Open Diff's

[shakazulu12]

Oh yes, I'm aware of the functionality of the ABS based system. However its been my experience that nothing replaces a good old fashioned coupling, it seems to me that its kind of in-efficient to use an ABS based system with open diffs, because you are consuming engine power and torque by using the brakes to move power around. I have driven a Sierra Denali in all kinds of mud and bad situations, and it pulls grip out of nowhere it seems (uses a viscous coupling, not sure why this model does when most GM vehicles don't, not even the regular Denali SUV), where ABS based systems still feel a little hesitant to put power down, I have no experience with the H2 system yet, but it was just an observation.

Does anyone make an aftermarket LSD or something?
