I'm sure this has been discussed. I need to pick one. Dana 60 with 35-spl axles. This will be a street driver, probably a 400-451 and manual trans deal. I'm going to fit the car with two sets of tires, one set will be the old Mickey Thompson N50-15 and the other set will be Nitto 325-50-15, 555r .
I guess I just need a push to either go with a clutch posi or the locker, not sure if I actually have a preference for a street car. I went with the cheap, simple and no moving parts option: A spool!

I am using the clutch type in my Dana 60 with 35 spline axles for street / strip use . So far it's been great for both.

Locker. Hands down every time.

If I remember right the locker was developed to make the outside wheel power in a turn whereas on an open or posi rear the inside wheel is always under power, the outside wheel is always trying to catch up. They didn’t use posi units in NASCAR for that reason. Ford developed the locker to utilize the advantage to make both wheels have equal power going around curves.

Using a Detroit locker here in the Challenger, Dana 60, we've had no issues, fitted in 2014 IIRC. I can't hear it make a noise, (over the exhaust note anyway). And it doesn't feel "clunky" at all. I read a lot of stuff on here saying it would be horrible, noisy etc but in all honesty it has been fine and doesn't feel any different to the 4 pinion power lock that it replaced. Now a friend has a locker in a Cougar with a 9", behind a 347 and a five speed. That was fitted about 20 years ago and it is noisy. I'm wondering if the newer ones a different design?

Had everything at one time or another, and everything has its purpose. But the one thing i didn't like, and will never use again, is a Detroit locker. Thing was downright creepy when you got out of the gas at speed on the street. Squirrelly. Almost unpredictable sometimes. No thanks. Spool, sure grip, cone or clutch.. fine.
