Description
The Ultimax Pro Drive Belt delivers measurable improvements in acceleration and clutch engagement by reducing slippage across the full RPM range. A thicker cross-section and advanced cog design mean more consistent power transfer and cooler operating temperatures, which directly translates to longer belt life and more predictable performance on the track or trail. If you’re running your SRV 540 hard, this belt is engineered to keep up.
