i don't really buy into the whole extra clutches thing 100% my buddy in h/s worked for a shop and his boss was into building 4x4's. he had the boss set up a f/r trac-lock set with extra clutches and 4.56's for his 78 bronco, and it really didn't seem like he gained anything from the extra clutches. maybe you know what you are doing better than his boss, but that guy had some sick mud trucks, but he was a chevy guy. i don't know what posi's they come with stock, but i saw his k30 on 40'' boggers rip off all 4 tires on pavement trying to get his tow truck unstuck. he told me that the axles had 5.13's and factory posi's. what do chevy's use for limited slips?
What I did was ditched the spring plate, and added as much friction plates and drive plates as I could. There was no turning the spiders in by hand, I had to use the starter with the trans in 1st and the tcase in low. with the parking brake set, and the hubs held in place with ratchet straps.
The chevy stuff could be a power lock, or a gov lock if I remember right.
[QUOTE=nighthawk285;9065243]ok, what's the difference between a power-lock and a trac-lock. I was able to get a trac-lock carrier to work with the 4.10s for $50 (local j-yard owner is good friend) and I want to re-do the clutches before I put it in....I've heard of people adding a few extra clutches to get more hookup, so I'm looking at these
