This JKS Jspec 2.5 inch lift kit is for those of you who have a 2007 and up four-door JK
and are looking for a 2.5 inch lift kit that's very well-built and also very complete.
Now, the J-control version of this lift kit is going to be more expensive.
It's also going to include some additional components like some control arm brackets
to help correct for your pinion and your caster angle in the front of your jeep, where this
kit is not going to have that.
So, can you run 2.5 inches of lift without any sort of caster and pinion correction?
Yes, if you decide you do want to run some sort of pinion or caster correction, you can
always add a set of control arm brackets or get a set of adjustable control arms which
will also add some articulation to your Jeep.
We'll talk a little bit more about that in just a second.
A kit like this that's at 2.5 inches is going to be for those of you who want to run roughly
a 35-inch tire, still have some room to flex.
That's going to be a combination that looks really good, but also works very well on-road
and off-road.
Now, the JKS does provide, like I said before, a very well-built, well-put together lift
kit that does include a set of Fox shocks.
And even though these aren't the top of the top of the line Fox shocks, this is still
going to drive the price of this lift kit up a little bit.
So, when you're looking at JKS, you should expect a well-built, fairly complete kit,
however, you are going to pay a little bit more because of the quality of the components
that are included.
This is going to be a two out of three wrench installation that will take you around three
hours to get done.
We'll talk a little bit more about that in just a second.
This kit includes a set of four new coil springs which are going to provide those 2.5 inches
of lift, and these are going to be a dual rate coil spring.
Now, there's much debate about what is best, a linear, dual rate, triple rate or a progressive
rate spring.
The dual rate that come in this kit are going to provide a fairly comfortable ride when
you're at ride height, but also a slightly stiffer spring when you do get down too close
to a coil bind situation, so they're going to be good for off-road as well as on-road.
As I said, this does come with a set of Fox shocks for that new taller ride height.
These are going to be the Fox Adventure Series 2.0 shocks.
Now, these aren't going to be the T6061 aluminum that the higher end Fox shocks are.
These are going to be an alloy that are covered in a powdered coat finish instead of just
a clear anodized finish, but either way, they're still going to provide a really nice ride.
These are going to be a nitrogen-charged shock, and the nitrogen-charged inline shock is there
to eliminate any sort of bubbling or cavitation that you can get in the shock fluid when you
work that shock really hard over time.
Working a shock over a long period of time or hitting some higher speed washboards can
cause some shock fade, and the nitro shock will have a lot less of that, help to eliminate
any kind of shock fade.
Now, in general, a nitro shock will ride harder than a hydro shock, but most of the ride quality
does come down to valving, and that's something that Fox does really well.
So you're still going to be in a comfortable ride from these shocks while still getting
the benefits of that nitrogen charge.
Here, you have a front track bar that comes in this lift kit.
This is going to be an adjustable track bar that's much stronger than the factory bar.
The factory track bar can start to flex when you get a larger tire on your Jeep.
This is going to give you zero flex so you're not going to have any wobble-type feeling.
And this is, of course, adjustable, so you can fully center that front axle underneath
the Jeep.
Over here, you're going to have a rear track bar bracket.
This doesn't provide you with quite as much adjustability as some of the other ones out
there.
You're not going to be able to change the roll center.
It doesn't give you three different positions for mounting your track bar.
However, it is a very well-built, very stout track bar that's going to get the job done,
moving the mounting point up a little bit, flattening out the track bar angle and working
very well to get you back on the road again.
Over here, you have a set of JKS Quicker Disconnects for the front of your JK after you get the
lift installed, and I really like these sway bar disconnects.
These are going to be adjustable so you can get the length exactly where you want it,
and you can disconnect these from not just one side, but both sides, allowing you to
completely remove them and throw them in the Jeep as opposed to some of the others that
just allow you to disconnect from one side and then fold them up out of the way.
These are also going to be greasable.
They fit very tight so you're not going to get any rattles, and because they are greasable
and made of high quality materials, they're going to last you a good, long time.
The kit is also going to include all the hardware necessary to get it installed, as well as
some brake line relocation brackets that are going to be necessary to ensure you don't
pull the brake line taut when you're off-road.
This is a $1,200 lift kit and a lot of that cost does come from the Fox shocks.
Fox does make a premium product.
They do charge a little bit more for them.
And even though these aren't Fox's top of the line shocks, they are going to be more
expensive than some of the other kits out there that have a more no-name style shock
with them.
But, you're not just paying for the shocks with this, you are getting a lot of components
and you're getting a lot of high quality components from JKS which are going to make this lift
kit ride really well and last a long time.
So, in my opinion, this is worth the $1,200 price tag.
This is going to be a two out of three wrench installation that will take you around three
hours to get done.
This isn't a kit that includes control arm so you're not going to have to do that additional
work, which will cut down on the time a little bit.
You're going to want to have a socket set and some wrenches handy, of course, some jack
and some jack stands.
If you have access to a lift in either pneumatic tools or electric tools, it will definitely
speed the process along, and I always recommend to bring all of the applicable nuts and bolts
with a good penetrating oil well before you get started.
That time spent is going to pay dividends in the end, speeding up your installation.
Now that we've got the Jeep in the air, we're going to remove the wheels.
We're going to start off by supporting the rear axle with a pole jack.
Then we're going to move on to removing the shocks, the track bar, the springs, and the
sway bar end links.
Using an 18-millimeter socket and wrench, we can remove our lower shock bolt.
Using a 16-millimeter socket and a long extension, we can unbolt the upper shock mount bolts.
Next, we're going to remove the lower sway bar link bolts using an 18-millimeter socket
and wrench.
Next, we're going to remove the lower track bar bolt.
Next, we're going to remove the E-brake bracket.
And I'm going to let this hang.
Next, we'll use a 10 millimeter and remove the brake line bracket.
Next, we can lower our pole jacks down to lower the rear and remove the stock springs.
So, first step for the rear installation is we're going to bolt our bump stop extenders
to the rear, using the blocks provided and the provided hardware pack.
Using two 13-millimeter wrenches, we can tighten these up.
Next, we need to drill some new holes for our lower sway bar end links, to accommodate
the new lift.
So, we need to measure up an inch-and-a-quarter from the center of the factory hole.
Make a mark, and we need to drill a half-inch hole.
Next, we can mount our track bar relocation bracket.
And this spacer about through here.
We're going to use the factory bolt and nut tab for the bottom portion of the track bar
bracket.
Next, we can bolt up the support bracket.
And now we can loosely install our E-bolt.
We can go back and tighten everything up now.
Next, we're going to tighten up the two E-bolt nuts with the 19 millimeter socket.
And you want to do this evenly, so don't tighten one side all up at once.
Do a little bit on one side and swap to the other side.
Now that we have our track bar bracket installed, we can begin by putting our shocks in.
And then we'll move on to the springs and we're going to attach our sway bar end links,
and put our brake line drop brackets in.
Next we're going to install our new springs and we're going to reuse the factory spring
isolator for the top.
Next, we can reconnect our sway bar end links.
Next, we're going to install the rear brake line drop brackets.
We use the factory hardware for the upper bolt.
We're going to use the supplied hardware for the bottom hole.
The top bolt's a 10 millimeter, bottom bolt is an 11 millimeter.
Next, we're going to start off by removing the lower shock bolts using an 18-millimeter
socket and wrench.
Next, we can move on to removing the sway bar end links, 18-millimeter socket and wrench.
Next, we can remove the lower track bar bolt.
And remove the upper track bar bolt next, and completely remove the front track bar.
Next, we can remove our brake line bracket to make room for the brake line bracket extender.
Next, we can lower the front diff a little bit, and we can pull our springs out.
Next, using a 16-millimeter ratchet wrench, we're going to disassemble the top portion
of the shock.
Next, we need to drill a hole in our spring perch so we can add a bump stop extension.
I'm going to install the spring with the bump stop spacer loose.
It will be less distance.
I have to compress the spring and make it easier for installation.
And once we get the spring in, then we can bolt our bump stop spacer in place.
Next up, we're going to be installing our new Fox shocks.
Using a 19-millimeter wrench, we're going to tighten up the top shock now.
Next, we're going to install our front brake line and drop brackets.
Next, we're going to install our Quick Disconnect sway bar end links.
Be sure to tighten the jam nut.
We can now reattach our lower shock bolts.
Last but not least, we're going to install our front track bar.
We can get our pole jacks out of here, and we've successfully installed the JKS lift
kit.
Make sure to get your vehicle aligned, and after 500 miles of driving, double check all
your bolts that were previously loosened.
So, if you're looking for a high quality 2.5 inch lift kit, I definitely recommend the
JKS Jspec 2.5 inch that you can find right here at extremeterrain.com.
