What is the diff ratio on a Toyota HiLux?
The diff ratio, or differential ratio, on a Toyota HiLux refers to the gear ratio between the vehicle's drive axle and the wheels. This ratio determines the amount of torque and speed delivered to the wheels, which is crucial for the truck's performance and capabilities. In this article, we'll dive into the details of the diff ratio on the Toyota HiLux and why it's an important factor to consider.
What is the Diff Ratio?
The diff ratio, or final drive ratio, is the relationship between the number of teeth on the ring gear (the larger gear) and the number of teeth on the pinion gear (the smaller gear) in the vehicle's differential. This ratio determines the amount of torque and speed that is transferred from the engine to the wheels. A higher diff ratio, such as 4.10:1, means the wheels will turn more times for each revolution of the driveline, resulting in more torque but lower top speed. Conversely, a lower diff ratio, such as 3.73:1, will provide higher top speed but less torque.
Diff Ratio and the Toyota HiLux
The Toyota HiLux is available with a range of diff ratios, depending on the specific model and configuration. Here are some common diff ratios found on the HiLux:
- 4WD models: 3.91:1 or 4.10:1
- 2WD models: 3.73:1 or 3.91:1
- Diesel models: 3.91:1 or 4.10:1
- Petrol models: 3.73:1 or 3.91:1
The higher diff ratios, such as 4.10:1, are typically found on 4WD and diesel models, as they provide more low-end torque for off-road driving and towing. The lower diff ratios, such as 3.73:1, are more common on 2WD and petrol models, as they prioritize higher top speed and fuel efficiency.
Importance of the Diff Ratio
The diff ratio on a Toyota HiLux is an important factor to consider for several reasons:
- Off-Road Performance: A higher diff ratio, such as 4.10:1, provides more low-end torque, which is crucial for off-road driving and towing heavy loads. This allows the HiLux to tackle steep inclines, loose surfaces, and other challenging terrain more effectively.
- Towing Capacity: The diff ratio directly affects the HiLux's towing capacity. A higher ratio allows the truck to pull heavier trailers and loads with more ease.
- Fuel Efficiency: A lower diff ratio, such as 3.73:1, can improve the HiLux's fuel efficiency by reducing engine rpm at a given speed, resulting in better fuel economy.
- Top Speed: A lower diff ratio also allows the HiLux to achieve higher top speeds, as the engine can reach higher revolutions per minute (rpm) before the wheels reach their maximum speed.
When choosing a Toyota HiLux, it's important to consider the intended use of the vehicle and select the appropriate diff ratio to match your needs, whether it's for off-road adventures, towing, or highway driving.
What is the difference between H4 and L4 Hilux?
L4 is low range 4 wheel. H2 is high range 2 wheel, h4 is high range 4 wheels. L4 is for steep hills or really slow speeds where it's rocky. H4 is for higher speeds but bad weather like snow or ice.
Is a higher or lower diff ratio better?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.
Do bigger tires raise or lower gear ratio?
The tire size affects the overall diameter of the tire and wheel assembly, which in turn affects the gear ratio. The gear ratio determines how much torque is transferred from the engine to the wheels. If the tire size is larger, the gear ratio must be lower to compensate for the increased diameter, and vice versa.
What is the gear ratio of a 2015 Toyota Hilux?
The 2015 Toyota HiLux SR (4x4) has a 210mm ground clearance with a 2500kg braked and 750kg unbraked towing capacity. It has a final gear ratio of 3.583. The Toyota HiLux has received a 5 star rating from ANCAP.
What is the best rear end ratio?
The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy. This is a good ratio for the occasional towing or hauling individual. For a person who tows more often, and heavier loads, the 3:73 or 4:10 may be more appropriate.
What is the diff ratio for a Hilux LN167?
4.55 Ratio
Hilux LN167, 8/97 on, Front Diff Assembly with 4.55 Ratio.
What is the best gear ratio for driving?
To find the ideal selection, multiply the final drive ratio by the redline speed in fourth gear (152 mph) and divide that by the top track speed (140 mph). This would yield a theoretical 3.33—which is close enough to the nearest available final drive ratio of 3.36:1.
How do you use 4WD gears on a Hilux?
Now. We do steering wheel straight in neutral am brake on coach. Down again push.
What diff ratio is faster?
A lower ratio gives better fuel economy but slower acceleration, while a higher ratio provides quicker acceleration but lower fuel economy. This number helps you understand a vehicle's performance and choose the best option for your driving needs.
