What is the rear end gear ratio for a 2000 Chevy Silverado?
The rear end gear ratio for a 2000 Chevy Silverado is typically 3.73:1. This means that for every 3.73 revolutions of the driveshaft, the rear axle will rotate once. This gear ratio is common for the 2000 Silverado and provides a balance between fuel efficiency and towing/hauling capability.
Understanding Rear End Gear Ratios
The rear end gear ratio is a critical specification for any vehicle, as it determines the balance between engine power, fuel efficiency, and towing/hauling capacity. A higher gear ratio, such as 4.10:1, will provide more torque and better acceleration, but will also result in lower fuel economy. A lower gear ratio, like 3.73:1, will offer improved fuel efficiency but less low-end torque.
The 2000 Chevy Silverado was available with several different rear end gear ratio options, depending on the specific model, engine, and intended use of the vehicle. The most common rear end gear ratio for the 2000 Silverado was 3.73:1, which was well-suited for both everyday driving and light-to-medium duty towing and hauling.
Factors Affecting Rear End Gear Ratio
Several factors can influence the choice of rear end gear ratio for a particular vehicle, including:
- Engine size and power: Vehicles with larger, more powerful engines may benefit from a higher gear ratio to take advantage of the additional torque.
- Intended use: Trucks and SUVs used primarily for towing and hauling will often have a higher gear ratio, while vehicles focused on fuel efficiency may have a lower ratio.
- Tire size: Larger tires can affect the effective gear ratio, so the rear end ratio may be adjusted to compensate.
- Transmission type: Vehicles with automatic transmissions may have different gear ratio requirements than those with manual transmissions.
By understanding the rear end gear ratio and how it affects a vehicle's performance, owners of a 2000 Chevy Silverado can make informed decisions about modifications or replacement parts to suit their specific driving needs.

What is the rear axle ratio of a Silverado 1500?
The 2025 Chevy Silverado 1500 offers a 3.42 axle ratio on traditional gasoline models, or 3.73 on diesel models. The Silverado HD models offer 3.73 on all 6.6L V8 models, or 3.42 on Duramax models.
How do you tell if you have 3.73 or 4.10 gears?
You can tell if you have 3.73 or 4.10 gears by manually counting, checking the differential cover for a tag, or finding the ratio stamped on the ring gear. The most direct method is to lift the rear wheels, rotate one tire one full revolution, and count how many times the driveshaft turns; 3.75 turns indicates 3.73 gears, while slightly over 4 turns indicates 4.10 gears.

Method 1: Manual count (with the vehicle jacked up)
- Jack up the vehicle: Safely lift the rear of your vehicle and secure it on jack stands. Ensure the wheels are off the ground.
- Mark the driveshaft and a tire: Place a mark on one of the rear tires and a corresponding mark on the driveshaft.
- Rotate the tire: Rotate the marked tire forward one full revolution. For an open differential, you may need to lift only one wheel and have someone hold the other stationary, or lift both wheels and rotate one tire twice while the other tire is on the ground. For a locked differential, lift both rear wheels and have one tire rotate once while the other rotates once in the opposite direction.
- Count the driveshaft turns: Count how many times the mark on the driveshaft has rotated.
- 3.73 gears: The driveshaft will turn approximately 3.753.753.75 times for one full tire revolution.
- 4.10 gears: The driveshaft will turn a little over 444 times for one full tire revolution.
Method 2: Check the differential cover tag
- Locate the tag: Look for a small metal tag that is usually bolted to the differential cover. It may be on one of the bolts.
- Read the ratio: If the tag is still present, the gear ratio will be stamped on it. It will likely be a number like "3.73" or "4.10".

Method 3: Read the ring gear stamps
- Locate the ring gear: This requires removing the differential cover to get a clear view of the ring gear.
- Find the numbers: Look for two numbers stamped on the teeth of the ring gear, such as "41" and "11".
- Divide the numbers: Divide the larger number (teeth on the ring gear) by the smaller number (teeth on the pinion gear).
- 41÷11≈3.7341 divided by 11 is approximately equal to 3.7341÷11≈3.73
- 41÷10=4.1041 divided by 10 equals 4.1041÷10=4.10
