Thanks for the comps gentlemen. I know that I will have a competitive ride, but I know I will never reach the stamina that most trucks have now like a turbo or the juice. I'd like to learn what the truck can do without making an experiment out of it. I try and keep it conservative since I have a house note like many to take care of.

Here is a shot of the new guts going it.
Now to get technical:
The ring gear bolts are a left hand thread and require a 3/4 inch socket. The torque spec for them is 65 ft.lbs. There are 10 of them, and they need to be tightened in a criss-cross pattern.

Question from the novice...what is that gold stuff in the gears? Or is that just glare?

Alright, before stabbing everything in, I had to check and double check the pinion shim thickness. Since I have done 4.10s MANY times, I know that .035" to .037" shim works.
Once the pinion is in, I install the differential and check the backlash. The specs for these gears is 6-10 thousanths. This one hit right at 7 thousanths.
