depends upon the truck, diffrent ratio's were used
Depending on the differential gear ratio, anywhere from 17 to 19 mpg.
Same as the rear.
You'd have to look at the RPO code in the glove compartment to determine this, as there were a couple different options. The gear ratio for the front and rear axle will match.
9.4:1
1.5:1
The stock gear ratio for a 1995 Chevy Blazer is 3.73. This provides a good balance of fuel economy and power to the rear wheels.
The ratio is 9.5.1 in the 350 vortec. Doing a compression test you should not have any below 100 psi and all should be similar to each other.
I have a 2002 Blazer with the 4.3L engine and 3.73 differential gear ratio, it gives me 17 mpg on average.
3.73 if you have a 350good engine and automatic transmission
depends on the year and drive ratio. the 98-03 z71 silverados had 285 h.p. stock. that was a vortec intake 4L60E trans. and 3.73:1 gear ratio in the differential.
I would be suprised if you have adjustable valves.
In the glove compartment, there'll be a sticker with a bunch of three digit codes. Those are RPO codes, and one of them tells you the gear ratio.
