Limited Slip
Did any of our trucks (or older) come with a Limited Slip in the Sterling 10.25?
I've been looking to get one from a junkyard donor and can't find any. I really don't want to spend the $500 + for a new one.

IIRC Positraction is a GM brand name.
Limited slip is the generic term for traction adding differentials.
If you rear axle is open, a LS will make a huge difference. My '87 dually has one and my '97 SRW doesn't. The '97 barely move in 2wd on ice or snow, while the '87 will go nearly as far in 2wd as the '97 will in 4wd.

I feel like the LS in my truck works much better than my dads 6.blow which is a LS 3.73. Whenever I do a burnout it's two wheels no matter what the road conditions or road angle or whatever. But with his is a crap shoot whether it with be a one wheel peeler or actually be a LS system.

the disc brake rear's are harder on the limited slip during burnouts then the drum brakes are. its easier to overcome their holding force then the disc's. look at a diagram of the internal's of the 10.25 ls and the 10.5 ls. the physical weight alone is ridiculous. i would bet the 10.5 carrier is 30 pounds heavier then the 10.25 carrier and if i recall it has twice the clutches.
and yes, "positraction" is a GM name just like "hemi" belongs to chrysler...... even though ford and chevy have had "hemi" headed engines they are not advertised as such.
the same goes for rear's. they are all "limited slip's". GM calls theirs positraction while dodge's was the sure grip, and ford uses a traction lock.

It might be a draw back for burn outs but launching in 4wd you can now build 20+ PSI boost and still hold it back to launch.....Ask me how I know.....

That is a good point, I like racing as much as doing burnouts. How easy is it to hook up a line lock to the front brakes. Then I would even have to burn up my shoes or eventually pads in the rear

i can still burn both tires in my truck with the disc's via powerbraking but i prefer to save my rubber, its expensive to replace, i spin in the rain and mud and occasionally the snow when we get it. dry pavement is too hard on the tires

is it possible for limited slip rearends to wear out?
in the mud or snow i spin both rears but the few times i've done burnouts on the road
they are one wheel peels. Just curious, i'm not even sure of the code on the axle, and
can't check since truck is still at the shop getting tranny built.
Side Question: What ford engines were ''hemi's?''
