|Thracks||Do lifts actually increase wheel travel for high speed bumps and catching air and whatnot?|
|06-04-2011 08:46 PM|
To give you an idea about the shock extensions. My stock 2door had 97mm down travel remaining on the front and 88mm remaining on the rear til the shocks reached full extension. If you stick 2.5in coils in, with no steel bars you will get closer to 3in (or 75mm).
With the stock shocks this is going to leave you with only 1/2 inch or so down travel remaining on the front and just under an inch on the rear. the slightest bump in the road, or even spirited cornering will see your shocks reach full length!
So you either need longer shocks, or extensions to make your shocks longer. OK, so we stick the 2in extension on your stock shocks and now you have that extra down travel you need to ride properly. However, the compressed length of your shocks is now 2 inches longer than it was. If you disconnect the sway bar to get some good flex over bumps you will push your diff up til it hits the bump stops. Stock setup will have the shocks with 2in travel left at soft bump, push it harder and compress the bump stops and you will have less than an inch shock travel left. NOTE: you DO NOT want to have your shocks bottom out, they will not last very long!
So now you need to fit bump stop extensions so that the axle hits the bump stops before the shock bottoms out, so you will need at least 2in bump stop extensions!
Got that all sorted, now you diffs will be 1/2 in off to one side as the track bar is now too short at this new height as its angle has increased. So for the front you will want an adjustable trackbar (as 2.5 to 3 in to not high enough to fit a high steer kit), for the rear I would suggest a track bar bracket to either drop the top end lower or lift the bottom end higher (not going into the pros and cons of chassis mount vs axle mount at this point) to flatten out the track bar closer to stock to reduce the bump steer in the rear. Bump steer in this case is when you hit a bump, the springs compress and the track bar flattens out pushing the diff sideways back toward the middle again, making the back end of the vehicle wiggle over bumps. Flattening out the track bar reduces this.
Hope all that makes sense!

|vecter11||Ya im a lil bit comfused about the lift as well ( teraflex ). There are 3 lvls and i understand the kit with the shocks but i dont understand the one with extensions....are the extensions needed?.....is the base kit good enough that i can but shocks later?....do the extensions give a lil more boost?....anyone know or can help?|

So I didn't want to hijack anyone and i doubt it deserves a thread of it's own so I figured the bet was to slap this on my own thread since I'm satisfied that my fellow jeepers have more than sufficiently answered my OP.
I just had an entire TJ loaded with Coed Cuties wave their little fingers off at me.. I was all excited there for a moment thinking I was being eyeballed by some potential dates... Then I realized I was enjoying my lunch in my JKU and it was just your standard jeep On the upside, being accepted by a TJ makes my JK all giddy with excitement. She's really started talking to me lately :chanting: winch. winch. Winch!

|97wrangler-242||Also, you can get in to the vendor spotlight forums on here and ask around. Very helpful people|
|05-29-2011 04:28 AM|
|97wrangler-242||I like rock krawler just because it's so upgradable and has a life time warranty. You break it, they replace it, for life. Also, you can start out with just some 3.5" coils and later on down the road slap a long arm kit on it or even a 3 link set up. It's all set up so you can slowly build up what you have instead of dumping 3 grand in to a kit all at once|

|wrangler02tjcarl||skyjacker is junk ive ran it before, maybe lasted 15,000 miles. id say go with a 2.5 long arm kit if you wanna maintain a stock ride but still looking for that rockcrawling flex. I would say go with the long arm now because you will want one eventually. DO it right the first time. i love my 5.5 rubicon express long arm. It is built bomb proof and has lasted a good 50.000 miles. Rides nice too|

|RazorbackMac||So I checked out some Teraflex 2.5" lifts and I've found that the same kit is available in three different configs... With VSS 9550 shocks, with shock adapters to reuse factory shocks, or no shocks included. Is there anyone that could compare VSS 9550 shocks to stock rubicon shocks? Is there anyone that would advise against using shock adapters? Just FYI, the dealership said the islander comes with a factory rubicon suspension and shocks. Secondly, the jeep only has 3k miles so the factory shocks are practically brand new. Decisions decisions...|

|RazorbackMac||Is 2.5" enough... where is steve carell when I need him|
|05-28-2011 11:28 PM|
|millfire517||You might look into the 2.5 teraflex coil lift.|
|05-28-2011 11:26 PM|
BUT, keep in mind these aren't really necessary until you get up into big tire + big offroading territory. Driving around with even 35s on the street, or even moderate offroading, isn't likely to truly require these. They're relatively low cost though, so worth looking into if you're already getting other work done.
|05-28-2011 11:18 PM|
They are re-enforced steel plates welded to your C's on your front axles so to strengthen them and hopefully keep them from twisting or even breaking on the trail

|RazorbackMac||as ridiculous as this sounds, I have no idea what a gusset is... And that excites the crap out of me.. I love learning!! Something new to read about... :iwishihadthreethumbsrightnow:|
|05-28-2011 11:00 PM|
|rics1997||Sorry, didn't caught that. The unlimited is 3.5" safe. Some 4" have worked for some. I would recommend 3.5" but if you want a 4" you might be alright. There have been some that have had issues with the 4" though. But a 3.5" lift can go up to 37" tires if you like. The only bad thing about 37" besides cost is that your Islander has D30 axles up front and will need sleeved and gussets to handle the stress. If you really want to off road even 35" could use at least gussets which aren't too much|

The problem here is--totally unknown to you--your question is actually incredibly broad and there's no "right" answer.
There are many three inch lift kits that are complete and of high quality. Much of the rest boils down to preference and what you're looking to accomplish.
Any 3" kit will let you fit 35s, though you'll need new wheels with less backspacing or at least wheel spacers if you ever want to make turns.
Try looking at the TeraFlex products. They've got a broad line up across the board and make pretty good stuff. Review the descriptions on their site and so on, and then compare the offerings of competing companies. That should help hone you in on what you're looking for.
|05-28-2011 10:57 PM|
It's a good idea to beef up your front dana 30 if you want to go bigger than 33s. The axle will hold up just fine on the pavement, but off road it's just another thing to worry about.
Stick around on the forum. There are plenty of people willing to help out a fellow jeeper.

|RazorbackMac||About my profile, I haven't updated it since I traded the 2 door 08 for the 4 door 2010. I guess I should jump on that so I can get the most relevant help...|

|RazorbackMac||I wanna thank every body for input. Thats not to say I wouldn't like squeeze more out of this thread, but thanks for the pre-warnings. I appreciate the dedication everyone has for keeping and helping teach others... The only thing my parents taught me about working on vehicles is how to fill out a credit app so firestone can fix whatever just broke.|

|TJe0454||skyjacker makes a middle-of-the-road product. not the best, not the worst. i love my skyjacker kit on my TJ. now u cant say you've never heard anything good about skyjacker ZOMB1E|
|05-28-2011 10:44 PM|
|RazorbackMac||35" tires seems to be super popular and considerably cheaper than 37's so I'm looking at most likely 35" tires. So how much could I expect to spend on a 3" lift? I want a kit that comes with every single part I'm going to need, I hate starting a project just to realize I'm going to have to leave it in pieces until I can afford extra parts I didnt know I needed... Especially since it's my daily driver|
|05-28-2011 10:37 PM|
Before looking at lifts you should figure out what size tires you want. 4" would be too much if you're keeping the stock 32s.
I've never heard anythig good about skyjacker lifts. I haven't owned one either, so I don't know.
|05-28-2011 10:35 PM|
|RazorbackMac||So even if I went with a 2.5" lift, which of the listed kits do I need to look into? If all I need is a $500 lift, then sweet. If that's just gonna be a huge headache, then which one would be best?|

Well, 2 dr JK's have a bad flaw when it comes to lifts. 2.5" is the only safe lift you can get on the 2 dr because of fatal angle of the drive shaft. If you plan on going over that you have to do drive shaft changes because the U-Joint boot will rub causing the grease to run out and failure. Not to mention other issues that can arise.
What you will have to do is a double cardin U-joint style drive shaft if you want to lift your Jeep JK Wrangler past 2.5". This will increase the cost of the lift to get a good drive shaft. You need to look into Tom Woods Driveshafts.
The JK sits higher then previous Jeeps and really doesn't need more then 2.5" to get large tires under it. 35" tires will fit easy and with flat fenders, 37" will work great. Lifts are not the big issue on the trails, it's the tire size. Lifts help you get bigger tires.
