I have a bone stock 2011 sport JK 2dr with auto trans and am planning to go with 33" 17"x9" (5" Backspace) and a 2" lift. I spoke with a aftermarket installer who said he had taken a factory lift kit off a new Rubicon and would install it on my Sport JK for $700. He said this would give me a 2" lift and would include new factory springs, shocks and stabilizer...Im not sure if anything else should go along with these componants (??), or whether this would be a true 2" lift, nor am I sure if it is worth the $700 installed ...Your help here is sorely needed!

Thanks,

3 tons

 

If they are talking about the stock standard springs and shocks from a Rubicon the amount of lift could vary, in fact it could actually lower your Jeep. The springs given to jeeps is completely dependent on the weight of the Jeep, not the trim package, the way people get lift by swapping stock springs is if they take higher part number springs like on a 4-door, PN# endings in say 17, 18, or 19 for the fronts, and PN#ending in say 58, 59, 60, or 61 in the rear, and put them in a two door that had lower PN# springs. The Rubicon shocks will give a better, although a little stiffer, ride.

The only thing need to be swapped are the springs and shocks, everything else is identical. These parts can be found very cheaply if not free if you ask around a bit, and if you or a friend have a floor jack and a couple of jack stands you can swap them out yourself in an afternoon. I would not let the dealer mess with it, especially if he is trying to tell you that all Rubicons come with beefier suspension.

Happy Jeeping!

 

To add to this, I believe the 10A Rubicon springs are longer then the ones listed above. I am not sure of the numbers but there are quite a few threads about people who did comparisons.

 

I second that, sounds like your getting bogus deal.

 

Get a proper lift and find a new installer as he is giving you false information and ripping you off. There is no way you are going to get 2" of lift swapping factory coils no matter what numbers you have. These coil numbers are based on coil rate. The higher the rate the taller they will stand and the rougher they will ride. I have never seen the actual rates of these coils but they should be in the 200 pound + rate. In order to get 2" more height on a 200 pound rated coil set the jeep would have to be around 1600 pounds lighter then the doner vehicle and there is just not that much weight difference even between a base 2 door vs a loaded rubicon with tow package. The difference in weight between a unlimited rubicon and a base sport is about 555 pounds. This would result in a little over 1/2" of height if the coils were swapped. Of course hard top vs soft top, additional options, and tow package will affect overall height when doing a swap but you will not get 2"

 

This is true as well. When I did mine, I went for 14/56's to 18/60's and I got about an inch to an inch and a half front a rear. I got my springs for $40 and did it myself one afternoon when I was bored, so for me I feel it was worth it, especially after adding my bumper and winch, but as a method for accommodating larger tires or anything of that nature it isn't really a viable option. It is best considered as a way to compensate for extra weight, not a way to add significant lift.

 

If you decide to do this yourself or just want to know more, hit me up. I'm nearby.

 

Holy crap! I'll do it for half that including the parts (which I happen to have sitting on my shelf in a garage).

To be clear, the only real difference between a rubicon and a non-rubicon as far as suspension, is the shocks. The Rubicon shocks ride a little firmer, but have a little less brake dive and are less prone to overheating in high speed off-roading.

Beyond that, Exactly what Dirtman said. All you are buying is someone's throw-away coils from a heavy factory 4-door. Jeep needs all models to sit around the same height, so each requires different spring rates. Getting more lift off of factory coils, just means you hooked up on some super stiff coils.

Anyway, you'd be a fool to pay more than $50 for all that.

 

As mentioned, no Rubicon spring is going to give 2" of lift, unless you put a spacer on it.
