Yeah, you'll need a new carrier for 3.73 and up. I just had to buy one for when I swap out to 5.13s from my 3.21s. I bought an Aussie locker too. I cant wait to get this shit put in.

 

Like I was saying before sorry it was soo damn confusing my fault.. I originally had 3.21 gears and when I swapped over to 4.56 I had to pull the front driveshaft axles and gears in the front and cap everything because I didn't want to by a new carrier that would work for the new gears when I knew I was going to be installing a locker in the front. So what I did was I had just Installed the rear gears with the locker in the back and left the front empty for a couple weeks until I could get the locker.

 

This is true although being at the point where I all ready had everything taken apart and out It was just easier to leave it taken apart and cap everything to save time when I did have what I needed for thew final install. So let this be a lesson learned the 3.21 carrier wont work with anything over 3.73

 

Thanks guys. I recieved alot of support and knowledge. Gonna order a new carrier next week and install these 4.10s and while im at it. weld on some gussets for the C's and diff covers.

after this..... hmmm body armor or control arms and drive shafts....
