Designed for the most demanding, turbo-charged off-road CVT applications. With Gates proprietary materials and design, G-Force RedLine CVT belts handle extreme temperatures with excellent heat recovery, while maximizing load and torque capacity making it one of the most efficient CVT belts currently on the market.
Why G-Force RedLine CVT Belts?
- Greater heat resistance and recovery, even under severe duty cycles.
- Optimized, patented EE compound maximizes axial stiffness enabling belts to run at higher continuous torques or loads.
- Innovative design results in better acceleration, higher top speeds, less speed ratio and energy loss in extreme off-road environments.
- Improved durability, crack and wear-resistance means a longer-lasting, high-performance power transmission belt for the most demanding applications.
- Reduced environmental risk made without harmful chlorinated compounds.
Features
- First on the market to utilize Ethylene Elastomer compound to address the needs of larger SxS and high-horsepower ORVs in tough riding conditions.
- Next-generation EE compound offers maximum transverse stiffness and heat resistance, resulting in higher load capacity, higher peak torque capacity, less "heat fade" and less speed loss.
- Delivers 75% greater dynamic axial stiffness on average, up to 50% lower speed losses and better recovery from temperatures up to +170°C (+338°F) without power loss.
- Unmatched Temperature Capability - Runs cooler, resists glazing for better recovery and reduced cracking/chunking out after running at temps exceeding +149°C (+300°F).
- Extended Belt Life - Belt life increased 100-300% versus aftermarket competitive belts in severe duty lab test conditions and in field testing.
- Higher Power Capacity - Reduced speed (rpm) loss by 50% under high loads and increased load capacity by >10% compared to other aftermarket belt.

Vehicle Information
Polaris Pro RMK 850 Snowmobile (2019-2026)
The Polaris Pro RMK 850, a leading mountain snowmobile from 2019 to 2026, is renowned for its powerful 850 Patriot engine. This liquid-cooled, 2-cylinder, 2-stroke engine, with 840 cc displacement and Cleanfire Injection, was introduced in 2019, establishing a benchmark for performance with its exceptional power-to-weight ratio. Throughout its production, the Pro RMK 850 has seen key evolutions. In 2022, Polaris introduced the Matryx platform on certain models, bringing chassis and ergonomic enhancements, including the lightweight "Slash" design. For 2025 and 2026, the lineup expanded significantly with the addition of the Patriot 9R and Patriot Boost engine options, offering diverse performance characteristics. These later models also feature a redesigned throttle, a lower seat, improved running boards, and a lightweight headlight, with the 2026 models adding a 7S Ride Command screen. Trims are primarily distinguished by track length, such as 155, 163, 165, and 174 inches. FAQ:
Q: How do I ensure this part fits my specific Polaris Pro RMK 850?
A: Please use our year and model selector at the top of the page to confirm compatibility for your exact snowmobile. Q: Are there differences between the Pro RMK 850 models from 2019 to 2026?
A: Yes, there have been platform updates and new engine options introduced. Use our selector to find parts specific to your model year.
Maintenance
| Component | Interval | Details |
| Engine Oil and Filter | 25 h or 800 km or 1 month (break-in); then 50 h or 1,600 km or annually | Change oil and filter during break-in. After break-in, change filter with every oil change. Some guidelines also mention 100 h or 1,600 km. |
| Drive Belt | Regularly (inspection); as needed (replacement) | Inspect for wear before season and periodically. Check and adjust deflection. Break-in period recommended. |
| Spark Plugs | As needed (inspection/replacement) | Inspect and replace as needed. Ensure they are in good condition and tight pre-season. |
| Air Filter | As needed (inspection/replacement) | Inspect and clean often, especially in dusty conditions. Ensure proper installation of filter and airbox cover. |
| Coolant | Daily (level); seasonally (strength); yearly (pressure test); every two years (change) | Check level daily and add if needed. Inspect for leaks. Pressure test cooling system yearly. |
