Stock JK 2011 and just want to add a 2inch OME suspension without changing other parts. Do I go with the HD or the Light duty and do I need new track bars with either? Will other changes need to be done? Thanks!

 

Additional components are a preference. If you can put up with the handling, you can run a 6+ inch lift on stock arms and trackbars. Will you enjoy driving it? I doubt it, but I'm not you.

So,
expect 2.25 - 2.5" from the LD's
expect 3 - 3.5" from the HD's
If you go with 4door HD's, expect around 4"

As you go higher, you are more likely to want to add components. Again, it is a 'want', not a 'need'. No one can tell you what your tolerance is going to be.

My opinion:
With HD's, you should consider -
recentering at least the rear axle
getting some form of caster correction
Adding longer rear links and moving the stock rears up front
Adding 2" front bumpstops with the lift. (the rears you can add at any time.)
$10 at the hardware store will set you up with rear brake line ext brackets.
* keep an eye on the tcase ends of both shafts, and think about pinion angles if/when you go to a double cardan.

With LD's - go drive and enjoy
The downside is that they do not handle extra weight. Expect them to sag, especially if you swap from soft to hard top, or add bumpers/winch/carrier/armor.

 

Thank you so much! I think I will stick with buying the LD even though I do have the freedom top! I'm not changing the bumpers so I think I should be fine. Thanks again for the info. Helps out greatly!

 

I am still mid process with my OME lift. But over a year of screwing around here is what I have found:

With a all stock Unlimited.
Front light OME springs (616): 2 3/4"
Rear light OME springs (617): 2"
This set up gave me a level jeep.

I then added a Smittybuilt XRC Stubby and a Warn M8000.
Front light OME springs (616): 2"
Rear light OME springs (617): 2"

Next I upgraded the front springs to HD.
Front hd OME springs (619): 2 3/4"
Rear light OME springs (617): 2"
Again I am basically at a level ride.

I have the rear HD springs, but I still have not put them in. I will wait another month or so, when I put my roof rack back on.

The whole time I have had rear adjustable sway bar links, front quick disconnects for the sway bar, front and rear adjustable track bars, front lower control arms, front and rear bump stop extensions.

If you get the light duty springs you have to get adjustable rear sway bar links. The stock rear links can be moved up to the front. I would recommend that you get adjustable track bars for both front and rear, mine needed them. Also front lower control arms do make the steering less flightly, so I recommend them. However front lower control arms are only a priority after you get adjustable front and rear track bars.

My advice would be similar to nthinuf's post. If you do not want to add anything else and you do not plan on carrying a lot of extra weight get the light springs. The light springs ride great. The heavy duty springs are definetly stiffer. If you have further plans for your jeep get the heavy duty springs.

 

i went with the LD and nitrocharger sport shocks. I have 35s and the jeep handles better than stock. No bumpers or winches added. I wiil buy front and rear adjustable trackbars as soon as i can afford it. Procced with LD and you will not regret it.

 

So the track bar is recommended even with the light duty?

 

i drive my jeep now with the stock trackbars and the LD lift. But being anal about my jeep i think adjustable trackbars will be my next suspension mod. But it is somethink extra.

 

Not sure why this is a 'priority'...I have run LD springs for a year and a half with JKS adjustable track bars front and rear, and have had no issues...maybe if I put on front lower adjustable control arms, I would see a difference, just have not seen the need.

OP, I have a Shrockworks stubby front bumper and a Expedition One rear bumper and tire carrier, and the LD springs have been up to the task, and ride great still.

 

Sounds good. I'm going to buy this throught Northridge 4x4 cause they have a package with the trackbars for 8something! Think I should be fine then. Thanks guys for your time and patience.

 

As I stated the LCA are not needed, but are next on the list of mods after adjustable track bars. Adjusting the caster makes a big difference in the feel. I have run them at 8% and 4.5% (I am at about 5.5% now) and the feeling of stability is really great at 8% while 4.5% is much more flightly/jumpy feeling. If you don't notice or care about the feeling of your steering control then don't worry about LCA.
