Ultimax 138-4400U4 Ultimax Pro Belt - 1 7/16in. x 44 13/16in.


Generally ships to addresses in the contiguous United States the same business day if ordered by 12:15PM Central Time!

Ultimax 3 has evolved into Ultimax Pro.
Belt features a thicker cross section so more surface area contacts the clutch; this means less slippage over a broader speed range for quicker acceleration.
New cog design dissipates heat and aids flexibility.
Cooler running belts mean better performance and longer lasting belts.
Run cool, run long, run fast with Ultimax Pro.
