What is the final drive ratio of the Lexus gs300?
The final drive ratio is a critical specification in any vehicle, including the Lexus GS300, as it directly impacts performance, fuel efficiency, and driving dynamics. In this article, we’ll explore what the final drive ratio is, its importance, and the specific ratio for the Lexus GS300.
What Is the Final Drive Ratio?
The final drive ratio refers to the ratio between the revolutions of the driveshaft and the rotation of the wheels. It is determined by the gear ratio in the differential, which is the component that transfers power from the transmission to the wheels. This ratio plays a significant role in determining how much torque is delivered to the wheels and how efficiently the engine operates at various speeds.
Why Does the Final Drive Ratio Matter?
The final drive ratio affects several aspects of a vehicle's performance, including:
- Acceleration: A higher final drive ratio provides better acceleration by delivering more torque to the wheels.
- Fuel Efficiency: A lower final drive ratio can improve fuel efficiency by reducing engine RPMs at cruising speeds.
- Top Speed: The ratio also influences the vehicle's top speed, as it determines how quickly the wheels rotate relative to the engine.
The Final Drive Ratio of the Lexus GS300
The Lexus GS300, a luxury sedan known for its smooth performance and reliability, typically features a final drive ratio of 3.91:1. This means that for every 3.91 revolutions of the driveshaft, the wheels complete one full rotation. This ratio strikes a balance between acceleration and fuel efficiency, making it suitable for both city driving and highway cruising.
Conclusion
Understanding the final drive ratio of your Lexus GS300 can help you appreciate how the vehicle is engineered for optimal performance. Whether you're considering modifications or simply want to learn more about your car, knowing this specification is a great starting point.

Frequently Asked Questions
Can you change the final drive ratio?
And changing an entire gearbox can be prohibitively expensive. But if you want better acceleration (or more top speed), there is an easier solution to your problem: Change your final drive ratio. The gears within your transmission aren't the only gears in a car.
What is the rear end diff ratio?
Its the ratio between the driveshaft (input to differential) and axles (output of differential. A 4.11 refers to a 4.11:1 ratio. This means that the driveshaft turns 4.11 times for each time the axles turn once.

What is the diff ratio for a 1998 Lexus GS300?
1998-2005 Lexus GS300 Rear Axle Differential Carrier Assembly 3.92 Ratio OEM.
What is a good final drive ratio?
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 many miles do 2JZ engines last?
If the 2JZ isn't screwed with they've been proven to last for 200k+ miles time and time again. They're super popular for the tuner market because they are massively overbuilt so they can handle a ton of extra power.
