Product Details

Gates positions the G-Force RedLine line as a new generation of CVT belts for demanding use, with a focus on stronger acceleration response, higher top-speed potential, and reduced energy loss in extreme off-road conditions. The 31R4573 uses a double-notched profile and fabric bottom construction to support consistent belt behavior under load. For shoppers comparing CVT belt replacements for powersport and specialty drivetrains, this Gates 31R4573 belt is a direct part-number reference to keep on hand during service.

This part cross-references Dayco HPX2249 for the same application.

Common Issues This Belt Can Address

• Slipping or inconsistent CVT engagement
• Loss of acceleration response under load
• Reduced top-speed performance from belt wear
• Heat-related belt degradation in off-road use
• Drive ratio inconsistency during hard acceleration

Installation Notes

Verify belt dimensions, section designation, and CVT system requirements before installation. Match the 31R4573 to the correct application by outside circumference, pitch length, top width, and angle. Inspect pulleys, clutch surfaces, and belt alignment during service so the new belt seats correctly and wears evenly. For vehicle-specific searches, use terms such as Gates 31R4573 CVT belt, G-Force RedLine belt replacement, and powersport CVT belt for off-road applications.
