The anti spin differential rear axle is a mechanical device that has helped drivers to maintain firm control of their vehicles in slippery or muddy conditions. Thus, drivers have avoided accidents or getting stuck in the mud by simply having this mechanism attached to their vehicles. What exactly is this mechanical device and how does it work?
This article will answer these questions and cover the different types of the mechanical device and its advantages.

What Is a Vehicle Anti Spin Differential Rear Axle?
A vehicle anti-spin differential rear axle, also known as a Limited-slip Differential (LSD), is a mechanical device that transfers power to both rear tires, enabling them to spin at the same speed in poor traction areas. This prevents the car from getting stuck or drifting out of control.
– How It Works
When one of the rear tires loses traction and begins to spin, the vehicle transfers more power to the tire with traction, causing both tires to spin at the same rate. This helps the driver to control the vehicle and steer it out of harm’s way. For example, the 2022 Jeep anti spin differential rear axle is designed to enable the Jeep Wrangler to tread all kinds of terrain and negotiate different turns without slipping. This is why it is recommended to use the recommended tires and not other big ones. Always prefer the ones that the manufacturer recommends.
There are different types of LSDs and all employ their unique methods to maintain tire traction.
Why should you get an LSD rear axle? With an anti-spin rear differential, the vehicle will hardly get stuck as all it needs is just for one rear wheel to get traction and the vehicle will move. This is different from an open differential rear axle where the vehicle gets stuck once one rear wheel loses traction. There are numerous advantages that come with it including avoiding slipping or getting stuck as well as better vehicle control and performance.
Also, an anti-spin rear differential works to enable a better vehicle performance and driving experience as the wheel with the most traction improves acceleration. This means that when you’re negotiating a turn or curve, the car won’t lose traction. Also, the car won’t skid or drift when you accelerate as the torque delivered to the wheel with a better grip helps you to keep the vehicle under your control.
– Problems Associated With LSD Rear Axle
Differentials are costly and difficult to repair because the clutch plates that cause friction are subject to wear. Other parts of the differentials also wear out with time and will need to be replaced if you want them to function properly.
Then there is the question of their weight and impact on the vehicle. Differentials tend to be slightly heavier and may cause the engine to exert more power than it is used to, which could lead to understeering.
The anti-spin differential rear axle is worth its price because it keeps the vehicle from accidents or getting stuck, however, its maintenance and weight can cause problems for the driver.

What Is Anti Spin Differential Rear Axle Ram 2500? Anti-spin differential rear axle Ram 1500 is a device installed on the Ram 1500 that prevents the vehicle from slipping or getting stuck by providing power to any of the rear wheels of the Ram 1500 that has better traction.
This allows the driver full control of the vehicle, which they steer to safety. This goes for most popular pickup trucks thus, you can have an anti spin differential rear axle wrangler and anti spin differential rear axle challenger.
What Are the Types of Anti Spin Differential Rear Axles?
The types of anti spin differential rear axles include clutch plate, viscous fluids, cone clutch and gear differentials. As demonstrated earlier, all the types of differentials have their unique methods but the goal is the same: to prevent the wheel with less traction from spinning.
– Clutch Plate Differentials
The clutch plate differential, which is the most common type, works by transferring more power to the wheel that has traction. This occurs when there is more separating force between the spider gear and side gear of the wheel with more traction initiated by the engine torque. As a result, the side gears move toward the differential case, kicking the clutch plates into action. The clutches prevent the free-spinning wheel from moving faster than the wheel with traction.
This gives the car enough power and the driver more control to safely negotiate his way out of the sticky situation. However, the car won’t move with its full power due to the friction provided by the clutch plate differentials.
– Cone Clutch Differentials
The cone differentials operate in a similar fashion to the clutch plate, however, the difference is that it uses friction-lined cones instead of clutches. It works by using the engine’s torque to force the side gears and preload spring to kick the cones into action.
The cone clutches then transfer more torque to the high-traction wheel while preventing the low-traction wheel from moving faster. Thus, the car can move out of a muddy or slippery surface with the power from the high-traction tire.
The car only moves with enough force that gets it out of the precarious situation until it can restore high traction in both tires.
– Viscous Fluid Differentials
Also known as the Viscous Fluid Limited Slip Differential, this system works on the same principle as those above which, is to transfer torque to the tire with the most grip/traction. This system makes use of the friction between the viscous liquid and the slower-moving friction discs of the wheel with more traction.
Thus, the wheel with more traction can get enough power to move until the other wheel gets a better grip on the pavement. Though viscous fluids operate smoothly, they transfer less torque and are less durable than their counterparts.
– Geared Differentials
Geared LSDs use worm gears and spur gears to transfer torque to the wheel with the best traction, enabling the car to move to safety. This happens when the axial and radial thrust presses the gears against the differential housing, which causes friction.
This withholds more torque from the wheel with less traction and transfers it to the wheel with the best grip. Geared differentials are long-lasting but are very costly.
So far, we’ve looked at the definition of an LSD rear axle, how it works, and the reasons you should have one installed on your car. Here is a recap of all that this article has covered on this topic:
- The LSD rear axle is a mechanical device that prevents a vehicle from slipping when one of the rear wheels loses traction.
- The differential works by transferring the torque from the wheel with less traction to the wheel with more traction enabling the driver to maintain total control of the vehicle.
- There are several types of differentials including clutch plate, cone clutch plate, viscous fluid and geared differentials, but all utilize the same principle.
- The advantage of getting an LSD is to avoid road accidents or prevent vehicles from getting stuck in mud like the one on the Jeep Wrangler.
- The downside of the differential is that it needs constant maintenance and is quite heavy, which may put an extra strain on the engine.
If you are debating whether or not to get one, it is far better to get an LSD axle as the advantages outweigh the disadvantages. If you have water leaking issues with ur Jeep Wangler when it rains, check out our detailed step-by-step tutorial.
