|kjeeper10||Currie w/ JJ's|
|Yesterday 07:30 PM|
James Adams (Adams driveshafts) is a great dude to work with. I own a front and have had no issues.
If doing both uppers and lowers .. Almost any arm will work. Uppers only, I'm not too sure of the measurements.
I have a set of CURRIES here and they are set 1/2 longer then stock and can go to stock. I'm thinking 1/2 maybe 3/4" longer should work.

I measured a good 7-8 jeeps using the method in those pics (2 and 4 door)
201/4 front and 211/4 rear is a pretty good estimate. Some of the jeeps had less of a rake and measured closer to 21 up front.
I was up over 4" With RK's first gen coils. The newer triple rates give more of a rake and not as high.
|Yesterday 01:57 PM|
|Yesterday 01:57 PM|
These coils don't sag much at all. I can set on my bumper and it drops maybe 1/4". I weigh just shy of 200 lbs.
I run the 2.5's. W/ only a 75 lbs front bumper. I'm at 3.5-4" up front and 3-3.5 out back.
Now take it to consideration where the person is measuring from. The flares are not a good spot to measure. Coil measurements before and after will get you the most accurate numbers. Wait a few days after install too... The coils will settle some.
I don't doubt 3" with 1.5's on a 2 door. Loaded up, a little less. RK coils take weight like a champ.
|Yesterday 01:55 PM|
STOCK 2 door with RK 1.5 coils:
|Yesterday 01:40 PM|
To summarize: FULLY outfitted 2 doors are getting over 2.5"! A stocker will be @3" no doubt.
Anyway, go to page 4 in this thread and see for yourself (theres other 2 door examples throughout this thread as well):
|Yesterday 01:37 PM|
Tech the RK coils are rated for a 4 door. You'll get similar results running TF's 4 door coils on a 2 door. Now I don't know TF's rating for each.

|RFC89747||2 door. So with a TF 1.5 performance leveling kit I will have slightly over a 2 inch lift and it will handle the extra weight of bumpers/winch well? If so that sound like the kit I should get.|
|Yesterday 11:11 AM|
4 doors are averaging 2" and 2 doors slightly more. Neither over 2.5 where you have to worry.

Teraflex 2" Level
Went on yesterday in about two hours with a lift and a helper.
Left the front bushings in for a little extra.
Some clicking or rattling is going on as it all seats again, so I'll try and isolate that during some off-roading today.
Looks great even with the 32s.

Spacer leveling kit
I added a spacer leveling lift to the JKU RubiconX that has a Warn 10s winch. The quick summary is that I am about 1.75" taller in the front and 0.5" taller in the rear than a nominal/stock JKU. The Jeep sits approximately level and the ride is perfect! The on-road manners are wonderful. A picture is provided showing the results. Additional details are provided below on the leveling kit for those interested.
Fig 1. A picture of the leveled Jeep
The JKU RubiconX comes with 0.5” of lift (front and rear). I added a Warn 10s winch, which caused the front suspension to sag slightly more than 0.5” so a spacer lift kit was in order. I purchased the Synergy spacer kit ($100) from Quadratec to correct the sag and to add a small lift. The front spacers are 1.75” tall and the rear spacers are 7/8” tall. The rear spacers were advertised as 0.75”, but mine measured about 7/8” thick – perhaps they sent the wrong rear spacers. Because of this, I did not use the rear spacers since the 7/8” rear spacers would create too much rake (i.e. the front sits low relative to the rear). I hope that Qaudratec will exchange the rear spacers for 0.5”, which will add 0.5” of rake. A little rake is helpful in some situations (e.g. loaded down with camping gear).
The JK has a total of about 8.25” of vertical front wheel travel - the distance between the strike pad and the top of bumpstop. An image is provided illustrating this distance.
Fig 2. An image of the front suspension vertical wheel travel (8.25")
After the front spacers were installed, there was about 5.25” of vertical up-travel of the suspension, which means there will be 3” of down-travel (8.25”-5.25”=3”). A picture is provided illustrating the vertical up-travel at ride height. I like up-travel for absorbing bumps so I find these values favorable.
Fig 3. Picture of the final front suspension up-travel at ride height (5.25")
Prior to the spacers and the winch, the RubiconX had 4” of vertical up-travel; in other words, the front has 1.25” of lift (5.25”-4” = 1.25”) over the original RubiconX. I am about 1.75” taller than a nominal/stock JKU because the of 0.5" lift springs. The breakdown is 1.75” spacer + 0.5” RubiconX springs – 0.5” Warn 10s winch = 1.75” of lift in the front.
Next, the front swaybar was originally close to level, but it is now about 1.5” to 1.75” lower than level. I attached a photo of the swaybar measurement.
Fig 4. Picture of swaybar angle at ride height
Based on trigonometry, the front sway bar will be angled downward about -7.4 degrees with 1.5” of vertical drop or -8.7 degrees with 1.75” of vertical drop. Many people recommend keeping the swaybar +/- 5 degrees with respect to level, which means that I should add 0.5” to 0.75” of length to the front swaybar links. The front swaybar links are currently 5.25” long and I was unable to find a swaybar link that was around 6” long and compatible with the electronic swaybar disconnect. As a result, I plan to live with -7.4 to -8.7 degrees unless I experience an issue. The Jeep drives great and there are no warning lights. If someone knows of issues with this swaybar angle range and a small spacer lift, then please send me a note. I did verify that the swaybar will not invert at full droop with the stock swaybar links. Please see the picture above showing the front suspension at full droop.
Next, I have not added any spacers to the rear suspension yet. The vertical up-travel at ride height remains unchanged at 5.5”. A picture is provided illustrating the rear up-travel on the RubiconX. I will measure the total, vertical rear suspension travel if I can exchange the 7/8” spacers for 0.5” spacers.

In closing, I hope the information in this post is helpful. Best wishes…

|Time||I'm going to get this worked in to my schedule this week ( it's not a DD) and hopefully get parts ordered if the local off-road guys can get on board.|

Wow, thanks for your insight . I really appreciate your hospitality and looks like we will be getting new DS, CV and Control arms this week .
I'm new to the Jeep world and I want do what's best and don't like spending "stupid money" on "upgrades " and wished I was better informed on my build in the early stage. Thank friend

Adams was the cheapest for awhile until manufacturing cost went up and they switched to solid u-joints.
I run a front Adams and it's treated me well.
I actually have a spare stock sitting here if it goes. I found it for $75. No issues yet with no pinion angle correction. I also have upper Currie arms for when/if it does. I'm ready
My advice to most people... . Run the stockers until they die. You will not have to worry about the front because it's not under load in 2wd. Plus if it goes .. You can remove it and drive no problems.
Get the rear fixed up. Like I said, you will need to run (at min) a set of upper control arms. A friend runs TF uppers w/ her AEV 3.5" lift. Just enough to tilt the pinion up lessoning the angle of the DS.

Here is the joint

Do not drive it like that.
2 door I assume ? 3.5" is a good amount of lift on a 2 door. Best bet and if lucky .. You can find a takeoff in the classifieds/eBay/CL. Swap it out, then think about adjusting for more pinion angle.
* Aftermarket double carden DS. You will need adjustable control arms with a double carden shaft.
* Crown (I believe) now makes rebuild kits for the stock Rzeppa (CV) joints. There's a couple excellent writeups on the forums.
Where are you located ?

|Time||I've got a 2013 jk sport with a 3.5 "Rough Country with 8000 miles ,just got home From 150 mile trip and decide to run an errand and now the rear drive shaft has grease "splatter " up near the transmission and want to lurch and not drivable . Do you think factory warranty will cover ?|
