  1. There is variance between stock vehicles and what you're really looking for is the proper relationship between the transmission output shaft angle and the pinion angle (equal and opposite). Any kind of "stock" measurement will be irrelevant when it comes to correcting problems on your own vehicle.

  2. I don't understand how people get disappointed get when they buy a mail-order tune and then it doesn't come out like you want. What did you expect? To have the same results as an in-person tune? Even close?

     

    Let's set something straight - there is no such thing as a 'mail order tune.' To 'tune' something you have to have it right there in front of you in order to be able to tune it. So what you're actually ordering or buying is not a 'tune', it may as well be called a SWAG.

     

    That's it - from now on, to add a bit of realism to the situation, start calling 'mail order tunes' 'mail order SWAGs'...since that's really what they are. That way, people might reign in their expectations on what can be accomplished from 1000 miles away.

  3. As far as brand. I'd probably say the factory gears, made by AAM would be the easiest to set up and more than likey run a little quieter than some brands while only giving up a little in strength.

    There's no strength trade-off going with stock/AAM gears; the stock gears are actually stronger and quieter than aftermarkets. The only downside to AAM gears is cost - they are marginally more expensive than Yukon, Motive, etc. gears.

     

    Call Randy's Ring and Pinion in Washington (state) for the best deal...somewhere between $200-$225 if I recall correctly.

     

    Fluid depends on your carrier - with the G80 you can use synthetic; with an LSD you need to run 80/90 gear oil with additive.

     

    I certainly noticed a performance difference going from 3.73's to 4.10's in my Avalanche.

  4. I did a lot of research into torsion bars and spring rates when I was looking at lower my Avalanche. The definitive answers I got were:

     

    - Whenever you adjust torsion bars, you change their spring rate

    - You cannot adjust or change height without also changing spring rate

    - Changing via keys or bolts is irrelevant, both change height and spring rate

     

    Anyway, don't know if this helps, but I thought I would offer what I found.
