Traction When You Need It SuperATV™s SwifTrac Differential is the locking front differential your Can-Am Outlander needs. It uses a sprague carrier instead of a slow working clutch pack to give you the traction you need instantly. Get more power to the ground® with SwifTrac. There™s no more spinning your tires when you get stuck. This complete differential comes fully assembled”just remove your Visco-Lok differential and bolt on SwifTrac. Fill it with oil and get rolling. Why You Need to Ditch Visco-Lok Can-Am™s stock Visco-Lok differential is not the locking differential you want. When you get stuck, your wheels need to spin at least one full rotation before the clutch pack will engage and lock the diff with Visco-Lok. By then, you™ve already lost your momentum and then the diff can slip. SwifTrac Uses a Sprague Carrier SwifTrac utilizes a sprague carrier to engage and disengage the diff lock automatically. With four-wheel drive engaged, this differential uses the sprague carrier to lock instantly as soon as traction™s needed and unlock when it™s not. No wind up and no delay. You can cruise through trails at full speed and get torque to the front tire that needs it most instead of spinning your wheels. You don™t have to think about it, it just works. Maintain momentum as you ride instead of getting stuck and waiting for your Visco-Lok differential lock to engage. It™s the Visco-Lok replacement differential you™ve been waiting for.

It comes complete with gears, hubs, bearings, seals, hardware, and everything else you need all preinstalled. The only thing missing is oil and your UTV.
