Need to mount or replace the windshield on your Ski-Doo REV XM or XS sled? This is the genuine Ski-Doo part (#860200944), not some flimsy aftermarket copy. It's the plastic windshield base that includes the colored trim piece. Hardware (screws/bolts) isn't included, so you'll need to reuse yours or get new ones. Super important: double-check your model and year to make sure this is the right fit for your specific snowmobile. If your old base is cracked or you're doing a custom setup, this OEM part ensures everything lines up perfectly and looks factory fresh. Keep your sled looking good and your windshield secure all season.
