Which Replacement Pin Box for 5th Wheel with Fabex 520 Pin Box

Question:

I currently have a Fabex 520 pin box on my fifth wheel that I need to replace. I’m having trouble figuring out which model I need. Can you help me out with the models that are available?

To replace your existing Fabex 520 pin box I recommend using the Reese 5th Airborne # 5AB-S500-700, which will provide you with a smoother ride because of the Air Ride coupler. This will be a nice upgrade for your 5th wheel and has a 21k capacity, so it'll work on most applications. If you need a rotating turret pin box then you can use the 5th Airborne # RP61412, which has a 16k capacity. Both of these pin boxes are compatible with a Fabex 520.

I've also linked some review videos of these pin box replacements for you to check out, as well as our entire selection of Fabex 520 pin boxes for you to check out if you're looking for something different.
