I'm about to order gears for my 09 sahara from northridge. I have 3.21s in it now and have just over 4000 miles. Can I get the Install kit or do I have to get the Overall kit. BTW im getting 4.88s b/c i have 35's and am not going any bigger its a DD. Thanks for the help

 

you are gonna need new carrier as well

 

It sounds like you can save time on the install by going with the new bearings and the risk of having to do it over again is reduced. But, it comes down to how skillfully the old bearings can be removed.

 

what he said. being that you have 3.21's, you will need to get a new carrier and i would recommend that you get the overhaul kit.

 

If you have an auto, you'll regret the 4.88's.

 

I have a 6 sp. what is the carrier that you guys are talking about
