What is the gear ratio for a Toyota transfer case?
As a seasoned auto service provider at Kevin's Autos, I often encounter questions about the intricacies of vehicle mechanics. One common inquiry pertains to the gear ratio of a Toyota transfer case. This article aims to clarify what a gear ratio is, its significance, and the specific ratios associated with various Toyota models.
What is a Gear Ratio?
The gear ratio is a crucial aspect of a vehicle's drivetrain, particularly in four-wheel-drive (4WD) and all-wheel-drive (AWD) systems. It represents the relationship between the number of teeth on two gears that are meshed together. In the context of a transfer case, the gear ratio determines how power is distributed between the front and rear axles, affecting traction and performance.
Importance of Gear Ratios
Understanding gear ratios is essential for several reasons:
- Performance: Different gear ratios can enhance acceleration or top speed, depending on the driving conditions.
- Fuel Efficiency: A well-matched gear ratio can improve fuel economy by optimizing engine performance.
- Towing Capacity: Higher gear ratios can provide better torque for towing heavy loads.
Common Gear Ratios for Toyota Transfer Cases
Toyota vehicles typically feature a range of gear ratios in their transfer cases, depending on the model and year. Here are some common ratios:
- Toyota 4Runner: The gear ratio is often around 2.64:1 in high range and 4.0:1 in low range.
- Toyota Tacoma: Similar to the 4Runner, the Tacoma usually has a high range of 2.64:1 and a low range of 4.0:1.
- Toyota Land Cruiser: This model may feature a gear ratio of 2.48:1 in high range and 3.9:1 in low range.

Frequently Asked Questions
What is the ratio of a Toyota Land Cruiser transfer case?
Transmission Ratio Information
| LAND CRUISER | 1st | T/CASE |
|---|---|---|
| FJ62 – 6 CYL PETROL (3F) – 4 SPEED AUTOMATIC A440F TRANSMISSION – 19T SPLINE TWO PIECE TRANSFER CASE | 2.95:1 | PART TIME 1.959:1 |
| HJ75 – 6CYL DIESEL (2H) – 5 SPEED H55F TRANSMISSION – 19T SPLINE ONE PIECE TRANSFER CASE | 4.843:1 | PART TIME 1.959:1 |
How to increase crawl ratio?
Installing lower gears in the transfer case isn't the only way to alter your crawl ratio. You can change the axle ratio, adjust tire size, or even swap in a lower-geared transmission. An ideal crawl ratio for general-use 4x4s is typically in the 50:1 range.
How to check Toyota gear ratio?
Rotate the marked tire one revolution while counting how many times the driveshaft rotates. eg, If your driveshaft made 3 3/4 revolutions, that would determine a 3.73 gear ratio. If you get approximately 2 3/4 revolutions, you have a 2.76 gear ratio.
What is the current ratio of Toyota?
1.23
Toyota current ratio for the quarter ending September 30, 2024 was 1.23. Toyota average current ratio for 2023 was 1.14, a 4.59% increase from 2022. Toyota average current ratio for 2022 was. Toyota average current ratio for 2021 was 1.07, a 0.94% increase from 2020.
What is the 1st gear ratio of a Toyota?
First Gear: 3.830:1.
What is the gear ratio of a transfer case?
It has a 1:1 ratio drive (usually called high range) for normal city and highway use. Then it contains a low range gear for off-road use. A common low range gear ratios is 2.72:1. That means for every 2.72 rotations of the transmission output shaft, the transfer case will turn both driveshafts 1 rotation.
What is the gear driven transfer case ratio for Toyota?
2.28:1
Throughout the years Toyota used basically two types of transfer cases: chain or gear-driven. All gear-driven cases have the same bolt pattern with a 2.28:1 low gear ratio.
Can you change a transfer case ratio?
An aftermarket gearset replaces the factory gears to change the low-range ratio. An advantage to this solution is that no other external modifications are needed, including driveshafts. Simply install the new gears in the transfer case.
What is the transfer case ratio for the FJ Cruiser?
The FJ Cruiser's two-speed transfer case provides a 2.566 low range. With the manual transmission, the transfer case uses a TORSEN® limited-slip center differential with a locking feature and distributes the engine's power 40:60 under most driving conditions.
What is a reasonable gear ratio?
Good and Bad Gearing Ratios
| Gearing Ratio Guidelines | |
|---|---|
| 50% or more | High-levered, high risk |
| 25% to 50% | Optimal or normal |
| 25% or Less | Low-levered, low risk |
