clearly. and, that is something that interests me. after having signed up to be a member over 4 years ago, why do you now have a sudden interest in posting on this particular topic, of which you claim to be very familiar with and, have made ALL your first posts on? i'm also very interested in why you keep on doing searches for "aev" and reading through hot topic threads regarding them.



please do tell how you are able to provide this "unbiased, real world information". please do tell me about all the apples to apples experience you have with various lift kits made specifically for the Jeep JK Wrangler.
Hmmm, where to begin....

How about this fact: I have NEVER used the search feature on this forum, ever.

Stress on shocks and spring is not an issue and I never suggested it was. However, the brackets lower front control arm angles, and more level arms, especially lower arms, mean a better ride. That is simple physics.

Your opinion of AEV's bracets is just that, one opinion of many.

Yes, among other benefits like significantly reducing brake dive, reversing pinion angle rotation vs. oem or adjustable arm set up allowing the retention of the vibration free oem Rzeppa CV's, AEV's brackets reduce body roll/lean in turns. And rather than me writing a long, full and detailed explanation of how, that it seems you wouldn't believe anyway, I'll refer you to the book "Fundamentals of Vehicle Dynamics" by Thomas D. Gillespie and offered for sale by the Society of Automotve Engineers on their website.

I have read, with interest, different threads on different topics while I have been a member, sometimes logged in, mostly not. I have paid particular attention to tire and DS threads, and threads regarding transfer case issues. But why is what I read or choose to post about significant to you? Why are you so fearful of an open exchange of opinions? Get a grip man, we're discussing the pros and cons of a set of $100 brackets.

My real world opinion is based on a wide range of sources, but including experience riding and driving rigs with AEV and other suspensions. I have experience with prior Wrangler and CJ Jeeps too, but as we all know, or ought to, the JK's are different beasts. Real world opinion based on the knowledge that too many guys build their Jeeps for chanllenges they will never see, and pay, every day, the penalty for that last degree of articulation needed or utilized, or maybe that last degree of skid protection, i.e. weight never required, or pay for that grenaded transfer case caused by a double cardan shaft and the inevitable trade off between too little caster angle or too much pinion angle. The lack of bias comes because I fully recognize and write about the cons of AEV's brackets as well as the benefits.

As for some of your other comments about AEV suspensions, if you price the others, say Rock Krawler for example, and add the pieces missing - shocks come to mind, the AEV pricing is pretty similar. That is true of the realm of competing, quality bolt on short arm suspensions. With AEV, $1,650 and a long day of installation or the bill from the shop for installation and you are done. Nothing is adjustable, nothing needs to be.

On the bracket count, compare suspensions, the RK and AEV have exactly the same number of brackets, except AEV's suspension includes the control arm brackets. This is the same for most all other quality alternatives. In fact, if a kit is missing a bracket then it is incomplete and fails to address geometry correction that needs, or at least ought to be made.

Get a grip man and lighten up, were discussing $100 brackets. No call for the venom, the name calling or the ad hominem attack.

funny, whenever i looked at your profile, you were only reading through hot topic aev threads like this:

https://www.jk-forum.com/forums/show...8-AEV-3.5-lift

being that threads like it were quite a few pages back, i could only assume that you found it doing a search.

also, you still haven't answered my question as to how you are able to provide "unbiased, real world information". please do tell me about all the apples to apples experience you have with various lift kits made specifically for the Jeep JK Wrangler. i'd also like you to explain exactly how these drop brackets "help reduce body roll/lean".

cat got your tongue? here's a little help from aev's website:

AEV's Front Control Arm Drop Brackets pack a lot of suspension performance improvements into a small and affordable package. These drop brackets will improve front impact ride quality (expansion joints, ledges), increase anti-dive for improved braking performance, decrease the operating angle range of the front driveshaft, and eliminate the need for adjustable control arms or cam bolts for caster correction.

Improve front impact ride quality (expansion joints, ledges) – By reducing the operating angle of the front control arms, the suspension is allowed to work in a more natural state. This means that when hitting a bump, the force applied to the control arms is directed up into the springs instead of back directly into the frame. In effect an AEV 3.5” lifted JK “thinks” its lifted only 1.25”.

Change the instant center to increase Anti-Dive for improved braking performance – By increasing the anti-dive geometry of the suspension, you’ll notice the front of the vehicle will barely drop under hard braking when the control arm brackets are used. By increasing force on the front wheels, traction is increased for better straight line braking and by reducing the shifting weight and inertia under braking in curves, handling is greatly improved.

Decrease the operating angle range of the front driveshaft – This one is often overlooked. Aftermarket double cardan joints do not have the torque rating (1850lb/ft for t a 1310 double cardan, 2150 lb/ft for the OE CV Joint) and they can’t run as smoothly so its advantageous for most JK use to keep the stock CV units. The Front Control Arm Brackets rotate the pinion up as the axle drops to eliminate torn boots on the CV for long life with a lifted application.

Eliminate the need for adjustable control arms or cam bolts for caster correction - We’ve been touting the benefits of using the stock control arms for a long time because of the pre-loaded rubber OE Bushings that the factory uses, and because that quality has yet to be rivaled in any aftermarket bushing. These new brackets allow for the proper caster ranges to be achieved.

AEV Front Control Arm Drop Brackets are included in all AEV 3.5"/4.5" DualSport suspensions, but can also be added to AEV's 2.5" DualSport suspension as well as other manufacturer's suspensions. See Tech Specs for more details.

Key Features:
• Improve front impact ride quality
• Increase anti-dive for improved braking
• Eliminates the need for adjustable control arms or cam bolts
hmmm, nope, don't see a single thing about how these brackets "help reduce body roll/lean". but, that would be par for the course when it comes to fanboys - they always do a lot of talking about how wonderful the parts they buy are without actually knowing what it all means

being an avid drop bracket basher myself (I've wheeled poorly enough to already have to replace my crossmember and front axle at 9k miles), I always tell people "i've been wheeling less than a dozen times. my control arm brackets are smashed in, my gas tank skid blown away, my evap canister destroyed, and my cross member looks like its literally been beating with a sledge hammer. why would you want to make anything on your jeep hang lower!". That being said, people seem to always rave about AEV lifts; I actually like hearing about peoples experiences with them. However, I continue to look forward to reading about someone doing some wheeling with them, and getting their feedback and post run pictures. It seems everytime someone mentions "I use the AEV brackets" they immediately follow it with "and my jeeps most extreme ride was down a gravel road with a few pot holes". Has anyone actually wheeled with these things? If so, please, tell us about it!

Im starting to love these AEV bracket threads!

Great way to laugh away a lunch break, listening to how brackets do more than actual components for a suspension system.

Great job AEV, brackets like crack. I love it

For the record, I have no dog in this fight. The only AEV product I own is their jack base. I like AEV well enough, but I recognize that Eddie's criticism is well-founded. That's all I'll say about that.

But, I do take issue with your claim that someone who isn't breaking axles isn't wheeling their Jeep hard enough. I've been over 1,000 miles off-road over the past couple of years, including Texas, Utah, and Arizona. None of it was "extreme" four-wheeling, although I've certainly run some challenging trails. I take more of an overlanding approach to wheeling. This includes spending multiple days on-trail and doing a bunch of primitive camping.

Does this make me less of a four-wheeler than you? Does it mean that if I buy an AEV lift and it works for my purposes, that AEV's product isn't a good one just because I don't beat the hell out of my rigs?

i'm sorry but, i fail to see how anyone has been prevented from being heard or have their rights to offer advice or perspecitive restricted. if anything, it would seem that you think that my voice and my ability to give advice and perspective should be restricted.
Nothin but respect my brother.

For the record I am not an AEV fan boy. I own nothing that comes from AEV. And I believe your advice and reasoning is well founded and completely accurate. I would much rather have EVO coil overs and long arms than anything from AEV or any other vendor. I can't wait to see the new EVO bolt in coil overs for example that you are featuring on another thread. I never meant to imply that you were trying to restrict anybody's point of view, and I would never ask you or anyone not to express your own point of view, just the opposite. I guess it's the "playing" with the AEV fan boys, as you put it that is rubbing me the wrong way. The general tone of the discussion does not sit well with me. It kind of feels like the cool kids picking on the uncool kids on the playground. I don't mean to preach or judge or what not. Sorry if it sounds that way. I was just trying to stand up for the uncool kid. If you all want to beat me up or bash on me too I guess that's your choice.

Again, nothing but respect for you personally and for the great venue you have created.

I wont lie, most of the damage I'm sure is from poor offroad form on my part. But the point still stands, why would you want anything to hang lower? I know I'm not the only person who trashes the underside of their jeep, its part of offroading. thats why you skid everything, and lift up the body, to try to get things out of harms way

at picking on the "uncool kids" - i love it!!

the tall and short of is, i have a real problem with bad information especially when it's told with authority and really, nobody is worse at spreading bad information than fanboys. they're quick to be sold on good marketing and eager to regurgitate what they've been sold without actually understanding anything or having any experience with anything else. if fanboys want to come on here to shoot off their mouths like they somehow know what they're talking about, i say bring it. just know that there are mean ol' guys like me watching and, while you might call what i do "picking on" them, i call it challenging them. and, of all people, i think you know full well that if i can be proven wrong, i would be the first to admit it.
