G80 FIXED | Gov Lock that can roast tires and drift | Vega EP16 

So much respect for wrecking and not making a click bait video. This video was filled with helpful knowledge and entertainment! Hard to find good youtube channels like this

That dad look had me rolling.

I never actually took the time to science this one out so I’m glad that you did. I’ll be doing this to the old short box chevy in a few days. I will say the g80’s feel amazing when they decide to hook up.

This world needs more people like you. Thank you for making such an amazing video. You are so patient and have so much knowledge.

75 rpm as measured on one axle. The other axle is spinning at 75 rpm in the other direction. The difference in speed between the two is 150rpm. This video was extremely helpful. I've heard of people modifying g80s but this is by far the best demonstration I've seen.

Volvo and Chevy guys gathering round just tryna do skids modding their G80s. Nice.

excellent video! Very useful info!

I love your Vega!

Excellent mod! Just now subbed. Thanks

Lol love the vid unedited and informative

This is awesome! I cant wait to do this on my gmc

thanx, good info, keep burnin!

Damn man, I was wondering if there was a way to mod the G80 to keep it's function over 20mph and this is exactly the kind of thing I was thinking of, instead of just welding it up like most people! Thanks so much for this, my 940 is going to fucking rip now.

YESSS!! My gmc canyon thanks you!

Thxs you just caused the cost of a G80 to go up. That I use in my 78 sunbird and S10. :P But then I never blew one. Instead of welding weights. tweak the springs, It dont take much. I can get my G80 to lock with little over half a turn by hand on the tire. With that being said, I like the idea of welding the unlocking pawl. I cut the one on my sunbird. Go Go Hbody !

Good video and research of an Eaton locking diff. Unfortunately I don't have a locking diff to modify so I'll get a Racing Diffs friction conversion kit to provide a pseudo Torsen action instead. I think it will be kinder for a street orientated application.

How's the longevity been on your gov bomb? I put one in my rambler LS swap project, and am wondering how yours has held up. Love this video, and can't believe it doesn't have more views... Your presentation and the content is great!'I thought you were talking to a man' lol

Interesting... a L.L.L rear end. (Lincoln Locker Light) 🤣. I wondered if you could do something like this. Glad to know it works.

One reason I think yours changed the speed drastically is it likely de-tempered the spring. After reading the comments, I'd probably do it a bit different. I'd weld the disengagement block to only the diff or the weight, but tapped in as a wedge shape. Or just increase the disengage speed by drilling into the weight. I'd also be curious if you could add weight to the engagement flywheel by drilling into them and pounding lead in, like mallory metal added to a crank. You could then tune it to your liking very easily. It would put less weight into the diff - it might not be much given the diff's mass but I'd rather have a rotating assembly with better balance when possible.

Thank you for this vid. I still have the original G80 in my Chevy 1976 K20 pick-up and just tore it apart yesterday to take a good look at it. Everything surprisingly looks great! For years I have been running straight 80-90 wt gear oil in this unit. But now that I know what I actually have. Would you recommend adding a limited slip additive in the gear oil? or is that not necessary since these type of clutch packs don't chatter in the traditional way typical clutch operated LSD work?

Good work 💯💯🦾🤘

I’ve seen this done a few times, great mod but if you ever drive where it’s icy be very careful, my buddy did this on his K1500 and one night he was cruising along about 45mph and hit a patch of black ice with just the pass side tire, which quickly accelerated with the loss of traction. This violent action caused the flyweight housing to crack and send the weights into the teeth of the ring and pinion gears, locking up the rear end and causing the truck to spin 180 and come to a stop, thankfully on its wheels. After this episode he went to a worm gear type LS from a Camaro and had no more worries.

i bought a 1989 4x4 s10 blazer rear end with that Eaton set up to go in my 55 chevy truck, and could get it to lock by spinning the free axle by hand only. Just by a quick snap, like a seat belt locks.

I’ve always wondered if just removing the fly weight springs or adding in weaker ones would do the same thing so they fly out almost immediately instead of having to overcome the spring pressure

Great video! So if I do actually want to fully weld my Gov lock , do I just weld the other side or how would I go about it?

I came across your handle name while searching g body swaps and 8.8 diffs. I just got this type of diff carrier along with GM 8.6 10 bolt from 2000's trailblazer. I was wanting to know if this model is more drag strip drift type mod or can be used safely on street since this video is older you have had time to give accurate information about it. Thanks and new sub' now.

I jacked my 02' Blazer ZR2 up after changing the rear driver's side wheel bearing & I discovered that I had a G80 Locker in mine. With it jacked up, the passenger side spins in neutral & kicks that locker in & out. I've never noticed chirping or anything but it seems to lock up at 100rpm or just a tad higher But, in neutral it's below a 100rpm's but that pass side is spinning faster & it locks up, then I guess as it slows, it disengages, then it locks again & repeats. I still have a bearing noise & most all of the noise is coming from that diff but everything in there looked great & was tight, no noise when I was spinning it by hand to pull that drivers axle out. Maybe the pass side bearing is shot, there is in/out play on the pass side but no play on the driver's side because that axle fits very tight in that bearing. It has me baffled

I end up with gov lockers in pickups, but the harsh lockup leads to damaging axle hop and harsh shock to the drivetrain in even light to moderate offroading. this mod looks great for people with the factory gov locker in their pickups. Seems like I'd have to tune my weights to act right for the application. ps: it looks like you live in my mother in law's neighborhood (vegas/summerlinn, nv)

Best video I found my far. Do you think it would be worth to do in a daily driver 2500hd duramax? I have a g80 as well. Currently doesn’t engage at all. Need to take the cover off and see what’s up

Definitely doing this to the g80 4:10 I got for my gmc envoy from the junkyard today

Do you have to weld shut the unlock paw? I didn't quite understand why you did that. Great video. I got a 14 bolt with this locker and I want to do the same thing

8:33 sounds like a squeeling belt!🤣

👍👍

In an off-road application do you think allowing the engagement to occur at a lower rpm would lend itself to greater reliability? I already blew a g80 up in my Colorado and want to make this one last but still wheel it hard. Also what was the weight you applied to allow the engagement you desired?

Great video! I have seen countless videos of idiots complaining about how bad they are. I loved my 79 k5 with cucv swapped differentials and the "gov locker"

Could you possibly use weaker springs on the engagement side and stronger springs on the disengagement side? Just an alternative idea.

So welding the bottom one stops it from disengaging after 20mph

Have done this to two friends gov lock and it works. But if all you're doing is burnouts mini spools are cheap

In honesty the reason these G80s grenade is because the lockup at high rpm difference produces more impact on the assembly. So if they had just done this from factory it would be a more effective locker, and the chance of it grenading would be far less. I think the 20 mph thing is fine actually should be tuned to like 40 mph. Seems like someone or eaton should make different weighted parts so they can be swapped to a users desire.

I like your idea, but see a possible issue with the locker not being able to dis-engauge. You'd be able to change when the disengagement arm activates by where you place the weights on the arm. A weight at the tip would cause the arm to activate sooner while a weight from the heel to the middle would delay the activation of the arm.

What was that pressurized red spray bottle you were using? I assume it allows you to use kerosene or turpentine for pennies on the dollar and can be pressurized with shop air? I want!

Great video man how is the locker holding up?

Hey just wondering if this mod will help my situation Ls swap s10 with a 7.6” 3.73 that will spin both tires on even surface for 300ft but the slightest try of a donut and it kicks the wheel out If I do this paw weld mod will it stay posi 100% or stay posi longer then usual but still work somewhat normal will driving ?

I’ve got this same rear end in a GMC Sierra. The pen holding the lock broke. Is there anyway I can fix without replacing.

That made my laugh 😂😂😂kids kids kids

Find a Milwaukee Hole Hawg I think a detroit locker would be better suited for what you're trying to do.

You should try using earth magnets instead of welding extra metal ! I bet it would work!

Will it unlock when your going into a curve at like 45 or 50 or is it still dragging a tire

Got same rear ended set up in my 92 Sierra c1500 honestly find that set up not worth a F*** on a sheet of ice tryed Forward & backwards with the brakes to lock it sitting on ice won’t lock but try in snow locks right up if I hit hard enough

Did you end up putting weld on both the little counter weights or just one?

Would I be able to just weld a price on the bigger weight without messing with the smaller one or no? My 86 m1009 has the g80

I have a 14 bolt g80 with the locker is there any way to remove the locker system, mines stays locked once in a while and tire start dragging.

What spray bottle is that? I could really use one of those. Thank You !!!

Do you have any more information or did you find information on how to do this somewhere/what exactly you did? I'm guessing that you added weight to whatever governor weights the unit has in it but I'd bet that 99% of even gear heads don't know what's in a G80 gov lock. Did you mention that it doesn't work right in reverse?

With the axles that these cars have if you weld the diff it will be impossible to remove the axles

Just a quick question, Does it still unlock? And how does it unlock? Thinking about doing this to my car but i don't want it permanently locked though

So I can do this to my 2002 avalanche the has g80?

So what would happen if you took the governor out completely??

Wouldn’t weakening the governor spring be easier and safer than welding? Likewise, put more tension on the lockout governor spring and you’ll get lockup above 20 mph.

Just tack the flyweights together, open diff.

What about balance, wont this vibrate apart?

Why would you borrow someone's drill if you thought you were gonna trash it 😂

😂 whoops

I’ve never had any complaints about how fast it engages but that release has screwed me up many times.

Does it have 373 gears as stock?

A lot of chatter but I had a stock g80 that was a beast.

How has it held up this far, anything you'd do differently? Thanks

So hows the road manners after this mod

So is it now allways locked?

Does this affect everyday driving, I’m sorry I know this is a stupid question

How’s it holding up? Still going ?

So when does it disengage?

is the G80 supposed to make a clunk noise when it engages?

Lighten the weights?

You are shooting at the wrong target, the speeds are controlled by the spring pressure. If you increase the spring rate on the big weight and decrease the spring pressure on the small locking device, I think you would accomplish your goal. I believe there is a conventional 7.5" posi out there also. OEM somewhere in the past. And a cone type in place of clutch packs also OEM.

Used car possi. 88 and older Camaro, or any of the "G" bodit

this is ironic mine will only cook one wheel from a dead stop but will spin both from a 40 roll

How much horse power are you making

id like to buld a vega with a 700r4

Quick fix. I welded mine and it eats tires

A few months that will explode. Lol

A g80 in a 4door s10 blazer is pretty fragile huh? Lil 7.5 10 bolt 🤣

Rule #1 never shit where you lie your head down to sleep, you could pick a better spot for your burnouts besides your own neighborhood

a man's car always finds a way to knock him down a peg. be it dumping oil down the strip or almost perfectly executing a drift.

GM says 120 rpm differential speed.

I swear 100% on a Lincoln Locked diff once you drive with a locked diff you wont settle for less G80 and others are a great choice also. Sir cool video Thumbs up, but trim that scroungy ass beard Sir ahaa haaa haaa haa..........

It does not I repeat not have a clutch

Clutch style is 10x better

Remove the gov lock and buy a different brand. These do not hold up to abuse.
