Hey everybody,
I have a 2dr sport JL stock as can be. I just bought a JLUR Ecodiesel suspension. It had a hardtop but not the steel bumpers.
I have done as much research as I can in these forums but there just isn't a ton of data on the Ecodiesel suspension in here (atleast from my digging)

Everything i have read leads me to believe the coils should have separate part numbers for front and rear, driver and passenger. Mine don't.
Front part numbers are 3667AD and I measured them at 19" a piece
Rear part numbers are 3601AA and I measured at 14 5/8"
The only difference between them is Load ID and one of each spring has a green tag

From what I have read this opens up many questions. This is my first time dealing with a suspension swap. I do work in the automotive industry but all my knowledge is in electrical harnesses and the interior of a vehicle.

I'm a little lost when it comes to this but any thoughts or tips on installation would be a massive help. I also have ordered the mopar lcas because I assume this will be on the larger side of the Rubi lift heights.

Will be interesting to see what kind of negative rake you get. The diesel engine is 375lbs heavier split between both front springs should be at least an extra 1" height in the front.

The 375 is spread out amongst all the extra components the 3.0L diesel requires.

@Aintsfan25 I find it funny that the diesel or at least the Rubicon diesel seems to have the same springs for the left and right side. A while back closer to when I first joined this forum I saw the talk of passenger and driverside specific springs and I didn't believe it. Didn't make sense in my mind. Now come to find out the diesel might not, it's just interesting.

Anyhow, I'll be watching to see how this works out for you. I'm betting it's gonna be a killer setup that many will move to in the future.

Can you measure the overall width of those springs? Not the spring could diameter, but the space it takes up (our Jeep isn't here yet and I end up asking all sorts of silly questions that seem like I might be able to answer for myself).

375 for the engine and 425 total package according to Mauro Puglia, the FCA NA head diesel engine guy. If you have better info from a better source post it up.

Yes sir I will measure everything tomorrow morning! I'll update on the findings.

I do not, but once I remove all the extra emissions crap I'll let you know what it weighs, maybe it'll be 50lbs worth of stuff.

You will probably get yours installed before mine so I would love to see how it turns out. Also do you have any part numbers or anything that I can use as a reference for mine?

Unfortunately I don’t. The guy I’m buying them off of got everything removed this week and it’s all sitting at the shop. I also have a 1” leveling kit and some 33x12.5xr20s on it right now (Moving to the Rubicon 285/70/r17 wheels/tires). The shop has a spare set of stock wheels I could have them throw on to take before and after measurements.

They shifted the drivetrain slightly passenger and moved the fuel tank to the driver's side. The diesel is much more balanced left/right than the 3.6L gas. It has been interesting seeing the differences as we are developing diesel JL suspension. There is a ton of small details that they changed, simple details like the location of the breather tube on the rear axle is on the driver's side rather than the passenger side like a gas engine. Lots of small details.

First time I've read an explanation on here, thank you.

Can you please measure the shock eye-to-eye lengths both before & after install?

You definitely need the longer mopar lca’s to fix the steering caster.

I put 4 door hardtop rubicon springs on my 2 door sport and im super happy with it on 285/70-17’s.

if I ever get 35’s i’ll throw a 1.5” spacer in.

I just picked up some 305/65/r17s on rubicon hard rocks from a jk. Brand new, Im currently trying to get them to fit on my tire carrier, did you have an issue with yours? My rear view camera cover won't fit and I had to take the bumpers offs
