Any drive train or other geometry issues that need to be corrected with parts not included with the 3.5 jspec lift kit?

MarkB

  • With the JKS Jspec 3.5 in. JKontrol Lift Kit the only additional parts that JKS recommends are a steering stabilizer and exhaust spacers. The spacers are for 3.6L model Jeeps only. Every Jeep reacts differently to being lifted and you may find that at 3.5" your stock driveshafts are overextended and you need to go to aftermarket ones rated for your lift height.

If I replace the driveshafts with longer ones do I still need the exhaust spacers? In some kits it looks like a new driveshaft resolves the problem and doesn’t require the spacers for the exhaust.

DanielS

  • If you have this kit JKS Jspec 3.5 in. JKontrol Lift Kit and decided to replace the driveshafts with longer shafts, you would not need the exhaust spacer.

I bought extended break line thats accomodate 3 to 4 inch lifts. Will that be enough length for when I remove my swaybar disconnects?

VCadi

  • Yes, those extended brake lines should be perfect with your JKS Jspec 3.5 in. JKontrol Lift Kit!

Hi. I'm thinking about getting this lift kit. What offset do you recommend on 17" rims with this kit?

JohnE

  • Thank you for your question! Any wheels will fit with this kit since the life does not effect the wheels. The offset and backspacing of a wheel would have to be at 4.5" of backspacing or less for some steering components and tires.

have any of you had to add a drive shaft to this? I am seriously looking at getting this kit to run 35 tires and to do some off roading but nothing major

JoelA

  • The JKS Jspec 3.5 in. JKontrol Lift Kit will require a driveshaft to ensure proper clearance through the full articulation of the suspension.

Will I need any other parts for this to fit my 2011 Wrangler unlimited sport? And is the stock driveshaft ok to use with this lift or is it recommended to buy a larger one?

TaylorK

  • With the JKS Jspec 3.5 in. JKontrol Lift Kit (07-17 Wrangler JK 4-Door) you can use your stock driveshaft, just be sure to add an exhaust spacer like this https://www.extremeterrain.com/jks-exhaust-extension-kit-8150.html. If you are going to be hitting the trails often, I would recommend upgrading the driveshaft to a longer one.

    Jkontrol = Awesome

    Just reiterating on what everyone said, this is a solid product. Here's a quick review of the parts and install. Pros: -excellent fit and finish. -materials used were super beefy and solid. -hardware (nuts and bolts) are all individually package for ease of installation. -best colored instruction manual I've used. Not some cheap piece of paper that'll ripp halfway thru the build. -comes with Fox 2.0 shock:) *after a few days of driving on Highway and small offroad obstacles, this kit is amazing. After getting alignment, everything was in spec, including caster. Cons: -I'm not a fan of drilling so I purchased a set of jks adjustable rear endlinks. Also wished they included exhaust brackets. -Had to drill to do the flip drag link mod. Wished there was another way. -they could have put more details on installing and adjusting the steering and trackbar. Make sure you do additional research. *the adapter brackets for track bars are a tight fit, especially the front ones. Just take your time and to get those holes lined up. Conclusion: It really is a good lift kit with quality parts. It's not an easy installation but doable. I'd hate to say it, but it really does ride better than stock.

    Review from JKS Jspec 3.5 in. JKontrol Lift Kit (07-18 Wrangler JK 2 Door)

    Pretty good......but......

    JKS products are top notch. Here's a couple of things to note if you intend on buying this lift. 1. You don't get new rear sway bar links. JKS has you drill holes above the old link holes on the axle.----$80 for JKS adjustable sway bar links on ET. 2. Buy some coil wedges for the rear---$30, trust me. 3. I had a heck of a time trying to get the rear track bar into the rear track bar bracket. I decided the heck with the bracket and bought an adjustable track bar---$130. 4. You'll never get your front axle centered by yourself with the jam nut style front track bar. Get it close, take it to get an alignment shop, and let them deal with it. ------ All in all, I dig it.

    Review from JKS Jspec 3.5 in. JKontrol Lift Kit (07-18 Wrangler JK 2 Door)

    Nice Lift for my 2012 JK

    Put the 3.5 JKontrol lift on with 33in tires on 18 rims. Looks great and rides about the same as stock. I would say it's close to stock but the ride is better.

    Highly Recommended

    Intalled simultaneously with 17in wheels and 35in tires. First impression on and off road is that it feels very much like stock... but better. Yes with the 35s I slapped on, it is a little more sluggish. However, steering feels much better, the Jeep doesn't rock as much as it did when it was stock. Before, it felt like a bobble head on a boat whenever I would turn or hit bumps. Now, the suspension is much stiffer so it does provide more stability while driving on and off road. I do recommend a few separate things to buy if you are thinking about this kit: 1. Exhaust extension kit. You WILL need an extension kit for your exhaust to protect your drive shaft especially with a 3.5 or higher lift. Many will say that you won't need it. But wait until you are at full flex and realize that your boot is messed up. 2. Adjustable control arms. The brackets provided are cool to look at, but lets face it the stock control arms are ugly. Not only that, the brackets kind of take away some of the clearance that you would otherwise have without it. Maximize the clearance you would get from this kit and buy adjustable control arms. 3. Extended break lines. I'm not a huge fan of the break line relocation brackets that come with the kit. However, they will do the job. I am currently waiting for my extended break lines to arrive so I can replace the OE break lines. 4 out of 5 stars only because of the 3 things I mentioned. Otherwise, very good looking, very good quality, and seems like a very sturdy product. I think I was meant for those of us who intend to slowly build our Jeeps rather than for those who like to spend an arm and a leg for a very complete kit. I am a very satisfied customer and I highly recommend the JKS JSpec 3.5in JKontrol lift kit.

    Smooth On and Off-Road

    I installed this lift a few weeks ago and I could not be happier. It rides smoother than factory and it looks awesome! I highly recommend this lift kit!! I do suggest buying the JKS rear sway links. I installed them while installing the lift, so there was no need to drill the rear tabs. Easy to follow instructions. Definitely worth the $$$!

    My first lift

    From stock to these---WHAT A DIFFERENCE!!! The ride quality on road is great. I didnt give a good review on thr off road due to not having taken it out yet. Installation for a first timer is hard. You NEED an extra set of hands. We messed up a few times and had to uninstall backwards to get it to fit right the 2nd time. The instructions are very bad at some areas, hens the uninstallation and reinstallation of certain areas. Atthe end though, im VERY pleased. Hint, my steering was off 90•. Thats because we didnt set the steering wheel center before installing the steering rod.

    Pay for what you get.....

    Went with the 3.5" JKS lift and debated between this lift and AEV as I was looking for strong on road behavior and the ability to have some fun on weekends all while running 35" tires. Installer even commented that it was a well built kit and enabled stock specs for a safe and confident on road/highway ride for mom and the family. Very happy after 2 weeks so far and no issues or rubbing.

    Top of the line lift kit

    The instructions of the lift kit could be improved as well as including the step drill that they claim to include. Additionally the hardware included in the kit could've been organized better. Regardless I'd highly recommend this kit, each piece is so solid, I have zero concerns while wheeling. Everything except the front track bar bracket lined up like stock.
