Dayco XTX Extreme Torque Drive Belt for Arctic Cat ZR 9000 Thundercat 2018-2020 XTX5063

If you're running a high-output Arctic Cat ZR 9000 Thundercat and expecting consistent power delivery, your factory drive belt is likely the weakest link in the drivetrain. The DAYCO XTX5063 is purpose-built for extreme torque applications, delivering the grip and thermal stability needed to handle aggressive throttle inputs without slipping or degrading. This belt unlocks the acceleration and engine braking control your sled demands at sustained high RPM.

The XTX5063 uses a hybrid cog design—deeper teeth on the driving surface paired with rounded cogs underneath—that maximizes grip under load while reducing friction losses. You'll notice sharper throttle response off the line and smoother mid-range acceleration, especially on hard snow or demanding terrain. The advanced polymer construction resists heat buildup, keeping the belt cooler and extending service life even when you're pushing the sled hard.
