Is this true? For four door as well as two? I was not aware of this. I have read about people putting rubi springs on non rubi and seeing a slight increase in height, however I had not read the general statement you made about rubi suspension being 2 inches taller. I have a JKU sport and a coworker has a JKU rubi. Both 2012 models purchased at the same time. Other than red colored shocks, I do not see any difference in height.

 

The non rubis I have parked next to were maybe a half inch shorter if that. I have a JKU. That was mostly due to tire size I would say. As my jeep got older, I noticed that the non rubis that were newer were about the same size.

 

I know you mentioned no lift/ big tires...yet.

Here is an image of the Spider Web Shade JK on a lift and tires BUT no lockers and stock gearing.
I was blown away by what Chris did, this was on Drop Kick out at Area BFE in Moab, not exactly easy stuff.

 

I have a 2008 stock SportU with the "S" package, which in '08 included 17" wheels, the Rubi suspension, Dana 44 axle w/locking rear diff, e-sway bar and a lot of skid plates. The dealer had added a Mopar front bumper and Mopar 9000 lb winch as options. That's how I drove it off the show room floor. (It had the standard Dana 30 open front axle and 3.73 R&Ps) Final crawl ratio was/is about 40:1.

I didn't change much over the past four years:
- I spend a lot of time in the Anza Borrego Desert, so I had the top painted "stone white" which matches the body and keeps the inside about 30 degrees cooler. I also added a Hot Head roof insulation kit.
- The most costly change I made, the day after I bought it, was to change out the stock tires for Goodyear Silent Armor tires. These are the best AT tires I have ever run. They have two steel bands and one Kevlar band. I air them down to 15-20 psi
and I have never had a problem. They are excellent on road, silent running, excellent gas mileage. They are also top rated for ice and snow duty. Off road they are good in sand and mild rock duty. They suck in mud. I have 30K miles on them and they still look good. I highly recommend these tires. In the stock 17" size they run about $175 per tire, but I have seen the cheaper on sale.
- The e-sway bar failed, out of warranty, and Jeep wanted $2K to replace it. I installed the EVO manual system for about $100.
- I also added a Day Star leveling kit. Looks good, no ground clearance increase.

I have been to Moab, Arch Canyon, up to 13,411' on a trail between Ouray and Telluride, CO. and I run the desert trails almost every week. Bottom line: you will be able to keep up with the Rubicons in most trail situations except rock crawling, deep mud and really steep inclines. Their locking Dana 44s and
73:1 crawl ratio make a big difference in these situations.

Like most things in life, it's all a function of money. The more you have, the more you can do.

 

They are a blast in deep mud or snow. They throw shit everywhere!! Close the windows! I never had a flat on them either. The Goodyear sra were a different story. I was always changing flats.

 

I would check out this review, LINK-->2012 Jeep Wrangler Sport [w/videos] it is really good and shows the stock Sport offroad with video

This is a picture from the review so you can tell if you have already seen it

 

One of my favorite threads on the site: Stock JK's in action.

 

One thing to mention - stock JK Rubicons are very close to the same height as Saharas and Sports. The TJ Rubicons were the ones that had a little extra height to the suspension.

 

You would be surprised just how much you can do with that stock sport!!! Just go and find out for yourself you would be amazed, just watch out for the deep water you will be fine, just don't wheel alone!

 

Received some excellent advice on my first offroad experience "Your Jeep is more capable than you are". This stood true for me, every time I thought threre was no way we would make it, we did. Keep in mind that mine is bone stock aside from 33" tires.
