Troubleshooting Fifth Wheel Trailer Pin Box that Hits Bed Rails Around Corners

Question:

I have been hitting my truckbed with the bottom flange of the 5th wheel arm at 60 degrees. I cannot raise the ball on my Anderson gooseneck high enough to clear the bed sides turning past 60 degrees. Do I need to buy a 5th wheel with a steeper linger arm assembly? Or what?

What's your bed rail to trailer overhang clearance currently? It needs to be 6 inches to ensure that you don't have clearance issues. You also need to make sure the trailer sits totally level as well. If you need to raise the trailer suspension so that you have the clearance needed without bed rail interference you could use an axle over-under kit to accomplish this.

The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter you could use the Over-Under Kit, # K71-384-00. These kits can be installed without welding but the manufacturer strongly recommends having the new spring seat tacked in place on the other side of the trailer axle.
