Terraflex and RK are good.

RK seems a more complete kit in the x-factor version.

Take a look also at synergy stage 3 lift very interesting kit.

MC Game changer ARB edition is hard to beat and it is the most complete bolt-on kit.

all of those are more off road oriented.

AEV is very good on road and decent off road.

 

I started with the RK 2.5" max travel and really like it. I've since swapped out the springs for 4" Evo. Not because I didn't like the RK springs, but because I was having rubbing issues with 35's and wanted the 4" for 37's (soon).

If I had to do it again, I'd just buy an RK 3.5" lift, or even an Evo Enforcer 4". I've heard of issues with the Teraflex springs starting to sag, so wouldn't go with them.

 

There's too many variables to say which lift is "best"
You'll see a lot of people running a mix of company's parts. Height and components included play a big factor. You can install the softest best riding 4" coils without axle adjustments, decent shocks etc and be hating life.
AEV rides nice mainly because of their drop brackets.... I run Ranchos version and RK coils. Rancho 9000 shocks. Jeep drives well except for riding on E tires.
It all comes down to personal opinion and how the jeep is going to be used.

 

Drop brackets are great for on road, awful for off road.

 

Why do you say they're awful for off road?

 

The drop brackets get caught up on rocks and other things. It's essentially cheating physics to save money. You can always add control arms later if needed. You just want to avoid anything with the drop brackets if intending to wheel it. Probably fine on easy trails. Just would be a problem on medium to hard trails.

 

There's some long arm kits that hand low just as much.

 

Are they AEV long arm kits? Avoid those too.

 

That just sounds wrong lol

 

The drop brackets cannot be caught on rocks because they don't sit lower than the control arms. The drop bracket lower the rear of the front control arm by about 1'' on a 2.5'' lift.
The front of the control arms is still a bit lower with the drop bracket.
So chances are you will hit rocks with both control arms with drop bracket and without. Just the rear of the front control arms is a bit more exposed with the drop bracket.
The advantage with the drop bracket is they will take the hit and they might bend but your chance to break the OEM control arms mount is therefore reduced.
The AEV drop bracket are cheaper to replace than the oem mount.
There is a huge improvement in handling with the drop brackets and I wouldn't ride without them even off-road.
It is not the only trick AEV has, Their triple rate coil spring and specially tuned bilstein shocks are amazing whatever you are heavily loaded or not.
