# 3.42 vs. 3.73- Is There a Big Difference You Should Need to Know

The rear-axle proportion is sometimes referred to as the gearbox in some circles. Together with the engine and transmission, it determines how much power your car will be able to produce. To better understand how it works, we can use the gears on a track bike or a mountain bike in principle. The amount of output you get is dependent on the gear you choose.

This also explains how gear ratios operate in automobiles at the most fundamental level. In short, the most significant changes are that the 3.73 gear ratio provides significantly more speed and torque, while the 3.43 gear ratio provides a faster rotational velocity and better fuel efficiency.

In this article, I will compare the rear axle ratios of a 3.48 and a 3.73-inch tire. I’ll go through which one is the most effective for your particular case, as well as how to establish the optimal ratio for your requirements.

## Differences between 3.42 gears, 3.73 and other gears

More concretely, the gear ratio of an automobile is calculated by dividing the number of teeth on the gear system by the number of teeth on the pinion gear. When the pinion is linked to the axle, the engine provides the rotational power for the axle to turn. In addition, the gear ratio indicates how many times the axle must revolve to create a single turn on the wheels.

According to the general rule, the greater the gear ratio, the greater the speed and torque you will obtain from the vehicle. This is why racing cars and massive trucks will have a more excellent gear ratio than other vehicles.

The horsepower and torque produced by them are higher. They accelerate from zero to sixty miles per hour in fewer revolutions per minute and quickly reach top speed. However, they have a slower top speed than other vehicles because of the more excellent gear ratio. In contrast, a lower gear ratio will not accelerate as quickly but will maintain a higher cruising speed for more extended periods.

The implications of this include that if you race two cars with various gear ratios, the outcomes may be substantially different in a stationary starting situation compared to one in which the vehicles roll off the starting line. Many additional aspects come into play, but this simplified explanation should provide you with a decent understanding of what is going on.

### Explaining the most significant difference between 3.73 and 3.42 gears

As previously stated, there is a substantial difference between the two, although both could be regarded as heavy-duty gear ratios. These can be found on trucks such as the Chevrolet Silverado, among other vehicles.

A sizable towing capacity is available. The difference is most visible when it relates to take-off tempo and the time from 0 to 60 kilometers per hour. When it comes to drag racing or city driving, the 3.73 gear will unquestionably give you an edge.

The story will change as soon as the 3.73 hits its top speed. Give them plenty of time. The 3.73 is, therefore, better suited for highway driving, as it has a faster cruising speed and more excellent fuel economy.

### Is a 3.42 axle ratio good?

The 3.55 gear ratio is the best available option concerning this post’s subject matter. This is because it has an equal balance between fuel efficiency and power.

If you already have a vehicle that you use for hauling, hauling, and other heavy-duty tasks, this will be a suitable compromise option for you. Based on the two cars we are discussing in this post, the optimum gear ratio is determined by what you want to get out of your vehicle.

Those who have a daily car that they use for both city and highway travel regularly and who occasionally need to haul heavy loads will find the 3.43 gear to be the most suitable option. If you enjoy rapid acceleration, heavy-duty towing, and pulling capabilities, the 3.73 will be an excellent choice for you.

### Possible ways to know your rear axle ratio

When determining the axle ratio of your vehicle, there are various options. Using jacks or a hydraulic lift, raising your car, and turning one of the back wheels is the first method.

Analyze the number of wheel rotations required to complete a full rotation of the driveshaft. Using this method, you may find out what gear ratio you have. Search for a bit of piece bolted to the rear axle cover if the first method does not yield results.

The axle ratio will be written on the side of the vehicle. However, when it is rusty or broken, the axle ratio is no longer visible and must be calculated by hand. Open the rear axle and count the number of teeth on the pinion and ring gear if you find yourself in this situation.

To find out how many teeth are on the wheel gear, divide the number of teeth on the pinion. Using this method, you will obtain the ratio. In other circumstances, the gear ratio of the ring gear will be inscribed on the pinion shaft of the gearbox.

### Choosing an axle ratio

Several elements, including the engine size, gearbox, ground clearance, and tire size, are considered when determining the gear ratio of a vehicle. The axle could no longer suffice when the car had changed. The most typical scenario is when you perform a lift on your automobile or pickup truck.

A new suspension system and larger tires will be installed as part of this project. These could cause the current axle to become overwhelmed. Unfortunately, there isn’t a straightforward method of determining the appropriate rear axle ratio. The old axle ratio divided by new tire size is the formula for calculating new tire size. The new axle ratio will be calculated due to the above procedure.

The explanation of whether one ratio is better than the other will be determined by the precise requirements you have for your vehicle. Answering this question will assist you in deciding which option is the most excellent fit for you and your circumstances.

### The meaning of RS in Chevy and what is it includes

With the introduction of the Camaro, the RS moniker was given a makeover. A sportier aspect was provided on the Camaro thanks to spotlights with light covers. RS refers to Rally Sport. This package may be available regardless of the trim level you want to buy. Inconsistencies in applying the RS trim to specific other Chevy models caused significant consternation at the time.

RS is an abbreviation for Rally Sport and was first used on the Chevrolet Camaro as a cosmetic package. There is no uniformity in how it is implemented across all Chevy models. It appears as either an aesthetic, performance or trim in other Chevy models.

It is clear from the preceding statement that there is a significant lack of coherence regarding the values that RS promotes. This would most likely be consistent with the original aim of the tag, which was to be a cosmetic package; nonetheless, it tends to confuse those looking for something other than a Camaro.

### Main problems with Chevy cylinders

#### 1. Failed fuel injectors

Some owners have observed misfires and other issues due to faulty fuel injectors in the vehicle. Because these symptoms may not manifest themselves for several weeks after a defective injector has been put, it can be challenging to diagnose the problem. Because most Chevrolet dealerships honor their warranties, they will replace any damaged injectors at no charge.

#### 2. Bolt failure

Crankshaft bolts have been reported to have failed, resulting in catastrophic engine damage in some instances. Those who drive their cars hard or use them for towing are more likely to experience this issue. However, the good news is that it is simple to avoid if you follow proper tightening procedures.

#### 3. Exhaust leak

Drivers have reported an exhaust pipe leak in their cylinder engine, which is one of the more aggravating issues they’ve encountered. It is believed that this problem is caused by excessive heat cycling through cold and hot cycles, which over time produces cracks in the exhaust manifolds.

Sadly, there is no way to resolve this issue short of replacing the exhaust system completely. However, once they have been changed, these funnels should last the whole life of your car.

## Conclusion

You should check the pressure of your tires regularly to ensure that they are not losing air. However, specific models have corrosion issues around the rear axle and the bottom of the trunk lid, which can be problematic in wet weather. This driveline is suitable for most weather situations.

If you live in a very severe environment or have children who enjoy throwing stuff around the back of the car, this might not be the best option for you.
