Gates G-Force RedLine CVT Belt for 2011-2014 Polaris RZR XP 900/1000

Unlock maximum performance from your ATV or UTV with the Gates G-Force RedLine 21R4140 drive belt, purpose-built for today’s most demanding off-road CVT applications. Whether you are running hard in the dunes, rock gardens, desert washes, or on race courses, this belt is engineered to keep delivering consistent power when standard belts start to fade.

The G-Force RedLine series uses a proprietary Ethylene Elastomer (EE) compound that dramatically improves heat resistance and recovery compared to conventional CVT belts. This next-generation compound provides maximum transverse and axial stiffness, allowing the belt to carry higher continuous loads and peak torque without excessive deformation or slip. The result is less heat fade, reduced speed loss, and more efficient power transfer under extreme conditions.

In real-world riding, that advanced construction translates into quicker acceleration and higher potential top speeds, with less energy lost through belt flex and friction. Riders benefit from a more responsive throttle feel and more consistent clutching as temperatures climb. Even during severe duty cycles, the belt’s enhanced heat recovery helps maintain performance, so you can stay on the throttle longer with greater confidence.

Durability is another core advantage of the G-Force RedLine 21R4140. The belt is designed for improved crack, wear and chunking resistance, extending service life in harsh environments. Lab and field testing show significantly longer life versus many aftermarket alternatives when subjected to high loads, elevated temperatures, and aggressive riding styles. For riders who regularly haul, climb, or run big power, this added durability can mean fewer belt changes and more uninterrupted ride time.

The G-Force RedLine construction also helps reduce environmental impact by eliminating harmful chlorinated compounds from the belt materials, while still delivering the high power capacity modern machines require. Every belt in this line is extensively lab and field tested to validate performance in real off-road conditions before it reaches your machine.

If you are upgrading clutches, adding power, or simply tired of inconsistent belt performance, the Gates G-Force RedLine 21R4140 is a strong choice for demanding riders. Combine it with proper clutch setup and cooling for a robust, efficient CVT system that is ready for hard trail use, racing, and heavy work alike.

Note: This drive belt is vehicle specific. Always verify part number 21R4140 against your ATV/UTV fitment before installation.
