120 RACING CLUTCH AND GEARING KIT The stock 120's have a very heavy 40 size chain and sprockets which have a lot of inherent drag which hurts performance. The stock gear ratio is also designed to keep the sled down to a safe and often rather boring 7mph. This kit will cure that problem for good!
Racing Clutch-High Performance unit with 4 shoes and easy change springs for tuneablilty.It also features a higher engagement rpm for better take-offs. Includes Racing Clutch, Quick Change Sprocket Hub, Aluminum Sprocket and a #35 Racing Chain. Speed is generally in the 20+ mph range with these kits. Try one of our Intake Kits or Governor Springs for even more mph and horsepower.
BE SURE TO CHECK OUT OUR NEW GOVERNOR SPRINGS ON THE ENGINE PAGE ECONOMY SPEED GEARING KIT
Not Racing? Just want some more speed for play around the trails? Then this kit is ideal for you! Includes a new 13T clutch drum to convert your stock 40 size chain over to the preferred 35 size. Also included are a quick change hub, Aluminum sprocket and chain. Simple bolt-on installation will get the speed up close to 20mph. For even more speed try our Intake Kits or Economy Performance kits that include a stronger governor spring.
HEAVY DUTY CHAIN TENSIONERS
HIGHLY RECOMMENDED TO KEEP CLUTCHES AND CHAINS FROM WEARING OUT!! This manual chain tensioner is easy to install and elminates the factory spring loaded tensioners on the Arctic Cat Z 120 and the Ski Doo MiniZ 120 models which unfortunatley never works all that well. This tensioner constantly keeps proper alignment and load on the drive chain under hard braking and acceleration which is very important when trying to reduce chain wear and clutch slippage. Includes a CNC machined aluminum bracket that easily bolts to the side of the tunnel and a ball bearing type sprocket for accurate chain tracking. Tensioner kits are available for our 35 chain conversions as well as the stock 40 chains. Polaris sleds already have a slot on the tunnel, so only the sprocket is needed and it's a great upgrade from the stock roller which often gets grooved causing the chain to run off the sprocket.
