My buddy is selling me axles with 5.13 gears and ARB Lockers.

I have a D30 (infront) & D44 (rear)

*Do I in this situation need to get a new driveshaft with this set up or is stock ok to use.
If I do need a new one, why is that the case?

 

We my jeep has a 2.5 OME lift, u think it will be affected?

 

You will need new driveshafts because of the lift height, shock length, model, transmission type, axle centering, type of use, etc. Not because of your choice of gears/lockers.

Higher (numerically) gears will have your driveshafts spinning faster, though, so it may be more noticeable if you have balance issues with your current shafts.

 

I have had a 2.5 lift and 35 for about a year now and no problems. I was wondering about the drive shaft due to lockers and gears. So lockers and gears have absolutely nothing to do with the driveshaft. Is that what u r telling me?

 

I have a 2010 auto unlimited D30 on front and D44 on back

 

you should look into replacing the driveshafts at some point anyway, the stock one's are pretty weak. Also make sure you notch the skid underneath the front one with that lift, it's usually the one that takes a knock at full flex. it's a small cut that gives it about an extra inch or so of clearance and peace of mind. I didn't do this....which lead to new shafts.

 

The lift height has your driveshafts operating at steeper angles. Since you have an unlimited, the rear shaft should not be affected. But you might want to keep an eye on the front shaft. With an auto, it is likely to contact the crossmember skid and the corner of the tranny pan when flexed. There are some preventative steps you can take, but losing that boot isn't a huge issue. Just make sure that you are not smacking it hard enough to damage the tranny pan. The bigger issue to watch for is grease spitting out of the joint at the tcase. It is easy to spot, as there will be a ring of grease on the undercarriage above the joint. Lift height, shock length, flexing, etc will determine how long that boot lasts.

But no, other than speeding up the driveshaft rotation, the new gears should not affect the need to replace shafts.
