EVP Bad Ass Drive Belts for 2020-'23 Polaris RZR Pro XP & RZR Turbo R

EVP Bad Ass Drive Belts for Polaris RZR Pro XP and RZR Turbo R models offer far-superior performance at a lower price point than OEM belts. For years, EVP has been working directly with GBoost Technology, a highly regarded CVT belt and clutching manufacturer, to validate many new belt compounds for SXS’s and Snowmobiles. Each compound gets subjected to an extensive durability regiment through our sponsored race program and on our own big-horsepower vehicles. Besides being more durable compared to OEM belts, Bad Ass belt compounds provide better grip, which transfers more power to the ground instead of excess belt dust. Furthermore, GBoost is one of the only manufacturers that designs belts for different uses and conditions for the same vehicle. 

XR RACE SERIES: Developed specifically for race applications or high-powered cars that thrive on thrashing through the dunes or desert. Manufactured with a larger Kevlar cord and custom braid design marrying the belt layers for better shock absorption, increased cord pop-out resistance, and being able to withstand more heat for increased strength and durability. This belt has been load-tested to withstand the power of 600hp machines and is considered the best and strongest all-around CVT drive belt we offer.

• Built to decrease the chances of snapping or delamination in race applications when the tendency is to land on the throttle
• Manufacturing, quality control certifications =-ISO-14001, ISO-9001, and IATF-16949.
• Newly released design that has a larger Kevlar cord with a custom braid design to act as a shock absorber.
• New vulcanization process to marry the layers of the belt together around the cord preventing premature separation of the layers.
• Custom blend of two premium High Modulus Compounds holding the top layers together with the cord and bottom layers like super glue!
• Highest shock load rating to date being able to withstand the power of the 600hp machines.
• Increased top cog pressure load design that increases sidewall rigidity, prevents top cog bowing, but still allows for increased rotational flexibility.
• Bottom cog uses high-modulus rubber compound (BZX1) for better heat resistance and heat dissipation.
• Impregnated with short Aramid Fibers for better belt-to-sheave adhesion and reduced overall belt temperature.
• Latest bottom cog design for greater rotational efficiency at full shift.
• Precision ground sidewall angle (SCUFFING) for smooth engagement, increased power transfer and lower operating belt temperature.
• Kevlar cord, versus polyester, wraps over bottom cogs for increased bottom cog strength.
• Increased cord pop-out resistance.

WORLD’S BEST BELT: The toughest, best all-around belt proven repeatedly in the most extreme conditions! EVP World's Best (WB) Belts are for the rider/racer that is looking for a tried-and-true belt that’s better than OEM with proven performance. Third-generation heavy duty, high-twisted aramid fiber cord is used for high-horsepower machines, making it the strongest belt on the market next to our XR Race Series belt and surpassing our Extreme Belt. The WB belt has a high shock load rating to withstand the power of up to 400hp machines. This belt acts like the OEM belt in terms of engagement and operating RPM’s.

• Manufacturing, quality control certifications =-ISO-14001, ISO-9001, and IATF-16949
• 3rd Generation heavy-duty, high-twist Aramid Fiber cord for high-horsepower tensile load requirements, making it one of the strongest belts on the market.
• Higher shock load rating to date being able to withstand the power of the 400hp machines.
• Increased top cog pressure load design that increases sidewall rigidity, prevents top cog bowing, but still allows for increased rotational flexibility.
• Bottom cog uses high-modulus rubber compound (BZX1) for better heat resistance and heat dissipation.
• Bottom cog is impregnated with short Aramid Fibers for better belt-to-sheave adhesion and reduced overall belt temperature.
• Latest bottom cog design for greater rotational efficiency at full shift.
• Precision ground sidewall angle (SCUFFING) for smooth engagement, increased power transfer and lower operating belt temperature.
• Aramid Fiber cord, versus polyester, wraps over bottom cogs for increased bottom cog strength.
• Increased cord pop-out resistance.

EXTREME (EX) BELT: Extreme performance and reliability. The EX Belt is built for the extreme trail/mud riders that need a ton of belt squeeze to stop from the belt from slipping and deliver enhanced response at all RPM levels. This belt changed our Wisconsin trail driving habits and allowed us to drive our vehicles to the limit without the fear of premature belt failure. The specific compounds in this belt make the engagement quicker while lowering the peak engine operating speeds by about 200 RPM’s.

• EX belts have been developed with a high-temperature compound called DUMAX for added strength, flexibility, and heat resistance.
• Ultra-strong Aramid Fiber cord that can handle/carry more than 10,000 pounds of tension without stretching or breaking.
• Higher strength compared to OEM and aftermarket drive belts
• Delivers exceptional 'belt squeeze' for more tuning possibilities and less slippage.
• Maximum under-cord stiffness allows the belt to flex for rotational efficiency and cooler running temperatures
• Built for high temps, extreme abuse, and excessive shock load.

MUD MONSTER BELT: Designed specifically for the mud rider that needs maximum belt squeeze to stop the slippage in the roughest terrain. The specific compounds in this belt make it instantly grab when the clutching and tune are correct. This blend of compounds and thickness will build more heat at higher speeds, so we recommend staying below 35mph. Mud Monster belts have been developed with the 2nd generation compound called Dumax 2 for added strength, flexibility, and heat resistance over OEM belts. This belt is built for extreme abuse and thicker for more belt-to-sheave adhesion.
