sold!

Just pulled them out of my truck with less than 5K miles on them. Nothing wrong with them. They were set-up properly and were quiet as a mouse. I just switched to another ratio.
They will fit any 8.5/8.6 10-bolt chevy rear end from 1975-current.

$150 shipped to the lower 48.

 

Still for sale. If you didn't know the 4.30 ratio is $230 a set new and not the std $180 for others.

 

what did you have before the 4.30? how much of a difference in gas mileage. i was gonna do 4.10. right now i have 3.73. can i install with a regular instal. kit?what im mainly interested in: how much mpg did you lose, and how much of an rpm increase was it, say at 70-80 mph? i may be interested.

 

He's t-56 not an a4

3.73-4.30s will increase rpms @70mph by 350 rpm.

 

hey hold on here.... i want em. what rpm were u in 6th? i havent even got to use it yet. im on 20's with 3.42s

 

With my 275/55-20's it was 1950 rpm @ 80mph. They would work better with a shorter tire.

 

ill give you lil bit of a comparison i went from 3.42 to 4.10s and just over 2000 rpm's at 65 and i was getting like 22mpg now im getting around 17 to 18 which is still pretty good.

 

gears are sold.
