Rock Krawler Vs AEV

Guys I need some help deciding as I have been doing non stop research and asking millions of questions to more experienced members of this forum.

Basically I have my lift narrowed down to two Kits. One is cheaper and comes with less hardware and one is more expensive but comes with all the hardware i would need to get regardless.

First Lift- Rock Krawler 2.5 inch Stock Mod kit.

Cheapest I have seen online- $519.00 including shipping.

Heres a link.

Rock Krawler Suspension RKJK25SM - Rock Krawler Stock Mod 2.5" System for 07-13 Jeep® Wrangler & Wrangler Unlimited JK - Quadratec

Now with this kit there are no shocks included and either way im getting the Bilstein 5100s-$80.00 multiplied by 4 comes out to be $320.00

Total price for this kit: $839.00 with everything BUT- this does not include the bumbstops and other small parts i feel would be nice to have.

Second Lift- AEV JK DUALSPORT XT SUSPENSION 2.5 Inch.

Now with this kit it has everything i would need to lift including some extra hardware I feel i would get regardless. The AEV comes with the Bilstein 5100s included.

Heres a link.

JK DualSport XT Suspension 2.5" - Suspension - Shop By Category

Total price for this lift with everything-$899.99

Thoughts and opinions would be great. The price difference is only $50.00. I have read almost all review threads regarding these two lifts. Im not looking for reviews im looking to see which you would choose when comparing hardware in both of these kits.

I have seen a lot of people say that RK rides and is better quality? OH and one more question i have been searching for-do these kits get rid of the factory rake?

Thanks guys!

Haha this will get interesting.

AEV is more geared to overland. Great on the street and not really geared towards rock crawling.
RK- Don't let the name fool you. RK is fantastic on and off road. I love my RK coil upgrade.

AEV gets a bad name from the lack of adjustability and some of the brackets used.
Both great lifts. It's really up to you.

If you do go with RK stock mod. I would also include some LCA's. since you have a 2 door and RK coils will give you more than 2.5. You might experience some flighty steering at highway speeds. LCA's and caster adjustment will fix that.
Or go the next step up in the Max travel.


Good luck

I missed your other thread.

I got almost if not 4" from the RK coils on my 2 door. Front DS was going and rear is not to far behind it. I have upper rear control arms but been to lazy and have not installed yet.

^^^ Good info here.

It really depends on what you're gonna do with your Jeep. If the lift is more for looks, I'd go with the AEV.

If you plan on doing a good bit of wheeling, and think you might do more than just fire roads, beaches, etc, I'd buy the RK – with the additions kjeeper mentioned.

Personally, I'd go straight to the Max Travel version of the RK, too. But you've gotta decide if that's what best fits your needs.

This is exactly what I am worried about with the RK. Believe me I plan on doing some off roading on barely ridden trails but nothing crazy like rock crawling. I don't want anything over a 2.5 inch lift because i don't wanna spend another $1,000 on a new front end and driveshafts.

Believe me I would love to go with the Max Travel setup but i just cant get by spending $1,400 on a lift kits
RK is completely easier to upgrade as i get more money as there lifts all use generally the same parts but I'm still worried about there 2.5inch lift becoming a 4 inch lift.

Basically they are the same price but the AEV comes with bumpstops and misc. aids which i don't have to go and search for.

Are you including the geometry correction brackets in the cost of the AEV kit? Those are an extra $100. If I went with AEV, I would get the brackets.

in terms of "kits" niether of these really fall into a "whats better" setup. the AEV in this case will actually be nicer, because the RK kit only springs, a front track bar, and a pretty weak looking rear trackbar bracket. their directions say specifically that unless you weld it on, not to do any wheeling with it. on top of that, youre on your own for shocks, and brake lines. If you go RK, go with an actual kit, screw the stock, go for the 2.5 or really, go 2.5max. easily one of the best kits on the market (also, in terms of price, DO NOT BUY OFF A WEBSITE websites will all list the msrp. hit up some vendors. jason at krawloffroad always has a good deal, and I usually check with marcus at rivercityoffroad, or with bryan at 4wd. these guys love RK, and have no issues slashing 10-20% off the listed price.

I will always say RK over AEV, but between these two setups, AEV hands down. 2.5" doesnt really need much special to make it work, but if you do just springs, you'll want to recenter your axles, and you might not be happy with the highway handling.

Interesting stuff you brought up,

Im incredibly new with this whole process-

recenter axles? can you elaborate a bit more? Not sure what you mean by this.

They (AEV) really should add the geo correction brackets to the basic kit for one combined price. The kit is incomplete without them, and you'd have to be crazy to run it without them. It's kinda silly that they sell them separately just to pretend the price of the kit is lower than it actually is...

I mean don't get me wrong i plan on doing off roading and having a blast but I also am not going to be going extreme and flexing on rocks or hills that are 4 feet off the ground.

I spend quite a bit of time on the rocks in Moab and Colorado and consequently chose the AEV. If you spend significant time offroad buy the AEV. I'm shocked it is in the price range of the other brand, you are fortunate. Buy the $100 front lower control arm correction brackets without regard to which brand of lift you get. They are certainly not specific to the AEV lifts and the handling improvement is significant.

In my mind, the actual price of the AEV 2.5" Dualsport kit is $1150 (kit + geo brackets + ProCal).

I've been talking to my dealer about getting it installed on my '13 when it arrives, but they want $2450 to do the above parts + brake lines. Their pitch is that they're willing to give me the 3/36 warranty on the lift install as well (in writing). I'm not really sure that the high price is worth it, though...?

I'm leaning toward grabbing the RK 2.5" MaxTravel + Fox 2.0 shocks, and then just learning how to install it myself (with a ton of help from my local Jeep club!).

All brands of lift kits are incomplete without these AEV brackets. There is nothing specific to AEV that requires these brackets.

I have never heard of anyone installing AEV's geo correction brackets on a non-AEV kit. Are you suggesting that they're necessary for proper alignment on kits like the RK MaxTravel as well?

That's really the first I've heard that, but I'm here to learn!

My friend did with 2.5 budget boost and 18 front springs. Helped a lot.

You want a front track bar to center the axle.
A good rear TB bracket is really to correct geometry/roll center but does help with axle center.

If im not mistaken a front track car comes with both of these kits?

Im not following on how to "center the axle" though. that part im lost on.

With a BB, that makes some sense. However, Silverton said that "NO kit is complete" without the AEV geo brackets -- which is the first time I've ever seen/heard someone claim that no kit on the market is complete without them.

I've honestly never heard of anyone with the more complete TF, OME, or RK kits (2.5" or larger) using the AEV geo brackets to address geometry issues... have you?

Mind you, I'm new to most of this, so I could be wrong. It's simply my understanding that more complete kits (like the RK MaxTravel) use adjustable control arms and trackbars to accomplish the same (or similar) geo corrections -- thus making something like AEV's brackets unnecessary.

Once again, I could most definitely be wrong, so I'm just very curious about this.

Stop. Your dealer has no authority to amend or extend chrysler's warranty coverage, which only covers your jeep as it left the factory. What's changed isn't covered and what's damaged by what's changed isn't covered.

So you will NOT have Chrysler warranty coverage on that lift. The dealer--not Chrysler--will be providing that warranty, just as local 4x4 shops should warranty their own installs.

Call some local shops and get competing prices. You get no warranty benefit from a dealer install, so they should either compete on price or GTFO.

There's nothing magic about AEV's 2.5" of added height that makes geometry correction something that only an AEV lift would benefit from.

When you raise your frame farther from your axles (whether through an AEV lift or some other brand), you lose camber, resulting in flighty handling. The typical correction for this is longer lower control arms (LCAs), whether they're fixed or adjustable. AEV has come out with brackets that accomplish this as well--they essentially make your stock LCAs longer.

In general, 2.5" of lift isn't enough to really "need" longer LCAs, especially on a 4 door. By contrast, 3.5" or 4" of lift would make the jeep almost dangerous to drive on the highway without fixing the camber somehow.

You do lose some camber with 2.5" of lift, but it's just not that big of a deal. I have a 2.5" TeraFlex lift and the jeep is a little flightier than it was stock, but not a big deal. Still, I'm debating whether to add AEV's brackets or just go all out and get some good adjustable LCAs.

Trackbars and LCAs do very different things, but otherwise you're right--if you've already put adjustable LCAs on your jeep, you have absolutely no need for the AEV brackets.

When you lift the front axle gets pulled to the drivers side by the track bar.
The rear to the passenger side. Centering the front axle is more important because the steering is involved.
The rear roll center correction is more of a handling thing. This sets the track bar parallel with the axle. Centering the rear is not as important. The bracket does help but not perfectly. For a smaller lift I would not worry.

So you will NOT have Chrysler warranty coverage on that lift. The dealer--not Chrysler--will be providing that warranty, just as local 4x4 shops should warranty their own installs.

Call some local shops and get competing prices. You get no warranty benefit from a dealer install, so they should either compete on price or GTFO.

There's nothing magic about AEV's 2.5" of added height that makes geometry correction something that only an AEV lift would benefit from.

When you raise your frame farther from your axles (whether through an AEV lift or some other brand), you lose camber, resulting in flighty handling. The typical correction for this is longer lower control arms (LCAs), whether they're fixed or adjustable. AEV has come out with brackets that accomplish this as well--they essentially make your stock LCAs longer.

In general, 2.5" of lift isn't enough to really "need" longer LCAs, especially on a 4 door. By contrast, 3.5" or 4" of lift would make the jeep almost dangerous to drive on the highway without fixing the camber somehow.

You do lose some camber with 2.5" of lift, but it's just not that big of a deal. I have a 2.5" TeraFlex lift and the jeep is a little flightier than it was stock, but not a big deal. Still, I'm debating whether to add AEV's brackets or just go all out and get some good adjustable LCAs.

Trackbars and LCAs do very different things, but otherwise you're right--if you've already put adjustable LCAs on your jeep, you have absolutely no need for the AEV brackets.

AEV's brackets also set both CA's at a better angle which directs road harshness up to the spring and shock rather than the frame. Basically smooths out the ride.
Also keeps the pinion pointed up during articulation which saves the DS.

I prefer the adjustability of arms. Will eventually get front uppers to dial in my front as best as possible.

I've honestly never heard of anyone with the more complete TF, OME, or RK kits (2.5" or larger) using the AEV geo brackets to address geometry issues... have you?
never take one persons word as final. my wife does that all the time, drives me crazy. she threw a code on her miata, the rear o2 sensor had fried. so she tells em she researched it, and that if she drives her call shell destroy it!

I thought this sounded wierd, so I did a quick google search myself. checking on the forums, there were about 40 threads covering this very issue. in one thread, one man posted saying that there would be damage from driving the car without replacing the sensor. the other couple hundred posts said it was okay to drive.

needless to say, she drove her car around while we waited for parts to come in. the mob is usually right
