In another thread i read to read on the door and that gu2=2.73 and gu3=3.23 what is gu5 equivalent too? Any help is appreciated.

 

I think Gu5 is 3.23's, not sure though

 

GU5 = 3.23

GU2 = 2.73

WU8 = SS

and i dont know a WS-6

 

it does infact mean 3.23s! I know this for a fact as i have looked up every code on my door!

So any suggestions.? Does yours say gu5...

 

[QUOTE=Juicedz28]Suggestions for what? The GU5 RPO code means you have the "performance' gear of a 3:23

 

[QUOTE=WS6NIGHTMARE]
X2, I dont think there is a such thing as GU3

 

That would be a funny prank. Someone asks a basic, simple question, then keeps asking it over and over as people keep telling him the answer over and over. Whoever gets the most correct answer posts wins. So far, Juicedz28 is up to 5 correct answers in the first page of his post.

Here. I'll add to his point total: The GU5 RPO code means you have a gear ratio of 3:23.

 

Im just post whoring anyway....

 

[QUOTE=Juicedz28]Suggestgions?? i just told u what it means, and yes that code is on my door, but incase ur not sure, u could always do a poll!!!

 

[QUOTE=gyrene2003] I vote for a poll

no really GU5 means its a 3.23 rear gear

 

Sorry i misread your post. Thanks guys.

 

No problem, they're just kidding you. BTW, my door says GU2 because it originally came with 2.73's, but now has a 3.42 complete rear out of an M6 car. So sometimes the codes don't help identify what's actually in the car.

 

Thanks. And thats very true. What would be the correct way to check. Counting the teeth? And if yes. How many is equal to what? Thanks for the help.

 

Joshp14 I believe is the one to talk to for all your future RPO questions. He is the man.

 

Instead of pulling the rear cover visit www.f-body.org/gears/ first and print out what it says for 3.23's - then match it against your RPM on the highway.

 

Nice thanks alot guys. You've been alot of help!

 

WS-6 is WS6 gm was real creative with that one

 

What do you mean how many is equal to what?

Count the ring gear teeth. Then count the pinion gear and divide the two with the ring gear first. That will tell you your gear which is the best way to find out what you have.

 

my car has 3.23 and at 2000 rpm in high gear i'm at 70mph.
