Posi Unit

HemiBabe · Feb 6, 2011

I want to upgrade the rear axle from the Limited Slip to a Posi, anyone know where I can go to get a posi unit for my truck?

It's the 9.25 10 bolt LSD right now

Thanks in advance

you have a 9.25" 12 bolt rear. Like Nick said, Auburn or Detroit Tru Trac are the 2 most popular

just FYI, posi is a limited slip. Posi-trac is GM's term, like our truck OEM LSD is an "Anti-spin Diff"

Here are some common OEM LSD names:

# American Motors: Twin-Grip
# Buick: Positive Traction
# Chevrolet/GMC trucks (after 1973): Gov-Lock
# Chrysler: Sure Grip
# Dana Corporation:Trak-Lok or Powr-Lok
# Ford: Equa-Lock and Traction-Lok
# International: Trak-Lok or Powr-Lok
# Jeep: Trac-Lok (clutch-type mechanical), Tru-Lok (gear-type mechanical), and Vari-Lok (gerotor pump)
# Oldsmobile: Anti-Spin
# Pontiac: Safe-T-Track
