4:11 Gears

If you are someone who is involved with cars, then you must have heard about the gear ratio 4.11, which is often considered as one of the most significant upgrades you can make to your vehicle’s performance. Gearing is the cornerstone of a car’s performance, and switching to 4.11 gears can make a notable difference. In this article, we’ll be discussing in detail about 4.11 gears and how they can impact your car’s performance.

What are 4.11 Gears?

Before we dive into the details, let us first understand what 4.11 gears are. Gears are the mechanical components that transfer torque from the engine to your car’s wheels. The gear ratio, in this case, indicates the number of revolution by the driveshaft to complete a turn of the wheels. In simple terms, the higher the gear ratio, the greater the wheel torque. 4.11 gears imply that the driveshaft will complete 4.11 revolutions for every turn of the wheel.

Impact on Acceleration

The primary impact of 4.11 gears lies in acceleration. Generally, gearing up your car can result in a faster acceleration time. As 4.11 gears have a high gear ratio, they increase the torque to your wheels. The more torque applied to the wheels, the faster your car can accelerate. Most of the stock cars generally come with a lower gear ratio of around 3.21 or 3.73. When you switch to 4.11 gears, it increases the wheel torque, and subsequently, the acceleration time.

Impact on Top Speed

Switching to 4.11 gears can negatively impact your car’s top speed. As 4.11 gears increase the wheel torque, they can result in a lower top speed. As the gear ratio increases, your engine has to work harder to maintain the torque, eventually limiting your car’s top speed. Therefore, 4.11 gears may not be an ideal option for those who are looking for excessively high-speed racing.

Gas Mileage

Switching to 4.11 gears can have a negligible impact on your gas mileage. In some cases, it can even save you fuel. When you are accelerating quickly, you are using more fuel. However, when you reach a steady speed, the engine does not have to work as hard to maintain it. Therefore, by reducing the time taken to accelerate with 4.11 gears, it can help you save fuel.

Suitability for Cars

4.11 gears are ideally suited for those cars that are meant for drag racing or short-run circuit racing. Cars that involve high-speed racing on different tracks are not ideal for 4.11 gears. Also, if you have a lot of extra weight, such as if you are carrying heavy loads, 4.11 gears are not for you as they cause your engine to strain more, resulting in losing power.


4.11 gears can be distributed in two forms: complete rear-end and ring and pinion set.

Complete Rear-End

Complete rear-end means that you are replacing the whole rear axle along with the 4.11 gears. Unlike changing the ring and pinion, replacing the entire rear axle is a much more straightforward process. The only downside is that it can be more expensive than the ring and pinion set. However, it can be an ideal option for those who have a rear-end that is getting worn out, and they are looking for an upgrade option.

Ring and Pinion Set

The ring and pinion set refers to the process of changing only the ring and pinion gears without replacing the whole rear axle. This option can be more affordable than a complete rear-end, but it requires more work and experience. Mechanic or auto engineer who has experience with changing the gear ratios should perform it. This option can be ideal if you have a newer car or if you are worried about tampering with the rear end directly.


When it comes to installing 4.11 gears, it’s best to leave the job to the professionals. Installing them requires extensive mechanical expertise, and it should not be done as a DIY project. The mechanic or auto engineer should have experience with changing gear ratios, specifically rear-end gear ratios.


4.11 gears can be an excellent option if you are looking to improve your car’s acceleration. However, before you make any modifications, it is essential to consider the compatibility of 4.11 gears with your car’s make and model. With this article, we hope we were able to provide you with a comprehensive guide on everything you need to know about 4.11 gears. Remember, when it comes to making modifications to your car, always do your research, and leave it to the professionals.
