The new Aluminum Trackshaft and Superlite Brake Rotor Combo from Speed Shop is 5.5 lbs lighter than stock.
The trackshaft is a direct replacement for the stock shaft, but 3 lbs lighter. The Brake Rotor is more than 2.5 lbs lighter than the stock solid brake rotor and 1.5 lbs lighter than the stock vented brake rotor found on some Sno Pro models.
The combo fits 2012-19 Arctic Cat models, both standard and reverse style gearcases. The reverse model has a wider spline on the chaincase side.
It also fits Yamaha Sidewinder and Viper models 2014 to present.
The BDX shaft is 20 percent stronger than Arctic Cat's stock aluminum M 8000 trackshaft. You can see in the Speed Shop cross section that it has five support webs instead of four like the OEM version. No extra nuts or spacers are needed to use the Speed Shop shaft either, like the OEM M 8000 shaft. The BDX shafts are hardcoat anodized, so it even looks like a stock steel shaft. It is very strong and can easily handle plenty of turbo horsepower.
The shafts are also available with the drivers installed with several options. The MSRP is $259.95.
