Advice Please!

I am looking at buying a Rubicon JKU take off suspension (springs and shocks), how much lift should I expect on my JK 2dr Sport and should I still get the Teraflex leveling kit as well?

You need to look at the spring rates you have
Last 2 numbers on the tag.

It depends on the spring rates. Just because it is a JKUR doesn't always mean the highest spring rates. You need to check yours against the Rubi's. If you are low on the scale and the Rubi's are high, you may get a couple inches, I think.

One would think that going from sport base to Rubi would deffinitely be a suspension upgrade. Correct me if I am wrong but the Rubi came with an uprated suspension stock right?

OK Thanks for the heads up. I had been reading that putting the JKU springs on the 2dr was an upgrade as they came with higher rated springs on the JKU's, but you never know with the build I guess. The member wants $250 for the springs and shocks with only about 3k miles on them I believe.

It's all about the spring rate, JK or JKU doesn't matter.. And while the shocks on the rubicon are the upgraded factory shocks they were also a option on the other models so you have to make sure you already don't have them as well.

Well I bought a bone stock sport no options what so ever other than A/C and hard top, so I am possitive the shocks are an upgrade

Lowest I believe is 13/55

Highest through Mopar 19/60

If you do have low rate springs, make sure the ones offered are at least 18/58's or you won't benefit much.

I bought some take-off Rubicon shocks from a JKU and the guy tossed in the springs too (not bad for $40). Anyway, I was surprised that the springs were 18/58s and though that was not a huge improvement over my stock ones (which were just under that), I will definitely use them.

Went from 14/55 to 18/59 with rubi shocks. Gained a little more than an inch in height. The difference in the ride is like night and day, a lot firmer, minimal body roll, no nose dive when breaking and much more stable at speed. A great improvement for a small investment. IMO
