4.10 / 4.11

[awesomeame]

i DID a search.

IS there actually a physical difference between 4.10 & 4.11? or is it just how the guy doing the calculations rounds the numbers?

if so....who sells 4.11's for our cars?

& anyone know the deal with this paddle kit that SLP sells? http://www.slponline.com/view_produc...RTNUMBER=64002 i have a 3 series carrier & Zexel LSD...do i need the kit to install 4.10s/4.11s? thanks!

it seems that 4.10 is a Ford gear ratio and 4.11 is a GM gear ratio. my roommate got his 3.73s from motive gear

4.10 gears were an option when we bought our Trailblazer. We didn't get them, but at the time you could pick 3.42, 3.73, or 4.10 gears for no charge. I was looking a couple weeks ago and it's like $40 now, but it would have been nice to be able to get different gears from the factory in F-bodies for $40.
