I’m looking for ideas and any help yall might be able to give me. I’ve ordered a Bent FabAz Elite xl diy chassis for my build just waiting on it to come in. I’ve got an 06 F450 front axle with 8 lug UB on it it should be about 74wms from the research I’ve done. The problem I’m having is I’m setting it up for 50deg steering and I’m wondering if anyone else has accomplished this on thier rig. Just seems like it will be really tight with the pinion in the way of the link. My buddy has the exact same chassis but his is fabricated chassis stuff so it’s not much help for me. It’s got about 4 inches of tube showing on the driver side I’m just curious if y’all are using the angled link mounts or is straight fine

Triangulate your lower links, mine are maybe 16" separated at the chassis. Uppers can then "splay" slightly, a few inches narrower at the axle versus the chassis.
IMO, front geometry is more about setting your roll center and anti-dive values, and ensuring your combined triangulation hits/exceeds the combined 45 degree recommendation. (I think it's 45, more is always better for joint life)
IMO, if you really want 50deg steering, your going to need to go to a custom housing. Using the superduty axles, the diff is just too far over to the left. You really need to move the diff to the right some in order to get the link to move in a bit to allow the tire to swing to 50deg. You can triangulate more, but I found that doesn't do as much as people think it does and you wind up hitting the pinion with the link.
I'm building an f250 axle and shooting for 45deg steering angle. Its tight! I had to grind away the one rib on the the left side of the diff casting and move the link mount as close to the diff as I reasonably could.
Somewhat bad pic trying to show pinion to link clearance issues. This is for my build and my links clear, but land about 26" apart at the subframe. If I triangulate them anymore they'd be getting real friendly with the pinion yoke.
This is honestly where my train of thought has been leading me I’m just in the superduty cheap but it has a ton of problems. I think hearing it from someone else is what I needed. I have a 14 bolt I may just make into a a front diff and a Dana 80 I can use for rear steer
Its a good bang for you buck, but yeah, its got its issues. I'm just using it because either way I can't afford blingy custom shafts or housings at the moment. I did do a lot of design work to make it all work out with 45deg steering and 14" coilovers. If money was less of an issue I'd go other directions.
Agree 100% the only thing I’m out right now is a set of 35 spline lockouts but I could probably still reuse those. Ideally I’d prefer portals but I ain’t got portal budgets. Heck I don’t even have spider track budgets
