The Most Informative Lift Video Made...
Why is this not a sticky?

TeraFlex Tech: Choosing a Lift for your Jeep - YouTube

Cool video. I'm trying to convince the wife that I need a 2.5" lift. Maybe I should show this to her....

PHILDABEAST 06-06-2013 02:46 AM

I had the wife talked into a 3", then I showed her this video and now she wants to go bigger:facepalm:

Great video!

Hockeymonster 06-06-2013 06:17 AM

Excellent. 3" minimum I've always said. And 2 doors are always better crawlers

Not sure why it isn't a sticky, but it is a thread I'm now subscribed to!

jkmohican 06-06-2013 10:32 AM

This is the thread that will end all lift threads.

We all have dreams.

I agree, should be required viewing before posting, "I need help deciding on a lift"

TeraFlex 06-06-2013 10:43 AM

Agreed Dennis did a great job on this video. But if you ever have questions or need some info feel free to ask us or call us and we'd be more than glad to help.

Great video and kudos to teraflex for essentially saying that their two least expensive lifts would best for "most drivers" nice to see a manufacturer not trying to stuff their most expensive products down consumers throats for the sake of sales and profits - but rather putting the day to day needs of their customers first

My teraflex leveling kit is going on today :-)

TeraFlex 06-06-2013 11:06 AM

We really do try to help the customer make the best choice for them. We know that if they drop more than they wanted too because someone talked them into it they will only be angry about the process instead of enjoying their new toys.

hbgirl 06-06-2013 11:16 AM

Great video. Think I've finally decided that the 2.5" spring lift is for me.

fljeepleo 06-06-2013 11:22 AM

Teraflex's videos and customer service is awesome! Maybe we can just send links to the "what lift should I get threads that pop up daily". At least its a starting point for some people.

^^^Agree. Awesome video, helped confirm my intentions on getting a 2.5" spring lift without having to start the dreaded thread :D

As a new Jeeper i would have to say this was the most informative video that ive watched thus far. Thanks a lot!

Researching to make a coil lift on a 2dr safely
Awesome video, thanks for sharing. Here is my understanding of issues that can pop up. My knowledge is just from reading through threads trying to figure out a coil lift that won't break my driveshaft boot. I think i'm right about all of it, but I could be wrong. :whistling:

I would highly suggest checking out this link too by Matador:thumb:

If you're doing a lift it is a good idea to consider changing out some of the stock bolts that come from the factory a bit too small. They can eventually lead to death wobble.

32" is the stock Rubicon KM tire size. Its common forum wisdom that 33" can be run with no lift. Is that with the swaybar disconnected also with no rubbing?:confused: NOTE:With tires you need the proper backspacing from the hub so that you won't rub when turning. That means spacers (badish idea) or new wheels with proper backspacing.
  • 2" Lift = 33" maybe 34" tires
  • 2.5" Lift= 35" tires
  • Over a 2.5" Lift it gets expensive quick for the reasons below.
This link is a good one for a general idea what lift you need

Coil lifts are better because they will give you more flex off road. They are going to be a major change in feel for better or worse. They cost a bit more. They are better if you're going to add a lot of aftermarket steel items/winch.

BB/spacer/coil-puck/leveling lifts will keep your stock feel and give a much more accurate amount of lift, especially with 2DRs close to stock weight. Rough County is supposed to make a good good kit for cheap. For the most part all these type of kits are the same. You can either go stock shock extensions, or go with longer shocks. I wonder if longer shocks gives just a bit more flex? Then they will likely give you a bracket to lower you break line. They will also give you a longer sway bar link to stick on the rear, and the rear will go to the front (2.5" lifts). Rough Country gets recommend for the most cost effective BB.
Break Extension
Rear Shock Extensions
The factory spring stiffness will determine how much they will sag if you add extra weight (bumpers, etc)

Not sure what all parts your are talking about but the coil spring themselves should fit. What you need to do is see if it is worth the switch is check the two vehicles coil spring numbers.

Your springs will have a tag with the stock number on them. The last two digits are letters; Ignore them. Look at the last two numbers. The JK's coils run from numbers 13 to 19 on front and 54 to 60 on rear with the lower the number the weaker the spring.

Example, mine were 14 on front and 56 on rear.

I switched mine out with 19 on front to 60 on rear and got 1 1/4" lift. Many have claimed as much as 2" lift but it has to do with what stock coils they had and the fact I already had extra weight on my Jeep with new bumper/winch and heavy recovery kit in back.

These seem to be only used to correct issues with suspension lifts. As is noted in the video it can be added to solve driveline issues. Its a puck stuck under the body bolts.

Coil lifts will almost, if not always, give you more lift than advertised if you don't have extras like bumpers, a winch, body armor, etc. At 2.5 inches (actual vs advertised) a lift doesn't need much adjustments. As you go higher the expense starts to go up exponentially.

Issue 1) With a larger lift you start needing an adjustable track bar to center the axle (side to side), and adjustable lower control arms to adjust caster. Without longer Lower Control Arms (LCA) you going to give up wheelbase.

Issue 2) On the 2012+ JK's with more than 2.25" of lift the driveline will rub the exhaust cross over. Check out this video
TeraFlex Install: 2012 JK Updated Exhaust Spacer Kit - YouTube
You can add a teraflex exhaust spacer. These will rub slightly on many engine/tranny skids. You can add some washers to shim the issue. With 4drs you can also add an aEf y pipe as a more elegant alternative.

Issue 3) With all JK's you can only lift so far before the factory cv joint on the front driveshaft, at the transfer case side, will be an issue. It has a rubber boot (at the very end not the one in the middle) that will rub at somewhere around 3". I REALLY wish I knew an exact measurement before that rub starts on a 2dr. I think 3" but i'm super iffy and that sucks. After the rub becomes a tear the driveshaft is shot. If that happens a double cardan driveshaft can be added which allows more angularity. I'm going to guess that's around $600+. I don't know at what added height the rear driveshaft becomes an issue:confused:. That also would be nice to know.
This is a picture of the issue. You can see it will rub if the angle is too much.
It's also not great for the front drive shafts cardan u-joint to have too much angularity where it meets the differential (pinion). That will end up speeding up the lifespan on the u-joint.

Issue 4) Teraflex tells you that you need wheel spacers with their 2.5" coil lift I'm assuming that would only be for wider tires and 35s with the stock wheels. I'm not totally sure. There are 2 kinds of rub. One is going to far up, front or back. The other type is created by not having the right backspacing on the wheels which will rub when turning.

Issue 5) Too much lift and awesome becomes roller skates for wheels. To fill out those gaps= bigger tires=tire carrier=regear=less mpg=you broke with a bad ass Jeep.
I'm not sure whos jeep this is. You can just call him "That Guy."

Here is pictures of the LCA's and Body Bolt locations

love these videos :)

Rooster! Great addition to the thread. Cleared up some remaining questions i had.

Rooster76 06-06-2013 04:58 PM

Other things to consider when lifting
I thought of a few more issues to think about when driving around.
  • If your stuffing a 35" tire you may need to trim your pinch seam, and rubicon rock rail if you have one. It more of a tire issue but something to think about. LINK>
  • Your center of gravity is higher which is sort of obvious is suppose.
  • You should give your axle breather hoses some more slack (you should extend them while you're at it for water crossings). I did a write-up about it. The rear axle breather needs to be detached from the rear of the frame which I didn't show.

I'll cast the first vote I guess. :thumb:

Back to the video though, I loved the old guy who said "there's a lot to be said about ego." LOL I really enjoyed his opinions on the matter.

After watching this, I've chosen the same one.

I currently have the teraflex 2.5 BB lift on my 2011 JK right now. Its been on there for 2 years now. I am thinking about changing it up and trying to decide if I want to go with their 3" or 4" lift kit so I can also upgrade to 35's. Very cool thread! Lots of great info!

PhotoWrangler 06-13-2013 08:25 AM

If you watched the video, you can run a 35" tire with the kit you already have.

terrabit 06-13-2013 08:56 AM

You might get some rubbing with 35s and 2.5" of lift, particularly if you disco your swaybar.

weaponx24 06-14-2013 01:03 AM

Yeah if I were to get 35s with the kit I have on there now I feel that it would probably rub a bit. That's why I'm thinking about going with the 3" kit.

TeraFlex 06-14-2013 10:03 AM

I would try it with 35's first. Assuming your factory springs haven't sagged too much you should be ok.

scipio337 06-14-2013 10:10 AM

Now I just wish they'd make similar "Largest tire you can run on your stock JK" video. :D

I'm making the wife watch this one.
