Yeah I can't wait to measure it 30 more times while slowly adjusting the UCAs. First I need to build some adjustable arms. I actually picked up a UCA the other day so I could give it to my fab guy and have him build me a set of super beefy boys.

the uppers need to offset, building a set of lowers would probably be easier
Spohn sells them as a full set or separate if you want to get an idea

Yeah I have their boxed and bushing lowers which are nice but I've seen some issues with the uppers and would like to avoid spherical joints if possible. Theres a guy in PT.net that built himself a set for his H2 rear swap in a Tahoe. He said he can make me a set but I'd like to source them local if I can to save shipping and be more hands on.


His are 3/4 plate boxed with a ruff stuff rod end on one side and a bushing on the other.

Dropped the rack caps and appliques off at a paint shop this morning. Guy quoted me $200 which seems fair, I suppose I was hoping for less but I guess 6 pieces is a lot of little pieces to mess with.

Yeah I’ve heard of those Spohns failing under high hp applications.

I plan to get new stock lowers and extend them to center the axle in the opening. I'll use the originals as splices/fish plates and box in the underside. I plan to build some adjustable uppers with some poly bushings I already have on hand, scrap DOM and some tube adapters and bushed ends from a suspension fabricator supply (Barnes 4WD, Ballistic fab, Rusty's, etc.)

Ok so the front appears to be at 5* downwards. View attachment 253938

You need your pinion to be pointing up around 3 degrees.

Of course, these numbers will change if you move the truck elsewhere. If you do, just re-measure the front and make the rear pointing up at the trans about 2 degrees less.

Cool! I thought it was exclusive to the higher trim models- Denali, Esky, maybe Z71, etc. That opens up the possibilities.

My local yard is an LKQ U-pull-it, so they don't keep note of specifics such as trim around glass, etc. I give 'em $2, pass the turnstile and the hunt is on! They're decently well-organized so I just head to the sea of fullsize SUVs.

I wish I had a decent yard here! They’re all terrible. And hardly an NBS or NNBS can be found. [emoji19]

Same here.
