Installing the AEV 3.5" Lift Kit on a 2013 JK Rubicon Unlimited
Hi All, Hopefully a thread pertaining to this lift hasn't been beat to death. I'm getting ready to install a AEV JK DualSport SC Suspension 3.5" lift kit on my wifes (ah, yeh) 2013 JKU Rubicon 10 Year Anniversary. She uses this vehicle for the time being as her DD so I can only have it non operational over a weekend. Because of this I was wondering if anyone that has installed this kit could give me any recommendations and let me know if you hit any road blocks when installing this kit. I won't have the time to buy/order parts once I start the install. I know at a minimum I have to be ready to:
- Replace the wheels with 4.5" offset wheels or use wheel spacers
- Replace the Exhaust Loop or install the short spacers that move the exhaust back
- Replace the Front Drive Shaft
Any help, advice, lessons learned, etc. concerning this would be very much appreciated. I really have to be prepared to start this on a Friday night and have it out of the garage Sunday night ready for her to drive it to work Monday morning. Thanks
Thanks you guys for getting back on this so quick. I felt the driveshaft could wait until I'm ready to go off road since the main concern is when the suspension drops/droops which wouldn't happen while street driving. I was concerned about the tires hitting something. I heard that on some lifts the tires/wheels hit the end links/stabilizer. I have to still get the exhaust loop or spacers. As far as the spacers go are they reliable and don't look kinda cheapy?
As far as the drinks...they are chillin' (priorities!!)
Thanks Boss, You did hit a tender spot. I hate drilling holes. It seems as if it's a hit or miss with me whether I get the darn pilot hole drilled in the center. My garage is full of tools but I think I need to get them calibrated because they never find the center. It can't be my fault, I'm sure...
The teraflex exhaust spacers didn't provide enough clearance for the stock driveshaft at full droop. With an aftermarket driveshaft it probably would have worked. FYI the exhaust loop isn't the problem, it's the y pipe, where it crosses in front of the trans crossmember. AFE makes a y pipe that will clear any drive shaft, or you can run spacers and an aftermarket shaft. So you get to make that decision.
As stated, be careful drilling the knuckle. If you had time and were really nervous, you could probably just remove the knuckle and take it to a machine shop. Quick work in a drill press or something.
I would advise picking up a synergy or Northridge suspension bolt kit. Replace all of the full length threaded suspension bolts with shouldered bolts. Easy to do while it is all apart, and it saves the trouble (and wear) down the road.
The tie rod adjuster may hang up on the front left sway bar link relocation bracket. In my case I had to hammer the adjuster out of the way so it would just barely clear. Huge safety hazard otherwise that they didn't even mention. Keep an eye out for it.
Be sure to follow the instructions about loosening the control arm bolts and retorquing them after it sits on its own weight.
And, hopefully they've done something to help advise you which bolts go where. The instructions I had kind of sucked. Make sure the coil springs are seated properly. Check and double check the torque, especially on the track bars. Frequently.
I don't remember if aev provided them or if I got them with the synergy bolt kit, but I would get some cam bolt eliminator washers from the front lower control arm axle side mount. The bolts go in a loose square hole, designed to be punched out to adjust caster. It isn't a tight fit, nor a reliable way to set caster on a lifted JK. Get large washers that hold the bolt centered in those holes.
Here is a thread that I made that goes over what I saw during my install. The install of the lift itself took about 8 hours with two of us doing work, plus a lot of testing and making sure things fit right. Which I recommend anyone does when they install the lift to make sure there are no problems in the future. Mine was a 10' so there will be a few minor differences.

Don't forget to get hoses and worm drive clamps to extend your F + R axle breathers. With the lift you might (I did with 4.5 AEV). The stock hoses were way too short!
You can get hoses and plastic couplers at any auto parts store.
Good point. Forgot all about those. I'll have to dig thru my box of hoses and bins of fittings to see what I have and buy what I need. I'm planning on doing the left install next week and it's suppose to rain. I wouldn't be able to take it out of the barn without the hoses on, H2O + Oil = $$$$$$$$$$. It's the little things like that I space out because I'm looking at the major changes.
