Smile posi question

What other posi/limited slip unit were offered 67-72 in the half tons? Other than clutch style

I have a non- clutch style posi, just cant find any info on it. Not a locker, but has smaller springs.....looks like the internals of a watch, only a bigger scale!! its crazy looking

Any help would be greatly appreciated

Re: posi question

The unit with the "clock works" internals is known as "Gov-loc". Option code G 80, but is was never offered in the 67-72 trucks. This was a 73 and newer thing, but could have been installed into an older truck by some previous owner

Re: posi question

Thanks! Looked up info and images of the GOV LOC and that is exactly what I have. Also reading a lot of horror stories. I suppose a stock to mild 350sb daily driver will be ok for this unit?

Re: posi question

I wouldn't waste the time or money to install one....if it was already there, I might leave it.
They aren't the greatest thing going, but they can survive if driven calmly.

Re: posi question

The Gov-loc is fine. In fact, for it's intended use it excels. There are millions of those units in use.

If you want to drag race or go hard-core off-road with big tires; you might want to look elsewhere.

Re: posi question

Agree with Long Hair. The Gov-Loc (or Gov-Bomb as most of us know it) isn't all that it seems. If it's in a stock rig with a stock engine, you will probably have no worries. But add a little torque to the equasion and it's not a matter of if it will go... it's when.
