Whatever you say, fella. It's fairly common knowledge I thought. If you can prove me wrong, I'll eat my hat.

Don't worry ill get a pic next time I'm at pops for you

My vote is a sf 14 bolt or it's a Spicer axle.
Definitely intrigued.

Wow!.... so many posts on this thread have bad info or bad typos.... ... C'mon man !
....

My 81 k20 has a 14 bolt semi float with a locker that has always worked great

This thread is epic! Both entertaining and disappointing. A Mad Ogre proclaiming he's not stupid and a whole thread on axles without one instance of misspelling axle! Ogre hasn't been seen since Oct 2015. I think your hat is safe bucket.

I didnt see this was a old 2014 thread

It was in the "whats new" section

This actually wasn't the only thread where we disagreed about rear axles. In the other thread, he insisted that the 6-lug semi-float 14 bolt axles were used in the gmt 800 trucks and I said they weren't. Well, a few years went by and one day I saw one of those really rare "Vortec Max" trucks and then it hit me... that SOB was right! The Vortec Max trucks seem to be rare as hen's teeth but I'm guessing the Silverado SS used the same axle.

To this day, I haven't figured out what thread it was so I could own up to being wrong and he hasn't been here so I could tell him he was right.

That's interesting because I don't know much about the Vortec Max trucks that you say are rare. I have seen quite a few of them, I know exactly what you mean. But, living 5 miles from Mexico, I see a lot of oddball models from all the OEM's that make me look twice. And usually, they all have Sonora or Baja Mexico plates on them. That might be the case with those trucks.

Really? I think I've seen only two of them. I remember a magazine ad for them, but it was probably 2018 before I saw one (which made me think of the thread). Then a year or so later, I saw another. It was a pretty cool package honestly.

Lol, I forgot about that one too!

He seemed like a pretty decent guy, which is why it bothers me that I was wrong about the other one, but can't tell him.

I never heard of him. Maybe before my time. I'm still wondering about Honky Kong Jr. Anybody remember him?

Mad Ogre and a few others went away after some fiasco. There were about 4 or 5 members that bowed out at that time. I forget what happened, just that it pi$$ed them off and they left. Donkey d0ng, he just slowly faded away.

So I was curious about the Vortec Max trucks and did some googling. Apparently there were different packages. So here's what I learned:

The gmt 800 trucks with the Vortec Max option got the LQ9 (essentially, possibly the very same thing... I didn't research), a 4L70 trans and the 14 bolt axle, although with drum brakes. Beyond that, there was the 4x4 version that had a trailering package with ride control, 17 inch wheels, a gov-loc and 4:10 gears. That's the one I remember in the magazine ad. It also could not be combined with the Z71 option. But there was also a 2wd version with a performance suspension and 20 inch wheels. From what I gather, it was basically a poor man's Silverado SS.

For the gmt900 trucks, the Vortec Max emblems on the doors just meant it had the LQ9 under the hood. The trailering package with the 14 bolt was a separate option. It also could be combined with the Z71 option.
