2023 Wrangler JL 2 Door Sport 2.0L Automatic.
32x10 BFG Trail Terrain on Willys wheels. 62.5 lbs total weight per wheel
Rubicon take off shocks and springs from Ebay.

Stock Springs:
Spring#: 228/36 109/110
Stock ride height: measured from the ground, center of wheel, to bottom of fender.
front - 35.5"
rear - 36.25"

New springs:
FRONT Springs
57/58
36 1/2"

REAR Springs
113/114
37” 1/4"


This setup wont work for everyones Wrangler JL 2 door Sport. A lot depends on weight when tuning suspension.
My mods to lose weight:
I rarely carry more than 40lbs of gear.
Rear seat delete w/ belts.
RC winch synthetic, 60lbs.
RC winch plate, less than 20lbs, I'll guess 17lbs.
MP Concepts Forged Aluminum Front Bumper, about 15lbs.
Stock rear plastic bumper.

My review of the Stock suspension compared to the new 1" suspension lift:
Night and Day difference. I just wanted to add a winch but knew I needed the suspension to be able to handle the new weight. I trail tested the front before I did the rear and the front was so smooth I decided I needed to do the same to the rear. The pain in the a## was getting the spring numbers right for the weight of my vehicle. I had to install, test, and return a couple sets of springs to get both the front and rear right. This setup doesn't leave much room for adding weight later but that's not what its built for. I tuned this vehicle to run the forest and desert roads of California with a winch. I wont be bombing the desert any faster than before but it'll be a lot more comfortable. I can definitely move a lot faster along the forest trails. I noticed I can cover more ground in a shorter amount of time. I had to readjust the way I read the trail.

Tips for newbs:
The springs will settle and lower another 1/4" to 1/2" after driving and sitting over night. So don't measure and judge right away.
2 Jack stands and a floor jack is all you'll need.
Remove the rear trackbar and everything will be easier.
Because I don't carry much cargo, I added 15lbs to the rear, to adjust ride height. I added a hitch and recover point. I stowed the recover point in reverse so you can't see it.
The springs all look the same, so be sure not to install the wrong spring.
The install is very easy and can be done in the driveway with commonly available tools.

You should also consider upgrading the front track bar to a HD adjustable one along with Mopar LCA’s. That will really help stabilize the front end, tighten up steering.

Good write up with attention to WEIGHT. Way too many people add things without the thought of the added weight. I really try and make this one of the considerations with my own Jeep along with ride and comfort at my age.

I like what you did, but the when I look the front bumper is more like 41 lbs and not 15?
I added 4 door tow package springs to my 2 door with similar results. The only thing I would add is make sure the parking brake is off, or it limits how far the axle drops when changing the springs.

@JeepTough Glad it worked out.
Here's my install thread and if you scroll to post #4 it details the LCA install along w/ part #s, I highly recommend those LCAs makes steering at hwy speeds easy-peasy!

Need to post up here too, since you're in the club ?

Does the parking brake need an adjustment if a lift (body and/or suspension) is installed?

Not for the 2" lift or less AFAIK

Good write up with attention to WEIGHT. Way too many people add things without the thought of the added weight. I really try and make this one of the considerations with my own Jeep along with ride and comfort at my age.

I didn’t care much about weight with my 2010 JKU and came to regret it. Although it was basically a tank, I sacrificed drivability, fuel economy, and definitely put more strain on the driveline and steering components.

I’ve learned my lesson, and with the JL and keep everything as light as possible and love it! I’m sure a lot has to do with the better gearing, transmission, and increased torque over the 3.8L, but I’ve kept added weight as low as possible and it makes bumping the Jeep over obstacles significantly easier.

Nothing sexier than a black 2 door with a little bit of mud on the sides. Beautiful Jeep!

FRONT Springs
57/58

REAR Springs
113/114

For those wondering:
68253657 & 68253658 = front JLU Sport & Willys 3.6 manual (no steel bumper)
68253113 & 68253114 = rear JLR springs

Also it's worth mentioning that the 4-door front spring rates are likely a lighter spring rate than the 2-door springs they replaced.

For reference, I gained about 2” from a Rubicon spring swap. Currently rolling on 35’s, drives straight as an arrow. As mentioned, an adjustable HD track bar and upgraded LCA’s make a noticeable improvement in drive quality. Load C tires also help.

 

[TheBirdie72]

I did the rubi spring swap and picked up 2 inches all the way around. Adjustable LCA’s are awesome. Stuck with 33” tires to keep weight down. Two doors don’t necessarily need 35” tires….

Wait…what did I just say? ?

I went from a load E 33” tire to a load C 35” tire and the weight was about the same. Load C tires are typically much lighter than an E range one.

The real win though is that I scored 5 brand new 33” Falken Wildpeaks (they only had 400 miles on them) from a friend that was upgrading his Gladiator Mohave to 35’s… for $700 ?? And the tire shop even mounted and balanced his takeoffs on my new pro comp rims for free when they did his! Best takeoff deal ever. ?
