Anyone have the instructions to do this?
I got my 149 setup with the pig hards and they’re good but I kinda prefer the stock orange cranked down cause you know
Pulls the hangar back and has a tight setup but soft bushing thing going on where you still get some lean but it’s tight so you can pop straight up with no effort
There is probably a simple process with exactly the right tools in a machine shop or something, but an angle grinder does a fairly solid job for me, maybe without it looking quite nicely finished and professional, but if I tried I could definitely make it look very close to that.
Before going hard at it, I would say to have a go on some older / almost worn out kingpins first, but in general, have everything on the setup where you want it, truck all mounted, bushings how you like them and see how much kingpin is sticking up.
Then with the grinder just do a bit at a time, some from the left, some right, etc so you are not heating the kingpin too much (which can cook the bushings to bubbling point) but ever so slightly rounding it off as you go. Even do one for a bit, then the other for a bit, to give it time to cool, but I usually did up to three threads on each in maybe five or so minutes without issue.
As long as you round the kingpin heads a bit as you go, the nut will still easily come off and go back on fine too, but you can take it down to just above where you want it easily, giving you more kingpin clearance on any truck.
I did this a while back, for show and tell:
