So you don't believe in long arm kits? Oh wait...you have one. Think about it. If you use these AEV brackets, your are lowering the upper control arm mount to a position that flattens the front lowers.....almost exactly the same as a long arm kit would. (unless you modify your axle and
frame mount locations on a long arm configuration) Furthermore, a long-arm kit protrudes further back to the center of the vehicle where the break-over angle is possibly affected. So if anything, a long arm kit would technically create less clearance than a stock, or AEV bracket configuration, but then you don't benefit from the flattened geometry. I don't want to get in an argument over long arm kits being a great solution, because they are....I'm just making the argument that the AEV brackets don't interfere from a clearance standpoint anymore than other long arm systems that are marketed as "extreme off road solutions".
As for the benefits of using the brackets....I'm not saying that these are a fix-all, or the only way to do it right, but they do help on road dampening by flattening the front arms. They also correct for caster on 3" and 4" setups (this is not fine tuned like adjustable arms, but the caster is adjusted pretty close with these). They also help the anti-dive, much like a long arm kit. As far as functional modifications go, these are pretty damn solid for $99, and I'm not a person that goes cheap on my mods. I have wheeled them pretty aggressively, and have yet to have even a scratch on them....so I don't think clearance is an issue by any means.
I still have adjustable control arms so that I can fine-tune my caster....and by the way, I have the JKS. I really do like RockKrawlers products, but I wanted to benefit from the road dampening of a stock-like bushing, yet maintain the flex feature that JKS offers. I feel like this is the best option for me, granted not for everyone. My main goal was to build a very capable off-roader, but maintain the best on-road mannerisms possible because I drive my jeep to the trailhead, and around town, and on road trips etc.
As for the debate of the stock bushings not being durable....I believe that they are the most durable option. A fully bonded bushing can fail, and I know they do, but there is a reason that manufacturers use these bushings, and test them to a benchmark of 100,000 miles. I have used JJ's before, and the ride has been a bit more harsh, and the joints seem to loosen up and fail within a short period of time. If you are willing to do the labor and continually maintain/rebuild joints, and are serious about off-road performance only, then I suggest any quality adjustable control arm with JJ's. If you want more of a maintenance free setup, use the the stock arms with AEV brackets, or JKS style arms that utilize fully bonded rubber bushings (much different than the polymer synthetic aftermarket bushings)
