Lifted truck alignment specs
I’m sitting at between 3 and 4” of lift and on 35s. Crew cab short bed. Curious what anyone else with that level and tire size uses for specs. Currently I’m at 1/8” toed in, -.5 camber and 4* castor. I could get another degree of castor with ballpoint eccentrics but it would really have the joint stressed and I don’t want to do that. Debating shimming the leaf springs to 6 degrees. Anybody run 6 degrees? I’m looking for highway stability towing and it’s just not where I want it right now. Yes, I am picky.

Sounds similar to what the Excursion guys have been doing:

Have a similar set up have always ran dead ahead 0.00 for the toe spec. Camber and caster I couldn’t recall of course they show up out of spec compared to factory. Truck drives great and tires last 50-60k. Some
shops have suggested toe in to work with the crown of the highway. Personally not a fan seems to me that’s more for medium duty/tractor trailers. Have you recently inspected the front end in the air?

I'm currently sitting at , measured from center of hub to top of fender arch , 26 1/4" front and 26 3/4" rear , running 37" tires, and I'm sitting right at 5.5° . I've had this truck (2000 ex 4x4 7.3) for 21+ years, 549k miles, and it never driven this nice down the road.
Also, I tow every day, skidsteer, mini ex, heavy dump trailer, etc and she drives beautifully.
