Depends on where you run. If you run Texas exclusively, you'll get better MPGs with shorter rear end gears, such as 3.25s or 3.36s. But you won't get better fuel mileage with such short rears in the mountains.
All you need to do is call a Chevy dealer and give them the VIN# and asked them what the gear ratio is in your truck and they will tell you what the factory gear ratio is.
You need to write your VIN# down and call a Chevy dealer and ask for parts. Then tell the parts man that you have the VIN# and you would like to know the gear ratio in your truck. He'll tell you what gear your truck came factory with.
I'm not real sure what your question is but I'll try to answer. In all cases speed within a gear selection depends on your trucks rear differential gear ratio. If you mean what is the lowest speed you can shift to third gear you should be able to drive on flat surfaces as low as 20 mph. If your truck seems to run well you are OK. If your truck jerks or seems to be laboring, you probably have a very high gear in the rear end and may need to wait to about 25 mph. If you are talking about the maximum speed you can go in third gear you will know when you reach it because you will have also reached maximum effective RPM on your engine and the truck will simply not go any faster in that gear.
If you call the dealer and ask for parts thay will tell you. You need to write down the VIN# so you can give it to him and ask him what the gear ratio is in your truck.
It could be any gear ratio. what you need to do is remove the rear end plate and count the teeth on the ring gear, then count the teath on the pinion gear. and divide the pinion teeth # into the ring gear teeth # and that will tell you for sure just round the # off you come up with.
To know for sure, You need to remove the big metal plate on the rear end housing and count the # of teeth on the BIG round gear / Ring gear. Then count the teeth on the small round gear / pinion gear that sets deep in the housing and runs on the big gear. Then divide the small # into the high # and that will be you gear ratio.
All you need to do is write the VIN# down and call a GM dealer and ask for parts. Tell them you would like to know the gear ratio in you truck, and that you have the VIN# Thay will tell you what it is.
They put several different ratios in that year. You need to write the VIN# down and call a Chevy dealer and ask for PARTS, tell the parts man that you have the VIN3 and you would like to know the gear ratio in your truck. He'll tell you.
It could have, All you need to do is call a GM. dealership and ask for parts. Then ask the parts man if he can tell you what the gear ratio is in your truck. He will ask you for the VIN# so you need to have it wrote down so you can give it to him. Ask him what the gear ratio is and if it's positive trac.
That depends on the gear ratio in the rear ends, not the engine. To make the truck have POWER with those big tires you need at least a 4.10 gear in the rear ends.
48/16 is a decently high road ratio. Pulling a wheelie with that is going to be difficult.
It depends on what you need - if you want lots of speed no power on the bottom end you go with the high ratio - if you want lots of torque on take off and lots of pulling power you take the low gear ratio.
