Wouldn't that be intelligent after dropping that much coin on all the parts?
Personally I prefer to leave the factory depth on the pinion. I feel that the chance of human error causes more of a risk for a failure, then leaving the depth the same, and just adding new bearings with races on the carrier.
I have around 30-35K miles on my 00 truck this way with some towing, heavy foot driving, and sled pulling with no issues.
I helped a friend of mine put one in his 97 this way and hes got well over 100K on it. The only way to describe his towing and driving habits would be retarded :doh: On an otherwise complete factory 300K+ axle.
After I installed the one in my 08 truck it saw a sled pull, and more leaving black marks then actually moving forward the first 100 or so miles.
I am not trying to say to do it one way over another just sharing my experiences this way.
