3.5" Lift, Wheels, & Tires Question

I'm taking my '10 4 Door Rubicon to the shop tomorrow to get a 3.5" AEV lift put on. I have 37x12.50x18 KM2's mounted on ATX 18x9 wheels. Once the lift is installed should I run it with the stock tires to make sure nothing is wrong, no shimmies, steering issues etc? The guy at the shop said that all the geometry, camber, toe, pinion angle, alignment etc. will be set and everything the same with the stock wheels and tires as with the aftermarket ones. So it really wouldn't matter if he mounted the new wheels and tires when he's done with the lift. Is this accurate? Sounds fishy to me. I've got the tires mounted and balanced already and I have a small shop and equipment to bolt them on myself.

I'm just thinking if something isn't right with the lift and I had the stock wheels and tires on it then it would take one less variable out of the equation when trying to track down what is wrong.

Opinions? Helpful hints on the AEV lift/wheels, tires? Any other general advice would be appreciated!! $350-$400 is what the shop said it would run to install the lift. That about right? Thanks!

Stock wheels will not fit.
Too much backspace.

Heh...you'd be getting a steal if they install it for $350-400, honestly. I did it in my driveway and know how long this kit can take to install...especially if you hit problems...Of course, that was with mostly hand tools and jack/jackstands...but still.

Anyways, yeah, what he said...stock tires won't fit. Just mount the new ones and you're good to go. Kit's pretty straightforward, and I'm not sure how they'd fuck it up...

They should fit if he still has the stock tires on them. I drove my RK 3.5 inch lift for about a month waiting for the tires/wheels to arrive. It's a toss up. Might be nice to have it all done, but as you mention, if he installs the lift and you have any issues with stock wheels/tires he can't tell you it's because the tires aren't balanced right.

Side note; not saying this to be a dick, but consider installing the lift yourself. It's easier than you think, you will save the $, and then you will be more familiar with it when there are problems down the road. Prior to JKO I wouldn't have installed my own lift, but after reading some info here I decided to do it and it was not nearly as difficult as I expected. Good luck either way.

The price to install sounds right. Your new tires will be fine to install after the lift. The kit is very well designed i think you will like it im running the same one and wheel the hell out of it.
? Did you get the steering upgrade? If not i would recomend it at least as soon as you can. It will flip your steering and give you a better dampner. Help with bump steer by lining up with your tack bar.

OK, maybe the AEV kit is more challenging than the kit I installed. I will defer to Jagr's advice as he installed the same kit..

If you have a weekend I would do it yourself. Its not hard i did mine and it was the first one i ever did. Just do some research on here and you can save $$. You can also check out the directions on ther AEV website
Youll need jack stands and 2 jacks and some wrenches and maybe a cargo strap.

ahhhh why wouldn't his stock wheels and tires fit? Of course they would fit. I think what everyone is thinking...That you might have bigger tires on your stock wheels. But that doesn't seem to be the case...sense you mentioned new wheels.

X2 they will work because they worked before, its the new tires and wheels that might have an issue

Thanks for the advice guys!! I did get the high steer kit upgrade.

I was planning on installing the kit with the help of my brother as he has the shop and hand tools to do it. He doesn't have pitman arm pullers, or specialty tools, etc AND there was a problem with space and availability in his shop. So I'm kind of at his mercy. Had the kit for 2 weeks now and still waiting, so I said screw it and I'll chuck out the $350-$400 (hopefully they don't try to screw me outta more) and go ahead and get this shit on as to salvage the rest of the summer weekends!!!

Obviously, I'll tell the shop not to cut or clearance anything (fenders, rails etc) without calling me. Another issue that I want to ask them is if the can do the alignment with the stock wheels and tires so they don't have to hang their alignment tools off my new wheels and scratch the piss out of them. This happened to my brother with his brand new wheels...he wasn't a happy camper!!

If everything can be set up and I can drive 45 miles home on the stock wheels and tires, then I think I'll do that. Just to make sure that the handling and everything is dialed in. If not then there's one less variable to consider. THEN I'll bolt on the new wheels and tires.

If I need to have them set it up with the aftermarket wheels and tires then I know that the Rubicon rock rails will have to be trimmed down and possibly cut and re-weld the pinch seam (it's a 3.5" kit with 37's), but I can do this at my brothers shop. Will the 37" KM2's fit just to drive it home on the highway without getting into the rock rails? Or will I need to have the installer remove the rock rails?

Sorry for the length and all the questions. I just want to make sure I have all the bases covered! Thanks fellers!!

You'll be fine, put the 37s on it and go! AEV is one of the best lifts out there.

You'll almost definitely need to trim pinch seam/rock rails in order to fit the 37's even on the road. I have the 3.5" kit with 35's and they barely clear... and I've talked with several guys running 37's on the 3.5... I know they all had to trim to clear.
FWIW, I love my kit. I definitely hated the cam bolts on the front, but I installed the kit with my dad, so maybe we didn't install them properly. Anywho, I got LCA and have no complaints whatsoever now. You'll love the high steer kit.
Congrats on the lift.

The new version of the lift includes brackets that lower and move the LCA forward and also drop the UCA to restore geometry and caster. The same bracket works for 3.5" and 4.5" lifts, but with different attachment points (ie, you use different holes in the bracket for the different lifts.) They got rid of the cam bolts sometime this spring.
