I have 2005 Silverado ext cab 2wd with 5.3. It has headers, cat back, RPM transmission with 3000 stall, cam, and head work. Next thing is differential and gears, now it has g80 with 3:23, thinking about an Auburn limited slip with 3:73. Any suggestions. Thanks

 

What do you use the truck for? Like a daily or something you'll drag often??

I'd say 3.73's or 3.90's are awesome for just a cruiser/keep fuel mileage, go higher like a 4.10 if you wanna hit the strip alot.

 

I have 4.11s and a 30.5 tall tire and i get 20mpg hwy and 15 16 city. I do have a 6l80e tho

 

Mostly its a daily driver. I have 4l60 with 30.5 tires

 

I say 3.73's also especially if you're using it to drive daily. 3.90's are an option as well haven't seen too many people with them though. if you end up going with 3.73's i have a BNIB set for sale!

 

Ok, what's the price?
