Not to cause any issues, but, I've had that lift on with 37s since April'ish with stock driveshafts and I check them often. No problems here. Not one vibration. I have an auto tranny & it's a 4 door by the way. I figured I'd leave the stock ones to see if I had any problems come up. And it's all good.

 

soo ... what does that mean? Does that mean I am getting screwed? I don't think I was ... he gave me a bunch of discounts and is chargine me less time that it will actually take.

Hmm .... well it was rubicon express that actually called him. I am going to call them in the morning I think, just to double check.

 

Could be a good idea. I know Burnsville Offroad, a sponsor here, was running stock driveshafts on some of there Hemi powered JK's with that lift on with no problems. I called them before I put my lift on and that's what they told me. Maybe give them a call tomorrow to see if anything has changed for them.

Offroad Evolution may know a thing or two about this as well. I am no "expert."

 

No with that kinda lift, you probley will need new driveshafts eventually anyhow. They sound like they know what they are doing.

 

Torque converter.

 

I know that in the instruction from Rubicon Express they say you need to replace the drive shafts. I am sure on the 4 door you would be fine for a while, but it is just a matter of time before they will need to be replaced.

 

Hey jkgirl08, I tend to agree with Piginajeep and what your shop is saying especially if you intend to go wheeling. I'm running factory drive lines on my JK with 4" of lift and 37's now and can tell you that while it does kind of work, you'd be better off with a new set of shafts. If you have an auto and pull your auto skid plate, you will still most likely ruin your front drive shaft boot as it makes contact with your exhaust crossover when flexing. Plus, at this height, your rear shaft will be at a steeper angle and this will cause your CV boots to wear out prematurely. Need I say, I think your shop is just looking out for your best interest and not trying to screw you in the least.

 

Yeah .. I don't think they are either .. just doing every thing at once .. what would you say for regearing.

SHould I go up to 4.56's or 4.88s?

 

another question ... do I regear before I get my lift put on???

 

You can always do it at a later time if you don't want to, or can't afford to do it all at once. I know that tehre are lots of people that tend to do this towards the end of priority list when upgrading.
