Got a Can-Am Outlander 1000 or 1000R 4X4 from 2012 to 2018 with a blown rear diff? This Caltric Complete Rear Differential Assembly is here to get you back on the trails. This isn't just a set of gears - it's the whole differential unit, pre-assembled with the gears and internal parts already inside. That means you can swap out your old, damaged unit for this new one without having to mess with individual shims, bearings, and seals (though always check your service manual). It's built to be a direct replacement for OEM part numbers like 703500878, 705501896, and several others listed. The big advice here: before you buy, compare the photos of this unit to the one on your ATV. Make sure the mounting points, bolt patterns, and shaft splines look identical. This is a major repair part, so getting the right fit is crucial. If you're comfortable with wrenching on your Outlander, this complete assembly can save you a ton of time and headache compared to rebuilding. Get that 4x4 power flowing to both rear wheels again and get ready to ride.
