Question:

what is the axle ratio in a 1994 chevy k2500 4x4 z71 extended cab with a 350 or 5.7L?

the truck is lifted and short wheel base, the GVW is 7200, it has 35inch tires on it and you can barely hit the gas while driving it on the grass and the tires will spin i think it has 4-10 gears and thats what im hopping

Answer:

A short wheel base K2500? Hmmm You should be able to tell the gear ratio without removing the rear cover. Jack up the rear end so both wheels are off the ground. Chalk the front wheels, so the vehicle won't move. Put the vehicle into neutral. Using a piece of chalk, make a mark on the drive shaft where you can see it from the side of the vehicle. Make a mark on the tire at twelve o'clock. Turn the wheel and watch for the mark on the drive shaft to come around. See how may times it goes around for one revolution of the wheel. If it goes around a little over four times for one turn of the wheel, then you have 4:11s. 4.1 divided by 1.
I have never used type K on any residential or commercial potable or hydronic heating system, don't buy it for those purposes, it is a waste of money and not required by code. Have only used type K on high pressure gas distribution systems (greater than 125 psi). Yet another reason I don't go anywhere near Home Depot: You've got questions, we've got the wrong answers.
i very own a keep,and intensely a number of those I easily have seen get around 15-20 mpg on an usual foundation,,if there tuned actual and drove actual ,they gets around 18 miles to the gallon on a mushy foundation,sturdy success.
Look in the glovebox. What are the codes that start with G? G80 is the locking diff, any other G code will be the axle ratio. You can easily find an RPO decoder from google that tells what ratio it is, assuming it is still stock. If you suspect it's been changed, pull the diff cover, and look for the tooth counts stamped into the side of the ring gear. It will look like 41:10. Divide 41 by 10 and that would be your ratio. Edit: LOL.rotate the tire and see how many times the driveshaft rotates. Kind of forgot about it being an open differential eh? Stick with the RPO code and/or pulling the diff cover, unless of course you hate actually knowing what you have, and doing preventive maintenance on your rear diff.
Type L and M are both used in residential houses. Type L is actually medium weight and Type K is your heavy weight. Call your codes department in your city and they can tell you the minimum requirement. There is actually a requirement as to what type is allowed to be used.
