The World’s Best Belt is the ultimate all-around performer. is the ultimate all-around performer. No matter what you’re doing, this belt will pull you through with smooth engagement and excellent heat dissipation. The superior compound is designed to retain cord rigidity for better grip and less slippage, which leads to a longer life, even when you’re pushing your Defender hard. The aramid fiber cord gives it an ultra-high shock load rating.
Extreme Badass belts are for those that like to gear down and go big. If you go low and slow through deep mud and rocks, and you roll on big tires, this is the belt you need. It uses an aramid cord and high-strength rubber compound that are designed to get squeezed harder by your clutch and handle high torque pulls without breaking.
Badass XC X-Country
If you’re looking for an OEM replacement that won’t break the bank, look no further. The Badass XC X-Country disperses heat faster than an OEM belt and engages smoothly for better performance.
Mud-specific machines call for a mud-specific belt. That’s why the Mud Monster Belt exists. It’s designed to get you through the thickest bogs and drags with ease. This belt offers more tuning possibilities and less slippage because we know mudding is all about the grip. It also utilizes an aramid fiber cord to eliminate stretching.
With Mud Monster, you can go full send in the deepest mud hole, no-holds-barred.
NOTE: Mud Monster belts are designed for extreme grip and build heat quickly over 35 MPH.
Cruising the dunes and desert with the pedal down has always been hard on stock belts, and that’s what Sand Storm Belts are built for. They love high speed, high RPM, and high heat. Why? Because they have amazing heat dissipation—they run cool no matter what. So ride hard, Sand Storm will keep you running smooth and the aramid cord construction will keep it in one piece.
