What is the gear ratio of a 5.7 Tundra?
The gear ratio of a 5.7 Tundra refers to the relationship between the number of teeth on the driven gear (the ring gear) and the number of teeth on the driving gear (the pinion gear) in the vehicle's differential. This ratio determines the amount of torque multiplication and speed reduction between the engine and the wheels, which is crucial for the truck's performance and towing capabilities.
What is the Gear Ratio of a 5.7 Tundra?
The standard gear ratio for a 5.7 Tundra is 3.91:1. This means that for every one revolution of the pinion gear, the ring gear in the differential will rotate 3.91 times. This gear ratio is designed to provide a balance between acceleration, fuel efficiency, and towing capacity for the Tundra's powerful 5.7-liter V8 engine.
Understanding Gear Ratios
Gear ratios are an important factor in a vehicle's performance and capabilities. A higher gear ratio, such as 4.30:1 or 4.88:1, will provide more torque multiplication, resulting in better acceleration and towing power, but at the expense of fuel efficiency. A lower gear ratio, such as 3.73:1 or 3.55:1, will prioritize fuel economy and highway driving, but may sacrifice some low-end torque and towing capacity.
Factors Affecting Gear Ratio Selection
The choice of gear ratio for a 5.7 Tundra is influenced by several factors, including:
- Engine displacement and horsepower
- Intended use of the vehicle (e.g., towing, off-road, highway driving)
- Tire size and wheel diameter
- Fuel efficiency and emissions requirements
- Manufacturer's design goals and target market
Toyota engineers carefully selected the 3.91:1 gear ratio for the 5.7 Tundra to provide a balance between these various factors, optimizing the truck's performance and capabilities for a wide range of driving conditions and towing needs.
What is the gear ratio for a 350 transmission?
Turbo 350 Performance Transmission: Specs
The following are the gear ratios the Turbo 350 features: First gear: 2.52 to 1. Second gear: 1.52 to 1. Third gear: direct drive, i.e., 1.0 to 1.
What is the rear ratio of a Tundra?
4.30 Ratio
What is the normal gear ratio?
The most common gear ratios used in cars are 1st gear: 3.5-4.5, 2nd gear: 2.0-2.5, 3rd gear: 1.5-1.8, 4th gear: 1.0-1.3, 5th gear: 0.8-1.0.
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 much horsepower does a 2013 Toyota Tundra 5.7 V8 have?
381 horsepower
Acceleration and Power
The most powerful option is the 5.7-liter V8, which produces 381 horsepower and 401 pound-feet of torque.
How much rear diff capacity does a 5.7 Tundra have?
From our research the Toyota Tundra 5.7L V8 rear differential has a fluid fill capacity of 3.6 - 3.8 liters (3.8 - 4.01 quarts). The Toyota Tundra 4.6L V8 and 4.0L V6 models were optioned with a rear differential that has a fluid capacity of 4.0 - 4.6 liters (4.8 quarts).
How long will the Toyota Tundra 5.7 engine last?
between 150,000 and 250,000 miles
On average, a well-maintained Toyota Tundra can last between 150,000 and 250,000 miles, with many owners reporting 300,000 miles or more. With proper maintenance and care, there are even documented cases of Tundras surpassing the one million-mile mark.
What is my rear gear ratio?
The large number is the ring-gear tooth count. To find the gear ratio, divide the big number by the little number. In the example to the left, 37 รท 12 = 3.083333. These are 3.08 gears.
What is the gear ratio for a 2007 Toyota Tundra?
The standard gear ratios for the 5.7 are 4.10s; 4.30s come with the tow package. As you'd expect from Toyota, the Tundra is equipped with an alphabet-soup bowl full of computerized traction and ABS controls.
What is the gear ratio for a 2013 Toyota Tundra?
It's a bit odd the Tundra doesn't come with a standard trailer hitch since it includes trailer sway control and a 4.10:1 gear ratio standard. When equipped with the optional trailer hitch, the Tundra can be a monster tow vehicle.
