Coil spring part numbers

[WXman]

This is the tag on the passenger side rear coil spring from a Max Towing model.

Can someone with a Rubicon post pictures of the same tag? I'm curious if the numbers match or are close in sequence.

Oh yes. Been waiting for this

Rubicon:

Well there we go, the rear coils on Rubicon are different.

So it really is a combination of spring rate, axle width, gear ratio, and transmission that causes there to be so many payload and towing numbers across the Gladiator lineup. It's like Baskin Robins... so many flavors.

if Someone could be so kind to post Overland spring numbers too?

Interesting, wonder if there is really any najor difference in spring rates. Or if the ruby springs are just slightly different because of the fox shocks

I would agree that it is probably the shock difference.

isnt the rubicon slightly lifted compared to the other trim levels

So, on the JK Wrangler the way this always worked was that the higher the part #, the taller/stiffer the coil spring.

Looking at these pictures, the Overland is lowest, then Sport with Max Towing, then Rubicon. So, it seems that all makes sense.

Can some other folks post your rear coil tags? I'd like to see a few more Overland, Rubicon, Sport and Sport w/ Max Towing JTs just to confirm.

Wonder how the springs in the Mopar 2” lift would impact payload and towing capacities? I have a sport S with the max tow package and I am trying to decide whether to lift or not pending the impact.

That is an excellent question, and it's the reason I won't do a coil spring lift on mine until Old Man Emu has their stuff on the market. They actually publish spring rates and load capacities for their coils.

Thanks for the thread.
Do you guys mind posting the front numbers? I have a bunch of different height JLU springs laying around. I'm just wondering if any of them will level the truck until I decide on a full suspension(I know the rears won't work).

I looked at a Sport NON-Max Tow model this morning. It's rear passenger spring was a 439, the lowest I've seen on a Gladiator so far. So it's even shorter and/or softer than the Overland springs. Ouch.
