Want to convert "Sport" to "Rubicon" Help!

I bought a 2010 jeep wrangler sport last year and love it! I put black 17x8 wheels on it and a light bar on the front with IPF lights. I want to convert it to a rubicon though. What should I do without crazy breaking the bank? List your suggestions...

Thanks!

The major cost involved would be the front D44 axle and the 4.1 transfer case. The lockers, suspension, and disconnects are all do-able.

Yea I'm going to take that a step further ... trade up and take the loss - adding elockers, ediscos, 44's front and rear, the rock transfer case, rubi shocks etc to "make" a Rubicon would cost more than the loss you would incur through a trade in. Even if you did pull it off, you would never have the resale value of a Rubicon later down the road.

Years ago, I wanted to do something similiar with a Mustang ...

So the question, what specifically are you looking for in converting a sport to a rubi?

It wont ever be a rubicon, but you can make it better. Id rather have a sport anyways so I can dump the money on things that I deem necessary. A good friend of mine has the exact jeep I do, but his is a rubicon, and he honestly rarely has to use his lockers because hes a good driver. I think the coolest thing about the new rubis is the electronic discos, super convenient. If I was you, Id throw some evo c2 gussets on your dana 30, a locker in the rear, and a good set of sway bar discos and call it done.

Thanks for the suggestions. I am a rookie at this "Wrangler talk" can you put it into simpler terms on what this will do for me? To answer your question, I just want a little more off road edge to my wrangler.

Thanks again.

Yes, and if you can get for cheap off off Craigslist or something, it'd probably be a good edition.

Otherwise, you can "duplicate" it (maybe better, actually) for about $420 using Chrysler HD coils and a decent set of gas shocks.

Yes. It's just stiffer coils and gas shocks. Some Sports actually come from the factory with stiffer coils than a Rubicon.

Thanks for the answers! Mine feels pretty stiff stock (2010 JK Sport)! I was just wondering if it'd lift it a tiny bit by using the Rubicon suspension components, and if it'd be better quality over the stock set up?

If you found springs off an unlimited rubi with the tow package you would probably net almost 2 inches of lift, assuming you have the softest springs.

Possibly it would depend on what coils you currently have. You can check by looking at the tag that is on your current springs. The last 2 digits of the number are the important ones. They range from 13 to 19 in the front and 53 to 60 in the back. I had 14/55 and got a 2" lift when I went to 19/60.

re: spring #:

can that number be found in the build sheet or is it only on the actual spring itself?

I would think it would also be on the build sheet.

As I recall, my build sheet didn't reflect it.

Look at the last two numbers (not letters). You've got 13s and 55s. HD coils would be 19s and 60s. On a two door, I'd expect about 2" of lift.

ok Im confused with all this talk about the different springs. I have an 2010 Jeep Saraha and the Jeep website says the Saraha actually sits higher then the Rubi. Why?

35s, perhaps even 37s if you don't mind rubbing like crazy. However, for those size tires there will be more than the lift that you'll need to do and they'll murder your gas mileage.

A lift will give you better entry/departure angles, better middle clearance, more articulation for your wheels, and looks cool. There are cons too, though.

Chrysler has a number of different coil springs they use in Wrangler suspensions. Hard tops, 4 doors, tow packages, and Rubis tend to get stiffer springs. A result of the stiffer springs is to effectively lift the Jeep.

I doubt that about the Sahara.

What will what do for you? Bunch of suggestions flying around here, so not quite sure what you're asking . . . .

Cool, So with the full suspension set off a rubi (does it matter if its 4dr or 2 dr?) I'd gain about 2"? How much is worth it for a used set with 10k miles on them: "Front & Rear springs all 4 shocks, front & rear lower axel track bars, front track bar, front & rear sway bar end links and bump stops"

You can't tell without knowing the numbers on the coils. Not all Rubis come with the stiffest coils.

Also, I don't think you'll need anything other than the coils and shocks. Everything else--I believe, unless somebody corrects me--is the same as what you have now.

Finally, you could get brand new HD coils and gas shocks for about $420.

Main differences - front and rear diff locks (the sport has the Electronic Brake Lock diff which simply applies brakes to a spinning wheel) D44 front diff (heavy/stronger than the D35 on the Sport), lower ratio transfer case for super slow crawling (4.1:1 instead of 2.4:1 or something like that), 4.1:1 diffs instead of 3.21:1, slightly stiffer suspension and usually a bit better shocks, electric front swaybar disconnect.

I think that about it

Go to Jeeps website and compare the two. It's a very slight height difference but the Saraha does sit higher probably due to the Saraha has 18in wheel and the Rubi 17in.

Depends on who is behind the wheel.

Yes. Rubi has gas shocks, sahara/sport have hydro shocks.

I didn't see anything that shows a height difference. The wheels have nothing to do with it since they both sit on 32" tires.
