What is the gear ratio for a 1966 Chevy truck?
The gear ratio for a 1966 Chevy truck can vary depending on the specific model and configuration, but a common gear ratio for these vehicles is 3.73:1. This means that for every 3.73 revolutions of the driveshaft, the rear wheels will rotate once.
Understanding Gear Ratios in Trucks
The gear ratio is a crucial factor in the performance and capabilities of a truck. It determines the balance between power and speed, affecting factors such as acceleration, towing capacity, and fuel efficiency. A higher gear ratio, like 3.73:1, provides more torque and pulling power, making it well-suited for tasks like hauling heavy loads or navigating steep terrain. However, this comes at the cost of top-end speed, as the engine will be turning at a higher rpm to achieve the same vehicle speed.
Gear Ratio Specifications for a 1966 Chevy Truck
The 1966 Chevy truck was available with a range of gear ratio options, depending on the engine, transmission, and rear axle configuration. Some common gear ratios for this model year include:
- 3.73:1 - A popular choice for its balance of power and efficiency.
- 4.11:1 - Provides even more low-end torque for heavy-duty applications.
- 3.08:1 - Offers a higher top speed and better fuel economy, but less low-end power.
The specific gear ratio for a 1966 Chevy truck can be determined by checking the vehicle's identification tag or consulting the original owner's manual or service documentation.
Factors Affecting Gear Ratio Selection
When choosing the appropriate gear ratio for a 1966 Chevy truck, several factors should be considered, such as:
- Engine size and power output: Larger, more powerful engines may benefit from a higher gear ratio to take advantage of the additional torque.
- Intended use: Trucks used primarily for towing or hauling heavy loads may require a higher gear ratio for better low-end power, while trucks used for highway driving may benefit from a lower gear ratio for improved fuel efficiency and top speed.
- Tire size: Larger tires can affect the overall gear ratio, and may require a different ratio to maintain the desired performance characteristics.
By understanding the gear ratio specifications and factors that influence the selection, owners of 1966 Chevy trucks can ensure their vehicles are optimized for their specific driving needs and applications.
How do I figure out my gear ratio?
The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “[result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.
What is the best gear ratio for pulling a truck?
between 3.55 and 3.73
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 know what gear ratio my Chevy truck has?
Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box. Note that using the RPO code for parts identification assumes that the rear end has not been previously modified!!
What is the gear ratio of a NV3500?
Close Ratio NV3500-HD Dodge Dakota Gearing:

| 3.49 | 2.14 | 1.38 |
How can you tell if you have 3.73 gears?
if the driveshaft turned 3 3/4 revolutions for two rotations of the tire, you have a 3.73 gear.
What is a 3.73 gear ratio good for?
For a truck, it is great for heavier loads where factory gear ratios that are 3.55 or 3.31. In a sports car, 3.73 gears will offer better acceleration while retaining top speed when compared to 3.55 gears that come factory on many sports cars.
What is 3.42 gear ratio good for?
For instance, the 3.42:1 ratio included on many Canyon V-6 and Sierra 1500 models offers a good all-around blend. That said, if you regularly tow heavy trailers or prefer a peppier feel in acceleration, consider a truck equipped with a higher numeric axle ratio.
What's the difference between a TH350 and 700R4?
The splines think out about the same on both of these. So you have about a three inch difference in length. But again the primary. Different the primary concern was this was the bell housing.
