed with a chloroprene rubber compound that offers resistance to heat and wear. The double-notched design enhances flexibility, allowing the belt to conform to the pulleys more effectively, which is critical for smooth operation in powersport vehicles. The aramid cord material provides high tensile strength, reducing stretch and maintaining belt integrity over time. The fabric bottom improves grip and reduces slippage, while the 24-degree angle design optimizes the belt’s engagement with the transmission system. With an outside circumference of 1162 mm and a top width of 36 mm, this belt is engineered to meet OE performance ratings, making it a reliable replacement for compatible models.

Applications and Problem Solving

• Replacement for worn or damaged CVT belts in powersport vehicles
• Addresses slipping or loss of power transmission in automatic CVT systems
• Helps reduce belt noise caused by improper fit or wear
• Improves transmission efficiency by maintaining proper belt tension
• Prevents premature belt failure due to heat and wear resistance

Installation Notes and Tips

When installing the Gates G-Force CVT Belt 39G4455, ensure the belt is properly aligned with the pulleys and tensioned according to the vehicle manufacturer’s specifications. The double-notched design requires careful handling to avoid damage during installation. Inspect the transmission components for wear or damage before fitting the new belt to ensure optimal performance and longevity.
