It can be adjusted up. There's a bunch of adjustment holes on the swingarm mount for the wheel mount to move up and down on for wheel/tire height. There's also an in and out adjustment for wheel/tire width.
The hardest part is getting the spindle set in the correct spot and orientation in conjunction to the landing plate. The different pivot points of the door vs the swingarm make it difficult to get just right. If you tighten the turnbuckle too much, you don't get a full open before it binds. If you loosen (lengthen) the turnbuckle you get full openings but it sits too far away from the landing plate (when closed) and will vibrate while driving.
Lots of trial and error but fully doable. My buddy and I barely have any welding experience and were able to get a fully functional install done. Just slowly dialing it in. Internal bracing of the door is recommended after having it for a few months now .
