I think I found a GM 6 lug 14 bolt 9.5in out of a 2005 1500 VHO that had been wrecked. They want 1200$ for it and said they were willing to give me a deal on it. Are those worth the money and the effort to put one on?

 

depends on what your plans are... a lot of guys are going deep in the 12's and some brushing 11's on the 10 bolts...

 

I say if ur stickin with a stock or close to tire size, stick with the ol' ten bolter. If ur going with really heavy wheels or bigger tires, and or lots of power go with the 14sf, keep in mind weight is a factor in going fast, and that will ad at least 250lbs.

 

Parish ran like a 10.08 didnt he?

 

Our truck 10 bolt is much better than the cars 10 bolt. Ours has a 8.6" ring gear, while the F-body has a 7.5" ring. Typically, the larger the ring, the more inherent strength it has. I haven't seen many current 10-bolts break. Typically, its the stock G80 that has issues. Upgrading to an eaton or detroit locking diff usually is the cure. I don't think our 10-bolt with upgraded locker will have problems going into the 10s (depending on weight of vehicle). And yes, parish ran 10.0x on the stock rear end.

 

Parish also launched in 4WD.

It is not the ring gear that is the issue, it is the pinion. Together with a small, weak housing, the 10-bolt just wasn't made to be abused.

If you're planning on big power (500HP+), I'd go for the VHO rear. If not, then a nice thick diff cover for your 10-bolt that preloads the carrier (a la T/A style) will be fine.

 

Yes he did (as do I).

How much smaller is our 10-bolt pinion than a typical GM 12-bolt? The ring is within 1/4".

A larger case, thicker axle shafts, stronger bearings, full-floating rear, etc... would be better in terms of strength. But, how many non-G80 10-bolt failures have we seen on our trucks? I'd really like to know.

 

Silveradoo L33 Said It Would Add 250 Lbs In Weight. Does That Mean 14 Bolt Over 10 Bolt. 250lbs Of More Weight Thats Alot

 

I just broke my Ten bolt... More then likly due to to big tires, decent power and a Manual Transmission... Sad part is that I wasn't even trying to break it!

 

Yeah I do plan on going with over 500 wheel horsepower by the end of spring. I'm have a LQ9 built after Christmas. I'm also looking for 4L80 as well. I wanna go ahead and have the drive train bullet proof before I go throwing all that motor in it. My cousin had one put into his truck, and we did the research and it only weighs 8 pounds more. But there is more rotating mass.
