Talking with my dad the other night about his first muscle car. When he was 18 he bought a brand new 1966 Dodge Charger with a 383 automatic. Pretty rare car, only 13,000 made. He said one of the options he bought was Posi-trak, which he explained as both wheels spinning at the same time, opposed to one at a time which was the norm for the day. Is Posi-trak something that is still around today? Or has "limited-slip" replaced it as the new modern version? What do our L's have?

Same thing.

Same thing, different name.

For simplicitys sake, all it means is that you get power to BOTH wheels while going strait ahead. It also acts like an "open" type differential and allows for "slip" while going around corners so that your inside wheel doesn't hop like it would if it was a "locker" or "spool" type rear differential.

 

The other day i was looking at the window sticker (the red one that comes on the
passenger window.)It lists all the standard
& optional stuff. It had "Traction-Lock"
instead of "Limited-Slip" rearend. I thought
Ford always called it "Limited-Slip".

Don't quote me on this, but I think it is

Ford - trac lok
Chevy - limited slip
Chrysler - posi

 

AMC - Twin-Grip

 

Howdy!

Question to all:
Why limited slip other than for cornering purposes? Why not get traction to both wheels? When I step on the gas with my F-150, all I hear is a lot of screeching on my right tire and not much else. I'm also going nowhere really fast. (While the Chevys and Dodges take off) This really blows!

LeanNCut,
I don't think you quite understand. Posi, limited slip, traclok.... whatever you may call it. They all give equal power to BOTH wheels when your vehicle is pointing STRAIT ahead. When you go around corners, the clutch plates in the differential "slip" thus allowing you to turn the corner without the inside wheel "chattering"
If you are only spinning one wheel when your pointing strait ahead, you DON'T have a posi/limited slip,traclok or whatever. All you got is what is refered to as an "open"or "standard" differential.
Another thing, clutches can wear out after alot of miles. In that case the posi/limited slip or traclok can act like a standard diff.
They are however, fully rebuildable... unless your talking about the old GM "cone style" limited slip.

 

Lightfootning is correct as far as i know. The odd thing is that the same oem manufacturer has made the parts for the different companies at the same time. They either have a little difference in design or the sticker on the box is the only difference.
