THE MUD MONSTER BELT BY GBOOST (MMCA**) IS THE BELT WITH ULTRA GRIPPY COMPOUND TO REDUCE SLIP AT ALL COSTS FOR LOW SPEED VERY HIGH LOAD SITUATIONS. 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
