Locker

[medic2967]

My little brother said that 2007-current silverado and sierras come from the factory with a rear locker. Is this true?

[bstill]

RPO G80. My 99 and 08 have it.

It's a limited slip although I think it should be called a limited STICK cuz it only sticks about 1/4 of the time to me it's more aggravating than beneficial that's why I'm ordering 4.10s and a true-trac

It's optional but most dealers order it. GM uses Eaton posi units

its not a true limited slip.

the carrier referrred to the g80 in the trucks is the gov lok. its a centrical weight that locks the rear then unlocks it as revolutions rise. its meant to be locked in a straight line and on equal surface for both wheels. its much better then a truck limited slip. fo what it was intended for its does well

It just can't take that much abuse.

[George C]

just depends on the "abuse" my stock g80 lasted 49k worth of abuse but i wasnt an idiot doing doughnuts or trying to spin tire on unequal ground. when mine finally did go the clutch pack just wore out

Mine's held together, just doesn't function.
