Rzr highlifter belt slip

I have a 16 RZR High Lifter in the shop. At about 50 mph the Rev limiter is being tripped because they are telling me that the belt is slipping. They say that Polaris says that this is because of the High Lifter being built for mud and not racing. With the 32 tires and the torque, it is causing the belt to slip. Well, I was not racing I was just driving. It’s in for its first service and already the belt is glazed. They tell me that the only way to correct it and not have it slip at high speeds is to do a clutch kit. However, one won’t be available until late spring or early summer. Thoughts on this BS?
