Spent the day installing my new Liftmaster 8500 Jackshaft garage door opener. Some people call it a sidewinder because it mounts right next to the torsion bar, allowing you to remove the center track and motor from a traditional opener. The opener in our garage was really old and too low to let the X's FWD open fully. On the passenger side it could only open a fraction of the way. A real pain in the back when trying to lift my sleeping 7-year-old daughter from that side of the car. If any of you have a low garage door opener and can't open the FWD on the X, I highly recommend getting one of these. Also, it just opens up the whole space and feels much better.
