What is the gear ratio on a 2004 Chevy Avalanche?
The gear ratio on a 2004 Chevy Avalanche is 3.73:1. This means that for every single rotation of the vehicle's driveshaft, the wheels will rotate 3.73 times. This gear ratio is designed to provide a balance between acceleration, towing capacity, and fuel efficiency for the Avalanche's intended use as a versatile pickup truck.
Understanding Gear Ratios
The gear ratio is a critical specification that determines the performance characteristics of a vehicle. It is the ratio between the number of teeth on the driven gear (the ring gear in the rear differential) and the number of teeth on the driving gear (the pinion gear). A higher gear ratio, such as 4.10:1, will provide more torque and acceleration but lower top speed and fuel efficiency. A lower gear ratio, such as 3.73:1, will offer a better balance between power and efficiency.
Gear Ratio on the 2004 Chevy Avalanche
The 2004 Chevy Avalanche was available with two different rear axle gear ratios: 3.73:1 and 4.10:1. The 3.73:1 ratio was the more common and recommended setup, as it provided a good compromise between towing capacity, acceleration, and fuel economy.
The 3.73:1 gear ratio on the 2004 Avalanche was designed to:
- Deliver strong acceleration and towing performance from the Vortec V8 engine options
- Maintain reasonable fuel efficiency for a full-size pickup truck
- Provide a comfortable highway driving experience with the engine operating at lower RPMs
Owners of 2004 Avalanches with the 3.73:1 gear ratio generally report satisfactory performance for both everyday driving and light-to-moderate towing duties. The gear ratio strikes a good balance between power delivery and fuel economy for this versatile pickup truck.
What is the gear ratio for the rear end of a 2004 Chevy 1500?
This model you have to find the RPO code in the glove box sticker. You're looking for GT3=3.42 GT4=3.73 GT5=4.10.
What is the gear ratio for the 2004 Chevy Avalanche z71?
Your Avalanche has a 3.73 gear ratio.
What is a 3.73 axle ratio good for?
The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.
How do I find my transmission gear ratio?
Here's the formula for calculating gear ratio: (RPM x Tire Diameter Inches) / (Final Drive Ratio x Transmission Gear Ratio x 336) = Actual numerical gear ratio to the ground from every revolution of the engine.
How can I tell what gear ratio my truck has?
Check the Differential Cover
The axle may have a sticker, and on the differential cover, you might have a small metal tag that's sticking out that will have the gear ratio stamped on it.
How do I tell what gear ratio my Chevy Vin has?
You don't. That information is not contained in the VIN, UNLESS a specific model only gets one rear end ratio. VIN tells country of manufacture, vehicle make, class, engine type, size, date of manufacture, plant and serial number. That is the ONLY information contained by the VIN.
What gets better gas mileage, 3.73 or 4.10 gears?
To keep it simple, if you want a daily driver and want to save a little on fuel and you care about performance but don't want screaming RPM, then taller gears like the 3.73 ring and pinion are the way to go.
What is the gear ratio of a 2004 4l60e?
GM 4L60-E transmission
| 1 | 2 | 4 |
|---|---|---|
| 3.059 | 1.625 | 0.696 |
How can you tell the difference between a 3.73 and a 4.10 gear ratio?
There is only a 10% difference between 4.10 and 3.73 gears. Unless you need to tow heavy loads, I would keep the 3.73 gears. Or maybe if you are going to big, big tires. Otherwise you probably won't notice the difference. And, If you get some big tires (35-37``) you probably would want to go to a 4.56 or so ratio.
How do I know if I have a 6L80 transmission?
If the 6L80E transmission is still mounted in the vehicle, you can only identify it using its RPO tag in the vehicle's glove compartment. This is why knowing the RPO code for the transmission you want to identify is nothing short of golden.
