Pin Box Contacts Truck Bed on Tight Turns

[Lenny_K]

When I turn sharply the rear of the pin box will make contact with the top of the truck bed.
The rear of the pinbox has already been cut on an angle so I'm thinking of cutting it more. This would be very near the bottom hole that would be used if the pin would be lowered.
Has anyone else have this problem and how did you solve i?t

Thanks Chris. I'll have a go at it.

Pin boxes come in different lengths and I solved that issue by changing to medium length pin box from a long. Medium was 10" shorter than long. If anyone needs a long Trail-Air contact me. Randu

I used a sawsall. The metal is not harden and cuts fairly easy. I had lots of extra holes and trucks are getting higher not lower. I did cut through the stamped in serial number. Saved that piece. Person that purchased trailer in the spring did not have to adjust the pin box.

When I was looking at my pin box the other day I had looked at following the same line you did but was worried about cutting away the bolt holes. Looks like that didn't bother you any.
What did you use to cut it away. You said sawsall time, but with the one I have it would take forever.

Thanks bpounds. It seems like cutting is my only option.

Unfortunately the pin box is raised up all the way already so this isn't an option.

Sawsall time.

Somewhat common problem. I would cut it, if that would eliminate the contact, AND as long as the cut was outside the contact area of a bolt head.

You might also consider raising your fifthweel hitch, and raising your pinbox an equal amount, if those adjustments are available.

But bottom line is, it is no big deal cutting the rear end of the pinbox. People get all worked up about how critical that thing is, checking their torque all the time, insisting on grade 8 bolts, and in general just fussing and worrying. I guess they don't understand the mechanics of it, and fear what they don't understand.
