Mud Monster Belt Line


This belt is built specifically for the straight mud rider that needs a ton of belt squeeze to stop from slipping the belt. The specific compounds in this belt make it instantly grab when the clutching and tune are correct. Note: This blend of compounds and thickness will build more heat at higher speeds, so we recommend keeping it under 35mph.


  • Higher strength compared to OEM and aftermarket drive belts.
  • Mud Monster belts have been developed with the 2nd Generation compound called DUMAX2 for added strength, flexibility, and heat resistance.
  • You can squeeze this belt a lot harder for more tuning possibilities and less slippage.
  • Maximum under-cord stiffness allows the belt to flex for rotational efficiency and running cooler temperatures
  • Built thicker when possible for more belt to sheave adhesion.
  • Built for extreme abuse, and excessive shock load.
  • Handles higher temps than OEM
  • Built with Aramid fiber cord to eliminate stretching like a Polyester cord.
  • Made in the USA!
  • Replaces OEM# 3211186
