Key Features

Direct replacement for Polaris OEM CVT belt 3211202 on 2017-2019 RZR XP Turbo models
Patented fiber-reinforced Ethylene Elastomer compound recovers from clutch temperatures up to 338F (170C) without power loss
High-tensile aramid cords resist stretch for consistent clutch engagement and shift quality
75% greater dynamic axial stiffness on average and up to 50% lower speed (RPM) loss under high load, per Gates testing
Lasted 100-300% longer than competitive aftermarket belts in Gates severe-duty lab and field testing
Gates catalog dimensions: 44.066 in (1,119 mm) outside circumference, 1.499 in (38 mm) top width, 25-degree belt angle
Flagship G-Force RedLine series, purpose-built for turbocharged, high-horsepower UTVs
Cross-references: Dayco XTX2288; carbon-cord sibling Gates G-Force C12 50C4289

The Gates 50R4289 is a G-Force RedLine CVT drive belt that fits the 2017-2024 Polaris turbocharged RZR models as a direct replacement for Polaris OEM belt 3211202. It is the flagship belt in Gates' G-Force family, built from a patented fiber-reinforced Ethylene Elastomer (EE) compound with high-tensile aramid cords for turbocharged, high-horsepower UTVs.

Gates rates the RedLine construction at 75% greater dynamic axial stiffness on average and up to 50% lower speed (RPM) loss under high load than conventional CVT belt construction, with recovery from clutch temperatures up to 338°F (170°C) without power loss. In Gates severe-duty lab and field testing, RedLine belts lasted 100-300% longer than competitive aftermarket belts. That added stiffness and heat capacity is what keeps clutch engagement consistent on long sand pulls, hill climbs, and hard-throttle desert runs.

Fitment

This belt fits the 2017-2021 Polaris RZR XP Turbo and XP 4 Turbo, the 2018-2021 RZR Turbo S and Turbo S 4 (including Velocity variants), the 2020-2024 RZR Pro XP and Pro XP 4, and the 2022-2024 RZR Turbo R and Turbo R 4. It installs as a direct replacement for the factory 3211202 belt with no modifications. Does not fit naturally aspirated Polaris RZR models such as the RZR XP 1000 or RZR 900 — the 3211202 belt application is specific to Polaris turbocharged RZR platforms. Always match your OEM belt number (3211202) before ordering.

Break-In

Gates recommends breaking in a new RedLine belt with three heat cycles: drive for 20 minutes at 25-45 mph (40-72 km/h) while avoiding hard acceleration and hills, then shut the engine off and let the belt cool for 30 minutes, and repeat the cycle twice more. A belt broken in gently runs smoother and delivers maximum life and performance.

FAQ

Does the Gates 50R4289 fit the Polaris RZR XP Turbo?

Yes. The Gates 50R4289 fits the 2017-2024 Polaris turbocharged RZR models, including EPS, Dynamix, Fox Edition, and LE trims, and replaces Polaris OEM belt 3211202.

What is the difference between the Gates RedLine 50R4289 and the Gates C12 50C4289?

Both replace Polaris OEM belt 3211202 on the same vehicles. The RedLine 50R4289 uses high-tensile aramid cords in Gates' Ethylene Elastomer compound for maximum heat resistance and load capacity, while the G-Force C12 50C4289 uses a carbon tensile cord for minimal stretch. The RedLine is Gates' top-tier belt for turbocharged UTVs.

Does a Gates RedLine CVT belt need a break-in period?

Yes. Gates recommends three 20-minute drive cycles at 25-45 mph with 30-minute engine-off cool-downs between them, avoiding hard acceleration until break-in is complete.

What OEM belt number does the Gates 50R4289 replace?

It replaces Polaris OEM drive belt 3211202. The equivalent Dayco part is XTX2288.
