Ultimax UA426 is a CVT drive belt for Polaris ATVs that replaces the original part number 3211113.
The belt is a wear part and the heart of the whole drivetrain: it transfers power from the engine to the transmission and so affects how the whole ATV works.
Replace the belt whenever needed so that your ATV keeps moving and working properly.

Professional tip for installing a CVT drive belt
We recommend "breaking in" a new CVT drive belt. After replacing the belt, ride about 3–5 km at a brisk pace without load or constant acceleration, so that the belt heats up properly. Then let it cool down for a few hours, or until the engine feels cold.
This helps the belt's durability and service life. Don't start pulling heavy loads or racing around town right after installing a new belt.
Will this fit my Polaris ATV?
