Ultimax 144-4353U4 Ultimax Pro Belt - 1 15/32in. x 44 5/8in.

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.
