As long as you just want no more than 4.10 gears, you can get them at Dodgeparts.com for not too bad a price, and they are stock Zf gear set. I do not know if the locker is different. That is what I got!
If you change out the rear you have to do the front gears. Dodge decided to weld the front gear/pinion to the carrier and it requires you change out the whole front end to a 2010 front end. I just had an LSD installed last week, would have done the gears too if it were possible.
did they weld the ring gear to the carrier in 2011? i have an 08 and i was looking to do a gear swap to 4.56 when i get my suspension lift and 37s. does this affect 2010 and down?
