I had one of those Powertrax lockers in another truck. It was fine, but this time I figure I can do without the clanging and banging. Just straight tire eating. A mini spool is cheaper, too.

One approach is to use the B-O-P 8.6 w/o the C-Clips as a small drag car rear end. Spools readily available, and a bunch stronger than the Chevy version
Still an 10-Bolt. Many rears will swap over directly, housing and all.
Or, go to Redline Explosion Proof and it'll live for a while. But you may still spit out an axle when a clip goes
It's not exactly a race truck. The 4.3 might put down 120 HP on a good day. It is more of a utilitarian thing. I do some work out in the woods, and I never ever want to get stuck out there. Sure, it's 4WD, but more is better. Zero cares about handling on pavement or tire wear. It needs to pull trees up muddy hills.
Would it be crazy to install a 3-point hitch and drag a box blade with this truck?
So, Redline Explosion Proof is the gear oil I should use.
