Changing the rear axle final drive from 6 37 to 8 43 will have any effect on the car?

In fact, the 8:43 final reducer was used instead of the 6:37 rear axle final reducer, which reduced the rear axle gear ratio.

Under the condition that the transmission ratio remains unchanged, the transmission ratio of the entire transmission system is reduced. The function of the transmission system is to reduce the rotational speed of the engine output and increase the torque. The larger the gear ratio, the greater the output torque multiple, but the greater the speed drop.

The situation cannot be said to be good or bad. It can only be said that there is another option. If you are often driving on the road, a small gear ratio can make the car faster and have lower fuel consumption, which is a reasonable choice If your car is used in the field, you often need to climb a large slope with heavy loads, so you should choose a larger gear ratio rear axle to make the car more powerful.

In general, the vehicle's wheel alignment parameters are not easily changed. Four-wheel alignment is only required if parts of the vehicle's axle and suspension system have been disassembled, or the chassis and suspension have been damaged due to accidents, or suspension parts have been deformed due to prolonged driving on unpaved roads. Generally speaking, the external faults of inaccurate four-wheel alignment of automobiles are driving deviation, steering wheel not automatically returning, steering wheel overweight or shaking, unilateral eccentric wear of front and rear tires, etc.

Four-wheel alignment is not harmful to the car, on the contrary, it is a means of repairing the car's faults. It's like a person spraining his foot. The doctor massages, massages, and reshapes his bones.

It is only good for the patient, and there is no harm in it. If the patient refuses**, the condition will only worsen. The same goes for cars.

If there is a deviation in the car's four-wheel alignment,If it is not recalibrated, it will not only affect the driving performance of the car, but also cause abnormal wear and tear of the tires. It's yourself who hurts.

The rear axle should refer to the rear axle main reducer of the car, and the 6:37 rear axle main reducer is replaced by the 8:43 main reducer, which actually reduces the transmission ratio of the rear axle. Under the condition that the transmission ratio of the gearbox remains unchanged, it is equivalent to the transmission ratio of the entire transmission system is reduced.

Replacing the 6:37 rear axle final drive with an 8:43 final drive is actually a segment of the rear axle transmission.

This doesn't really have much of an impact, but the speed changes slightly.

It doesn't matter, it has to do with the driver's driving habits.

This has no effect on the car, it is just a personal driving habit.

The original configuration of the car is the most reasonable, so that random changes may cause accidents.

There may be some relationship to the acceleration of the car, mainly depending on the driver's driving habits.

In fact, the ratio has not changed much, and the impact on the car is relatively small.

This should have no effect, mainly depending on the owner's own habits.

This innocuous modification does little damage to the car. It's better not to modify the car.

It is not allowed to modify, and it is illegal to modify the vehicle without permission.

According to the "Motor Vehicle Registration Regulations":

Article 10 If a registered motor vehicle has any of the following circumstances, the owner of the motor vehicle shall apply to the vehicle administration office at the place of registration for change of registration:

1) Changing the color of the body;

b) replacement of the engine;

3) Replacing the body or frame;

4) Replace the whole vehicle due to quality problems.

Of course, the country 3. The standard formula for the United States is now three. If the manufacturer uses two engines in the country, one engine plant, so that the two countries can win 3, smash their own brand. At present, some cities have implemented the four national standards.

7 39=, 6 37= 6:37 The torque is slightly larger, the speed is a little slower It's about the same, first you have to think about why you want to change, you make your own ideas.

Yes, it will be slower, but the horsepower will be more. The speed ratio means 7:39=.

6:37= Refers to one rotation of the propeller shaft and tires. So the smaller the gear ratio, the smaller the torque, and the larger the gear ratio, the greater the torque.

Therefore, after the rear axle is replaced, the speed of the car will be slower, but the car will become stronger.

The old style is not counted, and the Auman car after 06 years is the most 80 horses, except for the inertia of the downhill, the fastest 80 on the flat road

Yes, but it doesn't make much sense, and if it's super, it's good to take a direct step.

It is not allowed to modify, and it is illegal to modify the vehicle without permission. Wu Ye.
