I have a full size 89 scottsdale chevy blazer. I'm pretty sure the factory size tires were 31 inches, maybe 30. I now have 35 inch tires and need to get bigger gears front and back to get these tires goin faster. Anybody have any suggestions?

 

id say 4.56s if you have over drive and 4.11s if you dont. i ran 411s and 38s on a blazer i had and it was perfect in my opinion but it also had a torquey engine in it to spin it.

any idea what gears you have in it now? ive seen k5s have 2.73s under them. maybe even a 373 might work for you
