@yzinger

Seems from what you posted on your spring location. Seems mixed as far as the normal goes.

On my wife's 2022 overland ( yes I have 2 gladiators )
Rear springs ending in
117 drivers side
118 passenger side is also opposite of what is considered the norm



@Hootbro

Is there a better way to go to give a little more lift and improve off road with out hurting on road drivability to much?
For GAS powered Gladiators - highest numbered spring goes on the right due to fuel tank location being on the right.
I've never paid attention to the even/odd number situation. Maybe things have changed but for the earlier springs, I go by the numbers hierarchy numerically - higher number on the right.

If you look at my 2022 front springs, both are even numbered.

Look at my 2020 - odd numbers on left, even on the right, but regardless, it's highest number on the right.

So I had a chance to look at the tags on the springs installed on my 2021 Willy's

Front
Passenger side
68341325AB

Drivers side
68341324AB

Rear
Passenger side
68341440AC

Drivers side
68341439AC


Rubicon take off
Front

Passenger side
68506362AA

Drivers side
68506361AA

Rear
Passenger side
68506211AA

Drivers side
68506210AA

Based are the part numbers are the Rubicon springs stiffer than the Willy's?

I am just trying to understand the part numbers and their meaning

I don't think anyone has actually determined rates from the numbers.
It could be assumed that the Rubicon springs are a higher rate spring. The Rubicon truck is heavier in most cases.

There will be different lengths as well as spring rates ("stiffness")

Max tow rears are supposedly a dual-rate spring. They are a lot shorter than Overland rear springs, just as an example, but hold the truck at the same height - so they must be a higher rate spring.

What @ShadowsPapa said. There is no master list of part numbers and spring rates, just anecdotal threads here or there of people posting what they have taken off and what model they were from.

When you ever get around to taking off and replacing your Willys springs with the Rubicon ones, you will notice when you put them side by side, the Rubicon springs are slightly longer in length and the coil diameter themselves are also larger. Does not take a rocket surgeon to figure out the Rubicon springs will be stiffer to some degree or the Willys springs.

Before I talk springs below - a tip or three on what to watch when swapping springs on these.
They have insulators or isolators at the top. They fit into the "cup" where the top of the spring goes. They have nipples on them that line up with holes in the Jeep's structure to hold them in place and prevent them from rotating. They tend to fall out when you are swapping springs.
I found for me, doing it alone, I needed a way to make sure they stayed in place AND those nipples were in the holes where they belonged.
I wiped off the isolators really well so they were clean on top. I wiped down the cups where they went into really well. I then used some 3M 008001 Super Weatherstrip Adhesive on the tops of the rubber spring isolators and stuck them up in place making sure the nipples on the rubber went into the holes where they belonged. The 8001 is sort of like a contact cement in a way - stick the parts up in place, pull them out for a couple of seconds, then put them back in there. They'll stick in place.
The rears are especially a pain because you can't really feel up on top to make sure those nipples that locate the rubber isolator are in place.
Use whatever tricks you need to to keep those in place.
PATIENCE is the key. Don't hurry, keep cool.

Springs -
Pay attention to the wire size as much as other factors - the wire size, coil diameter and coil spacing varies with some.
Here is a Rubicon spring - I could be wrong, but the varies spacing, wire size and coil diameter in the same spring suggests something.

The Rubicon spring -

Overland springs - just for comparison. They tend to be long springs, but with a low rate, offer a soft ride. They don't support a whole lot of weight very well but man do they ride nice!

Got everything installed today.

For the front I ended up a little less than an inch up front gained. Not sure about the rear. I forgot to measure.

Front from the ground the the sharp ended at the bottom of the fender

Front 36 3/4
Rear 38 3/4

Steel bumper and winch are not installed yet. I will have to see what that does to the front.

Worried it may pull the front down more

It will likely but you could install 3/4" daystar spacers up front.

Because I forgot to measure the rear before I did the swap I have no clue what the stock rake was.

Can anyone tell me what the stock rake should was.

Mine is a Willy's with gas motor, automatic trans, hard top, tow hitch.

Installed the front bumper and winch yesterday.

Looks like it added about 3/8" sag to the front.

I was at 36 3/4" I am at ~36 3/8"

Seems like it should be ok.

If I decided to do 3/4" leveling blocks would I need to change anything else?

Getting ready to install the Daystar 3/4" leveling blocks.
The instructions are not the best.

I am assuming these go between the top of the spring and the isolator.

Just want to make sure before I start.

These are as close to two apple to apple pics that I have (first one is pre-bumper and winch). However, they both are when the truck was on 35s and had stock fenders. The top one is Rubicon takeoff suspension and a Teraflex level kit, the second one is with the 3.5" lift I got.

That looks great but does not answer my question on where the Daystar leveling blocks go.

On top of the front springs.
If you use the rear 3/4" spacers, those go UNDER the rear springs.
but
The fronts go on top of the front spring. They are shaped to fit over the coils on the top of the spring, and the top of the 3/4" front spacers are rounded similar to the spring coil would be to fit up into the spring's top support area.
In short, top of the front springs with the rounded part on top, the top of the front spring into the area on the bottom of the spacer.
