Tires and Suspension Question

[Jeeperjamie]

So I got a question as far as getting suspension lift from adding tires.Should I treat that type of lift the same as I would as adding say 1.5" of extra lift by way of adding a spacer. Let me explain a little bit. I had a 2.5" Spacer lift on my jeep, then I added rubicon take off front springs. With added winch and bumper weight I got I'm guessing that put me somewhere around 3 to 3-1/4 inches of lift. I just had 37 12.5 17 tires installed. I measured before adding the tires with 35" BFGs dead center on my Jeep ground to bottom of rubi rails I was at 20-1/4 inches. With the 37's I'm right at 22, so it seems like I got 1-3/4 inches of lift. As far as changing controls arms and track bars I feel like it's about time, I'm trying to decide if I want to go adjustable control arms or Geo Brackets. Any help would be appreciated.

No. Tire lift does not affect geometry.

I think it is time to get control arms and track bars at a minimum. I also am a big advocate for at least a rear track bar bracket to help roll center.

Im also a big fan of geo brackets. Unless you’re a big time rock crawler, the anti dive you get from them is a big benefit. And (at least with AEV) you’re no lower than your rear frame LCA mount.

both, if you want a great driving truck. I did do 3.5" springs with adjustable lowers and it road like a tank.. Here we have terrible roads and locally lots of rr crossing.. I added the geo correction bracket last weekend and wow what a difference in ride quality. It is not my DD, I was ready to sell it.. Now I'm starting to enjoy driving it.. Going to JWJ tonight which is 45min drive and I'm looking forward to the trip

edit: ^^^^^ I followed @KurtP lead on trying to fix mine.. seems to have been good advice! Thank You Sir

I appreciate that and I was thinking that also. I had the AEV geometry brackets on my jku and had everything dialed in suspension wise before adding 37s so I wasn't sure how to gauge it. I guess I'm going to grab a adjustable track bar and some Geo brackets because I'm not planning on going any higher suspension wise as far as lift.

I just ordered some core 4x4 t4 adjustable lower front control arms. I figured that's a good place to start and I'll get the rears and uppers prob in the summer. Are the geo brackets for people with non adjustable control arms and track bars or does it benefit having them both?
