I bought a suburban that has differential lock. The original sticker
Locking Differential-rear axle
I'm wondering how this works (ie wheel slip, electronic lock) he only
paid $252 extra. It doesn't have 4x4 in it so I'm wondering how well
this works as I have some pretty steep grades I'd like to try it on -
15-20% with gravel. I've got an old GMC 4x4 that pulls myboats up this
grade with ease and I'm wondering if differential lock will make a
difference under these conditions and allow me to at least get the truck
up the hill or what conditions the differential lock is intended for?
Thanks in advance!!

Yea, but doesnt GM use the centrifigal locker? Where the wheel needs to
spin up to a certain rpm
be fore it locks.
Look at your option codes for "G80." If you know how much he paid, I'm
guessing you have the original window sticker, so it should be easy to
find otherwise, you can look for a sticker in the glove box or a plate
on the firewall. If you have that code listed you have an Eaton G80
locking rear differential. There is a lot of information available on
the net, but basically, it is a mechanical system which will lock the
2 axle shafts together when there is a 100 rpm difference between the
2 rear wheels and you are traveling at less than 25 MPH with stock
