Wanted to give some final reviews/impressions on the JKS JSpec kit that has been a pleasure all the way from the beginning.

I first ordered the kit from Ryan at XtremeTerrain. Packaging of the parts were top notch, and instructions were very clear. You can also print out different instructions specific to each of the parts from JKS website directly to get more in depth instructions.

The lift kit went on without any issues, with the hardest part being the installation of the bumpstops in the front. You really need nice new sharp drill bits to get through those spring perches effectively. Do Not try to skip any drill bits and step them up using 4-5 sizes as not to jump up in size too fast.

Everyone who installs 2.5+ lifts eventually get an adjustable track bar, and one of the most popular one is the JKS Front Adjustable Track Bar. Forum members also highly praise the JKS front sway link disconnect system, touting that it is the best of all. It is this type of quality that make up this kit. By no means, am I being sponsored or paid by the company. Just a very pleased customer!

So onto the details,
When I installed the lift, I opted to install their JKS J-Link Front LCA to correct Caster, although the option to install geometry brackets came to mind. I wanted to stay with JKS, and give them a try despite many people going to Synergy Front LCA.

Today, I finally got an alignment, after about 2 weeks of the suspension settling. Jeep felt good after the lift, even without an alignment, but wanted the peace of mind that everything will work well after an alignment.

I can confirm that with a JSpec 2.5 with their JKS J-Link arms, the alignment was basically NOT needed, IN MY CASE. All Wranglers are different, so keep that in mind. In my case, Front Right Toe had to be adjust only 0.01", only so that the stealership doesn't feel bad taking my $135 for the alignment. Even before they adjusted that, it was within Spec. Maybe that's why they call it a JSpec kit :O Camber is not adjustable on our Jeeps, so don't worry about that.

Finally, while I had the Jeep at the shop, I had them install my JKS Exhaust Spacers/Extensions to clear the driveshaft and exhaust during droop. I looked under and they installed it all well without issues and I can verify that there are no exhaust leaks. The spacers look very nice and are not rough looking like some of the other company spacers. Keep in mind, my Jeep has not been through a winter, so it was a breeze for them. Now, I don't have to fork out for a new driveshaft!

Here are some photos!

Great review.

Next time buy these .. Thank me then lol
I know, from Harbor Freight. Between installing the bumpstops and putting in the springs, the spring perches lose a lot of the paint. I'm going to need to touch up the missing areas one of these days...

Also, that little difference in camber (slightly less negative) and caster (less positive) will probably be PERFECT, once I sit and drive by myself as the driver!

Jeep tracks straight as an arrow, only thing when I am driving 70+ is that the steering feels slightly sloppy on center.

How has the ride been? This is one of the kits on my short list. I drive around 100 miles a day so that is important to me, thanks.

You won't be disappointed once you PM XTRyan and ask for a XtremeTerrain coupon code and use that to order the kit. All the stuff in the kit and you will be barely over what you will spend on TeraFlex 2.5 coil lift with some shocks. JSpec kits comes with their adjustable track bar up front, and their JKS Quicker Disconnects, which people buy separately as well. So, in the end, things are more cost effective buying the JSpec kit...

I've had the same lift since June and I agree with "sined240", very nice kit and it's a pleasure to drive. I never take the short ride home anymore! My wife even prefers to drive it over her new grand cherokee overland, which isn't a good thing......

Your review and pictures, as much as the parts included in such a comprehensive kit with their dual rate springs is what made me choose this kit. Pricing is very competitive for this level too...

Good stuff!!

Did you drill the rear sway bar link mounts or put on a set of links for a 2.5? That is about the only thing I don't care for on the JKS kit.

Did you happen to measure those control arms? It would be nice to add the info to our "database". :beerdrinking:

I ordered the Rough Country 2.5" Rear Links, and moved the rears forward. Now just looking for spring time to install the disconnects that came with the lift. I know if I install that, I want to adjust it just right and fab up a way to hold down the sway bar while its disconnected.

Nice Jeep, the lift looks perfect. What is the clear bra you have listed in your description?
Thanks, the lift has settled a little and looks even better. I was checking out the car while the service was pulling it forward for me, and I am really happy with the way it stands.

The clear bra is a paint protection film that goes on the leading edge of hood, grill and fenders. Seeing how flat our front is and with my painted fenders, it gets a lot of rock chips too fast...

How is the ride right now? Did you also throw on JKS J-Links for the rear or was that not needed?

I'm looking to do a similar setup as it's also packaged with Fox shocks which I love. Thinking about doing the 3.5 thou

It rides great if not better. I have thought about the 3.5 but I am extremely satisfied with the ride without having to spend a ton on steering geometry at this point and having small kids, I will just finish up with the 2.5 with 35" tires.

I only have the J-Link in the lower fronts and have not done anything to the rear of the Jeep as far as control arms.

You will love it, the kits come with Fox Performance or the Performance with the reservoir setup and should ride awesome!
