Ride height by model

[AnnDee4444]

Sports don’t need extended length shocks because they don’t have e disco like the Rubi.

That's one way of looking at it, but you missed the point... Sports have a shock length of 21.5", and you're stating that they ride at 20.5". If this were true, the Sports would have less droop than just about every car ever made.

you are not gonna see 2” gain from 4door Rubi springs on a 4dr sport. That right there make a swap pointless.

I agree with neither of the two of you, or more accurately, parts of each, but that thread you linked is putting Rubicon springs from steel bumpers, tow package, etc. on a soft top.

And they measured a "2” gain from 4door Rubi springs on a 4dr sport."

What have I stated that you don't you agree with?

Nothing. I may have misread it as an assertion that the ride heights are 2" different. Sorry. I see you were just rebutting the fact of a 2" gain under certain conditions.

I will say that Jeep sucks with getting the ride height as advertised, and that all trim levels are probably ±0.5".

They only see a minimal gain because on average the rubicon's are heavier But not all 4dr to 4dr see gains. 2dr with 4dr springs yes. Most of it is a myth. If you play the game and watch the part numbers you may see gain but you are not gonna see 2” gain from 4door Rubi springs on a 4dr sport. That right there make a swap pointless.

I never said "all", but rather in a general sense. There are certainly exceptions to the rules, but that doesn't make them the rule.

The point is that there's no absolutes on this specific topic. In general, most stock Rubicons sit taller than a comparably equipped Sport or Sahara. And that's due to both tire size and suspension height. And I'm referring to the 3 main models, not the mix and match parts bin and appearance models.

This argument went on for years with the JK as well. And yes, You are correct, There are no absolutes. It’s a one by one deal.

Bottom line is and it doesn’t change the fact that OEM springs are weight rated not lift sized or intended. The only reason they give lift is because of a heavier weight rating as I explained a post or two back. If they sit higher then stock average you loose free length.
Measure for yourself from front bottom spring base plate to upper spring perch lip and see what you get and I’ll tell you how much lift you have.

and when you come back here with a number I’ll tell you what the number is (with video proof) of a base 2 door sport with no mods.

All I know is that when I looked up the springs for a Rubicon with the same top and bumpers as my Sport and saw that the front springs were identical (the Rubicon had a tow package that I didn't have so the rears were higher), it destroyed any notion that the Rubicon is supposed to have a higher ride height. If that was true, Jeep would never let even one Rubicon model ship with the same springs as a Sport.

Exactly what I’ve been trying to say all along. In the JK world the only guys interested in Rubi springs were the 2 door guys searching out FREE 4door Rubi springs preferably dual top, tow package models.
If the Rubicon was suppose to be taller it would also have different trackbars and swaybar links then the sport or Sahara, just like the XR does.

At the same time though, it seems to me that many Rubicons are taller than the Sports. So I tend to think Jeep stiffens and lengthens the springs for extra loads (winches, rock sliders, etc.) on the Rubicon and lets the height float up by an inch or so under lighter loads to accommodate various loads. Better to be too high on the off-road model than sagging.

It’s deceiving with Rubicons taller tires and highline fenders.

If I worked at a high volume Jeep dealer I'd measure all the incoming Jeeps with the same equipment and do a formal study.

I do have measurements for a base sport 2dr to compare. I’m still waiting for others to post their numbers up.

I recently swapped in rubicon springs onto my JLUW. I increased about 1.25” ride hight by going from 58/59 to 60/61 and 87/88 to 91/92 spring rates. I’m rolling on 285/70/17 A/Tx grabbers and sitting about .75” lower than a JLU recon w/35” tires. I parked next to one on a relatively level surface. My JLUW is a 6 cylinder, auto with hardtop. Like others said, you need to verify your current spring numbers compared to what your getting off the ruby swap to ensure it’s an upgrade. Another note is ruby fender flares are high top, so ride height appears higher, but really it’s just wheel well clearance. I plan to install 285/75/17 tires to gain another .5” of hight. Also, level up to Mopar LCA’s.

The height difference between a Rubicon and a Sport is not solely based on its tires though. The Rubicon has slightly more than an inch of ground more than the Sport. The tire size can only account for 3/4" of that clearance.
