G80 Locker

[Devious_Tahoe96]

Anyone know if the factory G80 locker stays locked while in 4low/4hi??

 

[bowtiefreak]

no it does not. it locks when it see slippage and I thought only up to 15mph? G80 is not a goof thing for taking abuse.

I believe this is right. It has a mechanical system on the inside that locks up under slippage, and only up to a certain (slow) speed. It also likes to blow up and take your rear axle with it, so be careful.

LMAO!!!
Yeah, thats the last thing i want happening. So basically its only good for a slow crawl on some rocks, not doing burnouts? lol

i have the G80 and want to change fluid when i have them do my transmission. does it call for anything other than gear oil? any additive? do i need to buy a gasket or can i just use the gasket maker stuff that squirts out. plan on using amsoil 75W90 if that matters with the gasket.

Are the new lockers that are in the NBS and NNBS 4x4's the same as the obs one's???

[bowtiefreak]

yes, they all suck

Haha, so just the E80 or Eaton in general.
Been looking at the trutrac, seems the best way to go in the tahoe's, well besides ARB.

A trutrac is a solid choice.

Also, the G80 in the 14 bolts is not bad. Actually, it's a pretty decent set up. Incase anyone is looking into swapping a SF or a FF 14 bolt into their truck. You can convert either axle down to 6 lugs now. Eventually mine will get a trutrac and 4.56's but that is not something to be done right a way

G80 has no problems when it comes to regular street driving? or when paired with a 383 on the road does it?

The 10 bolt G80 sucks. It barley handles stock power. No way would it handle a 383 IMO. But, I've also seen guy's running Turbo LQ4's with the factory G80 and no issues. But, would I trust it? Nope

If you plan on keeping your 10bolt, upgrade to a Trutrac ASAP. However, if you plan to upgrade to a 14SF or 14FF (which I highly recommend anyways) then you would be okay with a G80 for the most part. It has it's flaw's also, but nothing compared to the Govbomb G80 for the 10bolts

But if ones Tahoe didn't come equipped with the G80, and has a limited slip, then the 383 would be alright?

GMT400's didn't come with limited-slips; it was either G80's or open carriers.

someone wanna explain to me what a G80 is? or an E80? or GMT400's and limited slips and all that stuff and how it all works?

G80 is the limited slip differential that GMT400's (88-98 and 92-00) trucks/suv's came with. And GMT400 is the name for that body style. NBS is GMT800 and NNBS is GMT900

A good read on how our limited slips work, when they are in working order lol
