Swapping out king pin

Just a word of caution.
Find out how much deeper the replacement pin box/kingpin is from your stock one. In all likely hood the replacement will be deeper than your stock one, which in turn will raise the front of your trailer. Could be as much as 4" to 5" difference. If you have adjustment in your 5th wheel hitch to compensate for this, then great.
Reason I know is because I found this out after I bought and replaced my pin box with a 5th airborne. It raised the front of my trailer alot which really affected the ride and handling.
Good luck.

Thanks. I plan to do some before measurements of height above truck rails etc. and then match. As best I can....
