Yeah, we talked about this, my Overland springs were about an inch longer than my LE Rubicon springs. They were a PITA to remove.
I know this is an old thread, but I got rubicon take off springs from one that had freedom top and plastic bumper. The numbers are 339AC and 349AB, but I'm not sure which side is which. Do you think it still follows the larger number on the passenger side?
That's a huge difference in spring numbers.
It was a gas Rubicon. Both came off the same one. Unfortunately the dealership just put it all in a box and didn't note which side they came from.
I dont know about the other one, but I had 349AB on my driver side
I bought rubicon takeoff suspension for my Willys gladiator. I wanted to get rid of some sag from winch and steel bumper addition.Don't over-simplify springs. Max Tow rears were SHORTER than the stock Overland by quite a bit, If I recall correctly, a good 3/4 to 1" shorter and yet with the weight of my truck on them, it sat pretty much the same.
Because a spring is 1" longer doesn't guarantee 1" "lift". Maybe - but rates, etc. matter, not length.
Always could be more, could be less. Since the Rubicon is heavier in most cases, then expect more, but length is only part of it as discovered here.
(higher numbered spring always to the right or passenger side)
There's another "bottom line" here - A Sport max tow may be fully equipped and get heavier springs than the truck in this post. The Rubicon springs COULD have come from a lighter Rubicon.
I've said this before - "Rubicon springs" is a trick statement. There are several numbers for Rubicon depending on how optioned the truck is. Same for Sport max tow or not. There will be different numbers depending on the truck's equipment.
So you can not say with certainty that "Rubicon springs are 1" longer than max tow".
SOME will be, maybe most are - but that's generalizing and saying all Rubicons are the same and all Sport with max tow are the same. If the fronts came from a Rubicon with the stock plastic bumper and minus other options, it would have lighter springs.
In this case he got the heavier Rubicon springs.
The set I got was 339 and 340 so the 340 goes on the PASSENGER side for me.
(so don't use the 340 on the driver side as a rule!)
Every level of JT uses multiple spring numbers.
And the two Rubicon rears I have have different numbers of coils! One has more than the other.
These are all from Rubicon - but look at the number of coils in the left or shorter spring compared to the coils in the taller right spring.
All of these are from the SAME Rubicon - fronts on the left, rears on the right.
