The Big Boy Power and Speed Kit is designed to help you get the most out of your stock sled. It includes everything you’ll need in one package. We give you different gearing options as well as a Tunable Exhaust for best performance. You can easily set up a stock sled with the power for the hills or speed for lake crossing or trails. This kit fits the 2010 and newer Arctic Cat and Yamaha sleds with the Yamaha Engine.
This kit will typically help you gain 6-12 mph from stock speed.
