I'm wondering what all i will have to change to put 4.88 gears in a d30 with 3.21s

 

Gears, carriers, over haul kits.

And a stack of cash for an install.

 

Where can I find the carriers

 

Ordered mine from northridge... Probably buying a new axle. Matter a fact I'm will probably be selling everything you need really soon. Including black arb covers. 4.88s overhaul kits, and carrier with spider gears.

 

If you don't mind me asking how much was all that

 

Bump. .

 

I had same set up. I bought the gears and carriers from Northridge and had a local shop install gears plus sleeved axle and welded gussetts. Total cost $1150 parts and labor.

 

I ordered a lot at once so my bill was like 1400 but like I said I decided to do an axle upgrade so not installing the gears. If you install a locker in the front you don't need a new carrier but research it because there are cons to cheap lockers especially in a D30

 

What are your ultimate goals, tire size, wheeling hard? Or are you just wanting more power in your DD?
