I have a 700r4 and 10 bolt rear that now has 3.42 gears from 2 series gears. My wheels are the stock p245 50r16 iroc rims Is it a hard job to change it and where is it? I also need to know what gear I should get and from who.

Thanks for the help

I'm pretty sure you can get the gears from summit. I copied this chart off of a post here on the web-site but I'll be damned if I remember which one...if you do a search on the site I"m sure you'll find more information. I hope this helps!

3.08 has an 9-tooth drive gear (Pretty sure that's anything under 3.23.

3.23's up require a blue 7-tooth drive gear, plus the following driven
gear:

18 tooth (p/n 3987918) Brown = 3.23
19 tooth (p/n 3987919) White = 3.42
20 tooth (p/n 3987920) Blue = 3.45
21 tooth (p/n 3987921) Red = 3.73
22 tooth (p/n 3987922) Gray =3.77

Ozz, the info you posted is for 5-speeds, and this is about a 700R4.

Well damn...thanks for pointing that out. I wasn't aware there was a difference.

That's the chart I was going by for my 700R4...I just ordered a new gear set off that for my 84 T/A.

Thanks for the help guys
