Locking Differential versus Limited Slip differential
I have a 2004 Silverado 2 wheel drive ext. cab. I'm wondering what the difference is between a locking differential and a limited slip differential. My truck has the locking differential (RPO code G80 - locking differential heavy duty)?
I noted I have very good traction for winter driving here in Wisconsin with my 2wd and my 20 inch Goodyear tires. Are there disadvantages to the locking versus limited slip units?

Re: Locking Differential versus Limited Slip differential
There's no difference that I am aware of. The terms locking, closed, limited slip, and positraction are used interchangeably AFAIK

I think I read on the Eaton site that the Limited Slip is activated via input from the drive shaft and the Locking is via loss of traction on one side or the other. Again "I think".

Re: Locking Differential versus Limited Slip differential
limited slip has clutches in it, and requires a "limited slip" lub additive. The "locking" rear is quite different and does just as it's name implies--it locks--no clutches! They also use "g80" for the 2500hd duramax I had, and that rear is four times the "g80" in a half ton!

Re: Locking Differential versus Limited Slip differential
Better traction comes in different forms. Straight off the line WOT open diff will spin for a while and takes less power/friction to run. The positrac allows slip but has to sense slip before engaging. The locker pretty much is both sides are engaged at all times thus taking up more power, minimal as it is but at an instants notice will keep the rear stable. The locker will allow some slip around corners but very little, very. As tought to me by teacher(master) who races.

Re: Locking Differential versus Limited Slip differential
Nope, not that annoyed. That crap is awesome in the rain about not losing traction, White Lightening knows...

Re: Locking Differential versus Limited Slip differential
Actually, on my breakdown of RPO codes, G80 reads "Axle Positraction Limited Slip"

My guess is that GM's version is just another name for limited slip, not a true locker. |

Re: Locking Differential versus Limited Slip differential
No clutches on a true "locker". They use metal teeth that mesh together--locked. The only way they can slip is when the teeth basically skip a cog (causing the BANG!). This should help:
