A Comparison between Detroit Locker vs Limited Slip

When it comes to differentiating between a Detroit Locker and a Limited Slip, there are several key differences to consider. These two locking differentials are both designed to improve traction, but they work in different ways and have different strengths and weaknesses. Here is the comparison between them.

The Detroit Locker locks both wheels together when traction is lost, while limited slip differentials will only lock to a certain degree, allowing for some wheel spin. Now, it’s your decision whatever pick for your vehicle.

Locking Mechanism

The Detroit locker and Limited slip both use a locking mechanism to hold the axle shaft in place. However, the Detroit locker uses a locking plate and pin while the limited slip uses a clutch pack. The Detroit locker is more durable and less likely to fail but the limited slip is easier to install.

On-Road Performance

When it comes to on-road performance, the Detroit Locker takes the lead. Because it’s a locking mechanism, it doesn’t allow the wheels to turn independently of each other. This gives you more power and better traction when you need it most.

In contrast, the limited slip differential allows the wheels to turn independently of each other. While this can be helpful on slippery surfaces, it can also lead to wheel spin and loss of control.

Off-Road Performance

When most people think about a locker, they imagine it bolted onto the rear axle of a race car or truck. This is where the locker shines brightest, as it can provide incredible traction in off-road conditions.

The Detroit Locker can keep your vehicle moving no matter how bad the terrain gets, while the limited slip will start to slip and let the wheels spin if things get too rough.

Maintenance Requirements

In terms of maintenance, Detroit Locker and Limited Slip have completely different requirements. For example, Detroit Locker needs to be adjusted from time-to-time, especially after a few thousand miles when the clutch plates may become worn out. You need to adjust the tensioning of the spring packs to make sure they are properly lubricated, and the plates are in good shape.

On the other hand, the limited slip doesn’t need any kind of maintenance at all. You can leave it alone and it should last for a long time without any issues. This is why many people opt for limited slip differential over Detroit Locker, since they don’t have to worry about adjusting or maintaining it every few thousand miles.

So, if you want something that requires minimal maintenance, limited slip might be the better option for you.


When choosing between a Detroit Locker or Limited Slip, one thing you must consider is their compatibility with different axles.

The Detroit Locker can be fitted with any type of axle shaft, as long as it fits the corresponding bolt pattern. You also don’t have to worry about converting to a different type of axle set when switching locker types.

Meanwhile, limited slips are typically built for more specific axle sets and are not compatible across all types. So, if you’re thinking of changing axle sets in the future, stick to the Detroit locker.


Let’s now talk about price. A Detroit Locker will usually cost you around $400-$500, sometimes even more if you need one for a rear-axle application. On the other hand, Limited Slips tend to be in the $100 – $200 range, sometimes less depending on the application.

So generally speaking, a Detroit Locker is going to be more expensive than a Limited Slip. But as we’ve seen in our previous points, Detroit Lockers also offers superior performance and durability. So, while they may cost more up front, they may be the better investment in the long run.

Detroit Locker vs Limited Slip- Which is Perfect for You?

So, Detroit Locker vs Limited Slip- which is the better option when it comes to vehicle performance? Well, both have their advantages and disadvantages, but if we had to pick a “winner” in this matchup, it would have to be the Limited Slip. It offers superior on-road performance and stability, making it the best choice for street driving and daily commuting.

On the other hand, the Detroit Locker offers superior off-road performance due to its aggressive locking mechanisms. It is also less expensive than the limited slip option, which makes it a more affordable choice for those on a budget.

At the end of the day, both locking mechanisms are great choices depending on your needs and budget. It all boils down to personal preference and what type of driving you plan on doing. Whichever you choose will make sure your vehicle stays stable and secure while you’re out there tearing up roads or trails.

Final Words

Which one is the winner- Detroit locker vs limited slip differential?

Well, it depends on what you need. If you’re looking for the best on-road performance, then the Detroit locker is the winner. It’s smoother and more responsive, and it won’t affect your fuel economy. If you’re looking for the best off-road performance, then the limited slip differential is the winner. It has better traction and handling in challenging conditions.

Both lockers have their pros and cons, so it’s important to weigh up your needs and decide which is the best option for you.
