Maybe I will search out an 8.25 then, just keep it simple 8.25 & 3.9:1 then I can add LSD or a locker later on. This is completely street use so I'm not sure if a locker is really going to help unless it's a drag strip.

 

your looking at the same use as me, i've ben recommended the powertrax no-slip lsd by a couple other users that have them, basically what i'm going to go with when i get to it

 

Is the powertrax no-slip suppose to be some sort of ratio closer to 40:60 or something? It can't be both limited slip AND no slip?

I need something that will lay a double strip, and as equal as possible when laying around a bend/corner. My 7.25 open rear end and crappy 3-speed is pathetic, it gets one wheel going good around corners from a standstill...by the time it hits second the rpms peak though hah

 

The Powertrax No-Slip is a full locker 50/50 it just has a little extra mechanism to "Help with turns on pavement"

 

huh...i was told that was an lsd O_o so by mechanism that would be the racheting effect on turns?

 

I'm very curious now, I did not realize any full locker was able to take turns on pavement. What Dakota and Durango packages would this be in? Is the axle built for/recommended for street use?

 

Spools suck on the street, but lockers are ok. I had a Detroit locker in a Chevy truck that I used to own. I drove that thing for years with no problems. It used to bang and clunk once in a while, but it was pretty much indestructible. Didn't really cause any tire wear problems or anything, either.

 

No lockers were available from factory. Only aftermarket. LSD (which are junk in my opinion) was a factory option.

Automatic lockers unlock for turns when your foot is off of the throttle, it locks back up when you get on the throttle.

Selectable lockers act like open diffs when not locked/engaged then is like spool no unlocking until deactivated.

A spool is always locked. Never can unlock.

 

Looks like a Powertrax/Detroit can be had for $500 would that be considered an auto-locker?

 

I agree that the factory option lsd is a POS, but I disagree that they all are. I've had good luck with Auburns in several vehicles, and I like the Yukon Duragrip I'm running now.
