I am going to order a set of 4.11's for my Camaro.

I just want to make sure I order the correct ones........

I was originally looking at 4.10 gearsets but have since heard that there is a 4.11 motive avaliable for our cars that is stronger.

I think I may have found the part number but there seems to be more than one set - and I'm a bit confused.

What I've got is part #GM 7.5-411 - but there is also #YG GM7.5-411 and a #YG GM7.5-411T (looks like the "T" stands for thick)

What are the difference between these gears and which one do I want?

If the Y stands for thick, then I suspect it is for a 2 series carrier.

Pandamonkey

Hmm.......since I've got 3.42's that means I have a 3 series carrier I think.....

I guess the gears with the "Y" are not for me? Is that what you're saying?

I'll just have to go to a dealership and get them to look up the correct ones I suppose..............and then buy them someplace else....

Those numbers are not GM parts numbers.

Pandamonkey

Damn........that blows.

I'm having an incrediblely difficult time coming up with correct numbers then........those are all that I could find.

call up thunderracing.com, and ask them if they stock the Motive 4:11's 37/9 cut...but make sure its the 37/9, not the 41/10... some ppl say they have gotten actual 4:11's from them, and others say they got the 4:10's (41/10) cut.
Thats all i can think of

Pandamonkey

Thanks a lot!
I sent an email with questions........they have a gear changing package available. Works out to be a better deal.

Now my only problem is what to do about the speedo being incorrect now.....
Hypertech programmers are too expensive for just that one thing....

Get a flash tune from a place like http://madz28.com/ .

Pandamonkey

Fantastic Idea! I had completely forgotten that website existed.

Thank you so much.

Yea and the package is a great deal from them for 400$...add all those products up indivdiually and its over 450$

Pandamonkey

I don't know anything about this 93 Octane Power tune........but I'll have to see.
