OEM Rubicon Springs

[Kman]

Will OEM Rubicon springs provide any lift in a basic TJ?

[nagal]

There is a lot of misinformation about this. Except for the first year Rubicons, Rubicons use the same springs as a 6cyc TJ.

If you have a 4cyc TJ then they will provide some lift (1" from what I have read) but so would any 6cyc TJ coils.

so how do the rubicons get that extra lift over the TJs?

The springs are a slightly higher spring rate to help with the extra weight, but the tiny amount of lift comes from the front spring isolators, which are slightly thicker than the standard ones.

It's really minor. . . . Rubicons only come with 31" tires and you can fit those on a stock TJ just fine (without disco'ing).

I thought the rubis came with a 1" lift.

Well, it does sit 1" taller, but 1/2" of that is the taller tires. . . I never measured them, but I'd guess 1/2" from the springs/isolators.

Here is a easy way to tell. Go out and measure the height of your front springs, bucket to bucket. My '03 rubicon with 36000 miles measured 12". Subtract your spring height from 12", and you will have how much lift you will get from adding the rubicon springs.

Assuming that his rig is the same weight and spring isolators are the same height. . . .
