If you're looking to give your ATV extra pulling power by increasing torque then a gear reduction kit is the way to go!While an ATV may be a great performer on the trail with stock tire height, when larger mud tires are added for use in extreme conditions this can often leave a performance enthusiast wishing for more low end grunt. You can overcome this problem by using a gear reduction kit. A reduction kit is designed so that a stock ATV can turn the larger more aggressive mud tires without additional costly engine modifications. Once you install a gear reduction kit the motor doesn't have to work as hard to spin the tires which means it won't draw as much current from your batteries while it simultaneously increases torque to provide you with the traction and pulling power that you need.The system requires approximately 4-5 hours of labor by an experienced technician to install and is furnished complete with pictures and instructions. After installation, the RPM will be slightly increased, even with oversized tires. Tests have shown this increased RPM has not been objectionable. Gas mileage is essentially the same as the machine would get without the gear reduction system and with oversize tires installed. This product is carefully machined and heat treated for durability and long life.15 1/2 percent reduction
