What is the rear differential ratio of a Lexus GS300?
The rear differential ratio of a Lexus GS300 is 3.727:1. This means that for every 3.727 rotations of the rear differential, the wheels will rotate once. The rear differential ratio is an important specification that affects the vehicle's acceleration, top speed, and fuel efficiency.
Understanding Rear Differential Ratio
The rear differential is a crucial component in a rear-wheel-drive or all-wheel-drive vehicle like the Lexus GS300. It takes the rotational force from the transmission and distributes it to the left and right rear wheels, allowing them to spin at different speeds when the vehicle is turning.
The rear differential ratio is the numerical representation of this gear reduction. A higher ratio, like 3.727:1, means the rear wheels will rotate fewer times than the input from the transmission. This provides more torque to the wheels, improving acceleration from a stop, but reduces top speed and fuel efficiency.
Lexus GS300 Rear Differential Specifications
The Lexus GS300 was produced from 1993 to 2005. The rear differential ratio for this model is 3.727:1. This ratio was chosen by Lexus engineers to provide a balance of responsive acceleration and reasonable fuel economy for this luxury sedan.
Some key points about the Lexus GS300 rear differential:
- Ratio: 3.727:1
- Type: Limited-slip differential
- Gear oil capacity: 1.1 quarts
- Recommended gear oil: Toyota Genuine Differential Gear Oil LT 75W-85 GL-5 or equivalent
The limited-slip differential helps improve traction and stability by sending power to the rear wheel with the most grip. Proper maintenance of the gear oil is important to ensure long differential life.
What is the ratio of rear differentials?
The term refers to the gears in the truck's differential, which is a mechanical device that links the rear axle to the driveshaft and then the engine. Technically, the number should be expressed as a ratio, such as 3.55:1, meaning the drive shaft turns 3.55 times for each turn of a wheel.
What is the final drive ratio of the Lexus GS300?
Final Drive Ratio GS 300: 3.916:1 GS 430: 3.266:1 Suspension 4-wheel independent, double wishbone, coil springs, gas pressurized shock absorbers, front and rear stabilizer bars. Anti-dive and anti-squat geometry. Steering Vehicle-speed sensing progressive rate power rack-and-pinion steering.
How do you tell what ratio a diff is?
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.
What is a 3.73 axle ratio good for?
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.
Is GS 350 better than ES 350?
Quality Rating: The iSeeCars Overall Quality rating for the Lexus ES 350 is 8.7 out of 10 while the Lexus GS 350's quality rating is 8.4 out of 10. This results in the Lexus ES 350 being ranked 2 out of 29 Best Luxury Midsize Cars and the Lexus GS 350 being ranked 7 out of 29.
What does the G in Lexus GS stand for?
Grand Sedan
The GS name stands for Grand Sedan. However, some Lexus importers use the backronymic name, Grand Sport. The first generation Lexus GS began sales in the United States, Europe and selected Asian markets in 1993.
What is the difference between Lexus GS 300 and 350?
The GS 350 and the GS 300 are the same car, so they come with the same features and options; the only difference lies in the powertrain. The GS 350 features a more powerful V6 engine and is available with all-wheel drive.
What is the final drive differential gear ratio?
The final drive ratio is typically the gear ratio for the differential, or the final location where the gearing is altered before being sent to the wheels. Changing the final drive ratio heavily impacts the way the car behaves.
Is the Lexus GS300 2JZ reliable?
