Does anyone run 3.08 gear ratios in the 1995 thru 2004 Blazer 4x4's.
GM option GU4. I wanted to know if the gas mileage is any better with the 3.08's. We drive around 90 miles per day & a few more miles per gallon would help. We have option GU6 gears. Thanks

 

Yes you will get better gas mileage with a 3.08 compared to a 3.42 3.73 gear.The smaller the number less rpms on the open highway.Higher the number the more rpms while on the open highway.

 

Thanks for the reply. Do you know anybody that has made this gear change & what the results were?

 

I had the 3.08 on my 81 Malibu.It had decent mpg for having a 350 v/8.The only draw back was it was sluggish off the line.It would fall back on it`s self when I punched it from a red light.If you have a 4x4 it`s best to have atleast the 3.42
