Which posi unit do you like?

[Old Guy Bill]

The posi units with spring loaded clutches always work well on the street, we used to have to use an additive with those before synthetic lubricants. They will hold up fine unless you’re using slicks.
A locker will be radical on the street, it’s really for race applications.
I’ve got TruTracs installed front and rear, hope to get to use them soon.
