We have several replacement air ride pin boxes that will fit in place of your Fabex 520 pin box. For an 18,000 pound capacity I recommend the 5th Airborne model # 5AB-S500-700. It has the shock and air bag to reduce 5th wheel trailer chucking.

And if you have a short bed truck and need more turning clearance I recommend the 5th Airborne Sidewinder # RP61412. It is rated for 16,000 pounds. It also has a shock and air bag but also moves the pivot point of the trailer back 22 inches for turning clearance. I have included a couple of video links on this pin box for you.
