I have a 95 Tahoe with a 6" lift 35" tires, and I want to throw on 4.10 gears... (should I go more?)

A) are my measurements correct? (front which is stock) 8.25" IFS
(rear modified to a 12bolt) 8.875"
B) any good brands in particular I should look for?
C) should I go bigger? (4.54)

any other tips and advice would be greatly appreciated, the one thing I do know, is that I dont know enough.

Auburn Gear is pretty good
Detroit True Trac is another option

What about Richmond gear or Superior Gear? Thats all I find for my truck on Summit. Or if you guys know some better sites. Also just to be sure Im lookin for the right stuff, I have a 12bolt rearend(8.875in right?) and my front which is stock is an 8.25 IFS right? I need to take more classes..

phone up THE GEAR CENTER in Edmonton or Calgary, they are really knowledgeable and will steer you in the right direction. They handle many brands and do lots of rear diff work. You can check them out on their website
