How to Install a Vented Full Windshield on Can-Am Commander

Quick answer

Installing a vented full windshield on a Can-Am Commander or Maverick Sport Trail takes about 30–45 minutes. The key is to align the mounting brackets loosely first, then tighten evenly to avoid cracking the polycarbonate.

Installation steps

1. 1. Prepare the mounting area: Park your UTV on level ground and clean the roll cage or frame surface where the windshield mounts. Remove any existing brackets or accessories that could interfere. A common mistake is skipping the cleaning step—dirt or old adhesive can prevent the brackets from seating flush, leading to rattles or uneven pressure.
2. 2. Attach the mounting brackets loosely: Position the left and right mounting brackets on the roll cage. Insert the supplied bolts and nuts but do not fully tighten them yet. Leave about 2–3 mm of play to allow for adjustment. Tightening brackets too early often misaligns the windshield, forcing you to redo the work or risk cracking the panel.
3. 3. Hang the windshield on the brackets: With help from a second person, lift the windshield onto the brackets. Align the pre-drilled holes with the bracket slots. Insert the remaining hardware (screws, washers, rubber grommets) by hand. Do not force the panel into place. If the holes don’t line up, loosen the brackets slightly and adjust. Polycarbonate can crack if you overtighten or bend it.
4. 4. Level and tighten all hardware: Check that the windshield sits level from side to side and sits flush against the roll cage. Starting from the top center, tighten each fastener in a crisscross pattern. Work your way down to the bottom brackets. Tightening in sequence prevents warping. Over-torquing is the #1 cause of stress cracks—use hand tools only, not power drivers.
5. 5. Test the sliding windows: Open and close both sliding windows several times. They should move smoothly without binding. If they stick, slightly loosen the window track screws and reposition the window pane. If the windows are stiff after installation, check for debris in the tracks or an overtightened bracket that is distorting the frame shape.
6. 6. Final inspection and cleanup: Wipe the windshield with a microfiber cloth and a mild soap solution. Remove any protective film from the inner and outer surfaces. Check all fasteners are snug (not tight) and that the windshield does not vibrate at idle. A loose fastener may cause rattling later, but a too-tight one can crack the panel during temperature changes. Recheck after your first ride.
