Upgrade from stock sport shocks to rubicon shocks.

I was wondering if I should upgrade my 2008 2 door jk from its factory shocks to the rubicon factory shocks. Will I notice a difference in the ride at all? Is there anything extra I have to add since my jk is not a rubicon? Just curious, this is my 1st jeep just wanting to upgrade but not to familiar with jeeps. Thanks

May be a bit stiffer. You'd need Rubicon springs as well to gain any lift.

So I will actually get a lift if I use rubicon springs too? How much of a lift? And are the rubicon shocks just stiffer than the sport?

Lot of false info in this thread, for example, THERE IN NO SUCH THING AS RUBI SPRINGS. All wrangler springs come with part numbers 19front 60 rear are the stiffest/largest but they vary to 18-59 17-58 16-57 56....all depending on things that have nothing to do with a rubicon/sport/Sahara model name. Unlimiteds with max tow and hardtop usually get the stiffer springs but it really is just mostly luck of the draw on what numbers you get. I've seen rubis with the lowest numbered springs, while my base sport unlimited had 17-58. Unless the springs are off a 10th anniversary edition (came stock with a little larger spring for a little more lift), there is no extra lift just because they are off a rubicon.

What would I expect from these kind of coils then Front coil # 52126314ac / Rear coil # 68004257aa? What would the stiffness for these?

Last two numbers of each 14-57 not very good at all, higher the number=more stiff you want 19-60 18-59. Don't waste your money on takeoffs, blow the extra few hundred and get a real lift. The gain from takeoffs will be minimal if anything, check your spring numbers now, you might have higher than those already.

What would be my most bang for the buck then? I don't wanna go no more than 3inch lift. But I don't want crap either

The most bang for the buck WOULD be doing a Mopar coil spring swap. By definition, it is a "real lift." Went from 14/56s to 18/59 and rubicon shocks for $140 new. If to do differently, OME light springs and nitro shocks, would get the nod.

TF1352000 Teraflex 2.5" coil lift with shock adaptors. Uses stock shocks (or the rubicon shocks if you'd like) and is a complete kit, won't need anything else but wheel spacers of you use your stock wheels. I'm still on stock wheels an tires and stock sport shocks. Rides great and looks awesome, just need some bigger tires and I'm set. Probably all in for $550-600. Message forum sponsors who sell the kit and you will get a good deal, got mine shipped for $50 less than the retail price (on quadratec, other stores) think I paid ) $439 for lift and 125$ for spacers.

Another. Also sits very level and I am confident it won't sag with any weight added to the front (bumper/winch)

You should get best Bang/Buck by picking up JK OEM take-off springs. My research suggests that you get about 0.5" lift / digit increase on front shocks....while back shock upgrades (less lift / digit increase and less consistent results) give about 0.2 to 0.4" / digit increase. This assumes no other changes are introduced into the equation. Both the 4-dr & hard-top options have more impact on rear springs. Subject ratios include input from Jeep Service & Re-build shop folks. The JK OEM shocks should work with such a spring lifts up to 2". This is the approach I'm taking with my 2013 Sport 2-dr.

I just bought 2013 10th Anniversary 2 Door Rubicon shocks and springs. Would these fit my 2012 JK Sport without any problems? Do I need to get anything else to make it fit? Thanks!

They'll fit and provide a slight lift...best to have the Jeep aligned after install. Can probably swap springs and shocks in your driveway in about 2 hours with a buddy if neither of you have worked on a Jeep but can twist a wrench. Floor jack, jack stands, 18mm and 16mm wrenches and sockets needed...and I forget what size is on top of front shocks. Ratcheting wrenches will save you time and frustration.

Thanks, can I use this instruction? Project-JK.com - Jeep JK Wrangler Resource » Old Man Emu Jeep JK Wrangler 2″ Lift Installation Write-Up. I have one 2 ton aluminum floor jack from Harbor Freight and two 3 ton jack stands. Would this work?

Pretty much. You won't have the OME 1/2" Spring spacers to add and regardless of transmission, shouldn't need to remove any skid plates. You also should not need to remove your track bar. Basically just follow steps for unbolting shocks, swaybar links, wheels, brake lines, etc.

In the long run you might want to consider an adjustable track bar (such as that from JKS), and a better quality steering stabilizer (Such as a Bilstein 5100). I'd take these steps if you get some death wobble, but given that you probably won't see more than 1" of lift, your Jeep should do fine.

Finally got it done by myself took about 4 hours. It looks great, the steering wheel seems to be straight and it feels lighter. Should I have the alignment done?

How much of a lift did you get from this? If any at all? I'm just waiting for the coils and shocks I got from eBay to do this.. Was their any complications?

I forgot to measure, but did take before and after pics. I would say maybe an inch more when I compared the shocks and springs. I also have 10A wheels and tires so it looks much better. There were no complications, just make sure you have the right tools. For the fronts, make sure to free the brake lines by removing the nut, as well as the rears. On the passenger side shock, I'm not sure why there is no access to the top nut so I had to cut the plastic part a little so I can get my tool to it instead of removing the whole plastic piece.

Shocks do not lift..

The only real increase you get from OEM springs is if you get 19/60 18/59 take offs from an Unlimited and put them on a 2dr that has light springs like 13/53. The lift is because the springs are stiffer so be prepared for a stiffer ride. If you want a little comfort in your ride just get a proper lift with all the proper parts to lift and handle properly.. Most guys that do the OEM swap end up changing them out within a year or less. A lot of work for an incremental increase.

I ran the Rubi suspension for about 4 years, and had about 1.75" lift with it. I was building to handle Gator trails at the family farm, which includes several steep creek crossings. If the goal is to clear 33x12.5's and improve clearance a bit, this can be the cheapest and most effective way to do so. I'd say that it's much better money spent than on a budget RC 2 1/2" lift or a spacer lift...and it's definitely better than a mere body lift

There's also a lot to learn from driving your nearly stock Jeep and installing a VERY simple lift like this before blowing the budget up with long arms.

Lastly: YES, get it aligned! Especially if you live in a northern, cold weather climate. Cold temps increase the Jeeps susceptibility to death wobble. An alignment should always be done after lifting, but can also help avoid death wobble.

My 2014 Rubi X came with 18/59 springs and sit taller than my Sahara with 33's on it did....

I'm resurrecting this one. I currently have 13/55 springs. Sunday I'm picking up Rubi shocks and 18/59 springs with sway bar links and front coil spacers (factory). With this increase in numbers, will it be necessary to use the coil spacers, and how much lift should I expect? Would an alignment and straightening the steering wheel be necessary? Any advice is welcome. I'm new to this with a limited budget, hence the reason I'm going in this direction. Thank you very much!

No more rubicon suspension guys. It feels a little stiff sometime. Will upgrade to AEV 2.5" lift soon.

Scott, I very vaguely remember a thread on this fairly recently?...I could be wrong. Maybe one of the guys brought it up on the Willys thread. Did you try searching rubicon springs?

I said "screw it" and just PM'd Daggo66. I know there have been a metric buttload of posts regarding this in the past and I hate rehashing old topics unnecessarily. Daggo is the resident pro on this one, so I decided to go right to the heart of the matter!

JTPhoto JK...above is correct...I did not mean shocks provide lift I meant "springs" provide lift in my 9-14-13 post (sorry if I mislead anyone).

Roger that - would you mind sharing what you learn from Daggo? Would probably be good to place here because I've seen it pop up quite a few times with people looking for a small lift at a reasonable price. I think it even popped up in the Willys thread with some guys with 2 doors looking for 4dr take offs.
