Mopar makes the coils, fox the shocks and dana the driveshaft. They most people a very happy with them. I think as many people as run this set up i have only read two reports where people were not happy.

 

There are more than 2 people not happy with it - I am one of them. There are some issues with the kit as noted in the Mopar lift threads - the rear trackbar bracket interferes with the frame on some Jeeps - on my Jeep, the bolt/nut hit the rear spring. However, I will agree with you that most folks are happy. I added F/R adjustable trackbars, Rancho Geo brackets, and Sumo Springs progressive bumps. The Geobrackets/lower arms are a must to improve steering/tracking at speed.

This lift is better suited to two door jeeps (like the OPs), as Jeep did a marginal job of designing the spring rates (as JKs are likely not as heavy/nor will be loaded like JKUs).

My biggest complaint is weight handling - the lift does not handle weight well at all. When I first installed the lift, my Jeep was in relatively stock form with little added weight - the lift yielded a nice smooth ride, compliant springs, etc. I really like the way it rode. My lift netted slightly more than advertised, but the springs settled very quickly to advertised height. The warts started to appear once weight was added. Loaded for a few trips, I experienced excessive body roll, the rear bottomed out frequently on freeways (and off road), and had lots of head whip from poor damping in the rear. Run a trailer, and things get worse.

The spring rate is about the same as factory and the shocks are valved very similar to stock Rubicon - not the best idea when raising a vehicle's COG (springs should be a bit stiffer and shocks valved a bit heaver).

I've added some aftermarket accessories since the initial install(winch w/ synth line, rock rails, extra battery, AEV front bumper, engine skid plate) - but by no means, anywhere near what some guys run. With these modest accessories, the ride got precipitously worse when loaded for trips.

After about 30-50k (I can't remember exactly), the rear Fox shocks were done. I lost a significant amount of height overtime as well. By the time I pulled the springs off (about 60-70k? or so later,) I was running 3/4" spacers F/R and was still 1/2" shy of 2" as measured using spring perch/bump stops.

I think the disparity in satisfaction/performance comes in the way people use their vehicles and for how long they keep it - my jeeps sees lots of miles on/off pavement running heavy and while not trashed, is not babied either.

Bottom line - stock jeeps with little added weight and seldom tow, it is a nice lift. Run heavier/go on many trips with a family, or tow - skip it and find a different lift. Look for higher spring rates and shocks valved for greater damping.

Mopar 2 inch lift 77070088 - with Fox Shocks

Anyone installed this exact kit? Quadratech says it has only been in their system since late last month. Local dealer says it is an old part number. I have not heard back from Mopar yet. It is listed in the newer Performance Catalog that is pretty new. Uses FOX Racing Shox 2.0 Performance...

Thank you - I just found that too!

 

Also - why are they putting a front DS in this kit?

On '12 and up JKs the exhaust crossover can contact the driveshaft if you have longer front shocks. Or if it's up on a vehicle lift while the exhaust is hot it can melt the boot on the driveshaft, I think. I'm using the mopar coils with the stock driveshaft with no problems so far but my front shocks are only 25" extended. I'm not sure what the length is on the fox shocks that come with the complete lift.

 

Also, if you have a JK and not a JKU keep in mind that you will get a lot more than 2" of lift. The JKU gets near 3" of lift typically, but the JK seems to get more, especially up front.
But I think it is a good lift, just don't use the cam bolts it uses for caster correction. Instead, buy a set of geometry brackets like from Rancho. Or go with front lower control arms, either adjustable or longer fixed length. But I think the brackets are a better choice, they will give you a better ride quality than the control arms, in addition to adjusting the caster.

 

I have the Mopar lift on my 2dr and really like the way it performs. Because the 2dr and 4dr kits use the same front springs, my 2dr saw 4" lift in the front. Rear springs are specific to 2dr or 4dr and I saw 3" rear lift. This lift definitely levels a 2dr so If you like the rear to sit slightly higher than the front, be prepared to install a small spacer in the rear or modify the front spring for less lift.

 

I’ve got the 2” Mopar on my JKUR. I didn’t use the cam bolts either and instead went with Synergy fixed LCA’s. The ride is great even with stiff E-rated tires

 

Great deal if you can get it for almost 1/2 price. I would do that deal today can you let us know where the deal is or is it a buddy deal.

 

Sorry I disappeared - it was a buddy deal out of ATL and I missed it. :-(

 

Also - why are they putting a front DS in this kit?

The 2in Mopar lift with the drive shaft included is intended for 2012+ JK's. The exhaust is routed under the front drive shaft on the 2012+ drive shaft and after you lift, the stock drive shaft can come in contact with the exhaust, damage the DS boot, which then eventually leads to drive shaft failure. There are a couple ways to fix that problem. 1. The inexpensive way- install exhaust spacers which provide additional exhaust clearance from the front drive shaft. 2. Install a smaller diameter/stronger front drive shaft. #2 is what the Mopar 2in lift provides for that solution.

 

My wife and I each have the Mopar 2” lift on our JKUs (both installed in the last 3 months). Her’s has the Rancho geo brackets and mine the TeraFlex Sport LCAs. She prefers the feel of geo brackets (cushy) and I the LCAs (firmer).

The newer versions of the kit have a revised rear track bar bracket that clears the frame better. I installed both sets of rear springs with the tag at the back to improve rear track bar nut clearance.

Already have a few other suspension parts on order to increase downward flex. A bit peeved that the Rancho 2” Sport kit I removed from mine had longer rear shocks than the Fox units included in this kit.

 

Your comment reminded me of something that irked me the most : I had close to 2" of shock shaft exposed during full compression both front and rear with the Mopar Fox shocks that came with the kit. I thought I figured out the shocks were the same length as the Rubicon shocks, but I don't remember for sure...they might have been really close. Anyhow, I ended up installing Synergy front shock extension brackets and rear lower shock relo brackets to increase down travel...there was zero concern of the rear spring popping out. There was still shaft exposed F/R ... So no issue with the shock bottoming out.

I tried to rotate/index the spring - no dice - the spring would hit the bolt from to time.
