In what vehicle?? Makes a world of difference.....
If you mean your truck, the aam 11.5 it came with is a tough piece. Not light, but with it being in a 3/4 ton truck, it has to be heavy enough to take the abuse.

The factory dodge "posi" for the aam axle is a very good choice. It's a different deign than the gm and seems to hold up a lot better. The grizzly locker is another popular choice
I love the grizzly locker. But I bet with a pretty standard daily driver you'd be fine with the torsion gear posi from dodge/Eaton
For our trucks.
I'm running the same unit that comes in the the Dodge, is in one running a locker in the back for Drag Racing?
So lockers/posi then....
Spool.....f**k drivability :rofl:
Just the opposite, I love the drivability with posi!
I'm sure they do with 4wd launches, but I'd say it's not the G80 helping them much with the launch. Long ago I tried everything I could to get a decent launch with the G80 and nothing really ended up working well.
No idea, but it is a CC/SB with no weight reduction. I would guess somewhere in the neighborhood of 7k lbs.
Josh, would you mind finding out what he is running for tires and rims specifically?
He has to be careful how hard he launches or he spins like mad too. He also had better results by putting more air in the tires. I think he's running 22 or so PSI. Weird, I know. He doesn't get to the 1/4 very often, but the 1/8 mile track down the road from him usually preps the track well. His best so far has been a 7.6 with low 90 trap speeds.
I can't wait to start "messing" with the chassis. So far my best 60 has been 1.968 and I constantly trap 99 in the 1/8. I've got to get those 60's down.
