How high can I lift my 2009 Rubicon 2 door without having to do drive line modifications?

also what type of load rating should my coils have?

Notes:

(I have a steel bumper with a winch on the front and a modified smitty built tire carrier on the back that it causing my rear end to drop)

I really hate it when the back sags down. when my Gerry can is full and i carry a few extra pounds the back the suspension is almost bottomed out with a rubicon express 2" spacer lift.

 

Search function, just kidding.

With a 2 door you are lookin' at 2 1/2" suspension max with out a new rear DS. You can run stock rear with 3 1/2" but in less that 10K the CV joint will go out.

I have 3 1/2" rubicon exress and am running the stock front and it is right at the limit FYI. The jump in money from a 2 1/2" to the next step is huge, if done correctly.

 

if its a true 2.5" lift, if the actual height is over 3", you'll need the additional parts.

Stick to a 2" lift to be safe

 

Well, I have a 2DR and 3.25" up front (TF BB and TF 3/4" spacer above it). 2.5" TF BB in the rear. Been running them for about 30,000 miles without an issue and wheel it every month for close to 2 years now, and hard at that. Stock drivelines, no issues, joints and boots intact.

 

I am running ft 3" lift with 3/4" spacer up front... Been on for like 12,500 miles and no problems yet... Stock drive lines...

 

I spoke to a TeraFlex rep and a local 4WD shop, and they all told me I don't need to upgrade my drive shafts with the TeraFlex 3" lift kit. And on the 2 door soft top, that's going to be about a 4" lift. Again, this information was from the experts.

 

Ask them if they'll pay for the new driveshafts when they rip apart, they are giving you a line of BS.

 

you and usgone are the exceptions to the rule, he's running a 3" FT lift and no issues yet either.

here's a quote from today in another thread

Did you extend your bump stops? if not you'll over compress the coils flexing out.

 

unfortunately, whoever you talked to doesn't know what the hell they are talking about. personally, i would steer clear of the 4WD shop you talked to and someone at TF should be told that their reps are giving out bad info.

 

A TeraFlex 3" on a 2dr (makes for a 5" kit), definitely new shafts front and rear. Adding adjustable control arms is highly suggested. On a 4dr at least the front with a auto, but count on the rear some day.
