Offroad Trailblazers and Envoys

Alignment with tire size change

Need new shoes? This is the place to discuss.

Ok so every tire kingdom I've went is afraid to touch my 34s... The only one that came close to doing it said they would have if they had a larger machine to fit the tires on..
If I put on my old 32's and get it aligned and then put the 34s back on it should be fine right?
I have a 3 year alignment from tire kingdom so I'd rather not go to an offroad shop to do this

Suspension geometry doesn't change when you change wheels or tires. You should be good.
11 Silverado LTZ - 6.2L/6l80, 2/3 drop, self tuned
85 Hilux - 3RZ, dual cases, caged, 40s, chromo everything
02 TrailBlazer LTZ - 35s, lockers, balls - Gone but not forgotten - Build

Ok how do you adjust the camber on these vehicles? All the alignment places I've been going to say they can't do it..
I have 86 springs (~1.25" lift) and marks full lift (~2.75") up front and flipped UCAs...
The flipped UCAs should be what gave me the positive camber correct? If I have to I'll flip them back to get everything aligned again, but I'm also happy with my ball joint angle right now so I don't want to flip them back unless I have to.
But could I also just add more lift up front (in the form of another shim outside the strut) to help bring my camber back to normal? I believe I have enough room for another 1/2" shim.... If not I could cut something out of cutting board to 7/8"...
I'm 2wd, so I won't have to worry about CV angles with 4.5"+ of lift up front, but is there anything else I should be worried about with this much lift?


I was under the impression that the lower control arm bolts were slotted so that the LCA would be pulled out and tightened to adjust camber.. but I guess not

These goofball alignment shops must think we're like Hondas or those lesser vehicles.
