AEV Vs. Rancho Geometry Brackets

Putting on RK 1.5" coils on my 2 door so expecting up to 2.5" lift. If I add the brackets, which one and why that one?

Some folks prefer the Rancho because they are thicker.

The AEV are lower cost and from experience the AEV hold up just fine unless you are going to use them as rockers.

Either one is a good choice.

Like Spin said .. They both do the same thing. AEV's give 3 locations based on lift height. Rancho's only have 1. If you read towards the end of the thread. You'll see guys with 2.5 posting caster numbers.
Seems the 2.5 (actual height) guys are getting higher caster numbers with the Ranchos. Why ?
Well looking at AEV's 2.5 hole .. It's set to drop caster not increase it. Remember, the 2.5 hole was added as a revision later.
@ 2.5" slightly higher caster is a good thing. Me .... I can't be running no 5*-6* at 4" of lift

The Rancho's are built stronger and install is a bit easier. I get at all this in the thread.

Ken - I called RK today just to confirm lift height on the 1.5's for a 2 door. They said I should expect about 2.5". That being said, should I just order the Ranchos instead of waiting to measure the lift like I was going to do? Also, on a 2010, will I have to cut a bolt off or do something with the exhaust? Sounds like a PITA.

Ken - on a live chat now with Quadratec. Their rep says:

"You only need those for a 3-4" lift".

I said:

" Not according to Rancho. It is listed for 2.5 and up. There has been a large discussion about this on Wrangler forum of which a Rancho rep is one of the participants."


They said:

"My 2010 is lifted 2.5" and I do not have control arm brackets. You do not need them, but I suppose it wouldn't hurt".


Why the differing info from them?

Most people get them to fix handling issues from low caster angle,

Did he say if he owned a 2 door or 4 door ?
2 doors -from my own experience -are a little harder to dial in ride wise. The longer wheelbase of the 4 door makes for a smoother ride
. My 2 door for example is finicky when the roads get crappy. A 4 door would handle the same road better.
Back to the brackets ... Will you "need" them ? Prob not for caster alone.
Will the brackets better overall handling on a 2 door which is a 100% daily driver. My opinion .. Is YES.

Plus we are only talking $100 -$125 . I'm fighting the urge to regear $2200

I was thinking you owned a 12 +

Yes you do BUT... The 1/2 bolt is included with the Rancho kit.

Do you have a sawsall ? The bolt is easily cut with the right tool.
Don't try and use a hack saw like we did lol
I've seen people pry the exhaust away. That looks like a pain in the ass.

Do you need to have tires or anything else off to install the brackets? I may do the springs and sway bar links first and then tackle the brackets a week or so after. I just want to make sure I am not doing double work and therefore needing to do everything all at once.

OK. Ordering tomorrow and should have Thursday. Coils within the next week to ten days. Shocks around the same time. I can't thank you enough Ken. It can't be easy answering the same questions over and over for folks like me who are wet behind the ears. Me and my JK owe you a great debt of gratitude.

I put a 2.5" Teraflex budget boost on my 2013 2 dr and it drove like crap, all over the road. I did not check the caster at the time but figured it was off. I installed the AEV brackets due to the actually have adjustment for the 2.5" height. Well now it drives perfect I mean 75 on the highway with 1 finger perfect. My caster now by following Kjeeper10's method of checking it is 4.5.
