Detroit Truetrac Vs Locker

Locker or no locker, that is the question. For many off-roaders, this is a difficult decision to make. Both have their pros and cons, but which one is right for you?

In this blog post, we’ll be comparing the Detroit Truetrac vs the Locker to help you make a decision. The Detroit Truetrac is a limited slip differential that uses clutch packs to provide torque to the wheel with more traction. It is effective in both on and off-road conditions and does not require any maintenance.

The main downside of the Truetrac is that it can be less effective in extreme off-road conditions where one wheel may be completely unloaded (such as when crossing a ditch). The Locker, on the other hand, is an electronic or air-activated device that locks both wheels together when engaged. This provides 100% traction to both wheels at all times, but can cause problems on pavement (such as increased tire wear) and can be jarring when engaging/disengaging.

Lockers are also not recommended for use in vehicles with open diffs due to the increased stress on the drivetrain components.

If you’re looking at different locking differential options for your Detroit axle, you may be wondering what the difference is between a Truetrac and a Locker. Both are great choices that offer different benefits, so it really comes down to what’s important to you. Here’s a quick rundown of the key differences between these two locking diff options:

Truetrac: -Uses gears instead of clutches to create friction and lock the axles together, meaning it’s much smoother and quieter than a locker -100% automatic, meaning it will engage when needed without any input from the driver

-Won’t bind up like some locker designs can when turning or under light loads Locker: -Clutch based design means it will be louder than a Truetrac

-Driver needs to manually engage/disengage the locker as needed (usually with a switch)

Detroit Truetrac Vs Locker


Is Detroit Truetrac a Locker?

A Detroit Truetrac is not a locker, but rather a limited slip differential. Limited slip diffs are designed to keep both wheels moving under power, even if one wheel begins to slip. This is accomplished by transferring torque from the slipping wheel to the non-slipping wheel.

The amount of torque that can be transferred depends on the design of the diff and how much power is being applied. While a locker will lock both wheels together so they turn at the same speed, this can often lead to traction loss and excessive tire wear. A Truetrac, on the other hand, will allow both wheels to turn at different speeds when necessary (such as when going around a corner) while still providing traction where it’s needed most.

Are Truetrac Diffs Good?

If you’re looking for a high-quality, durable differential, the Truetrac is a great option. Its unique design uses cone clutches instead of traditional friction plates, so it’s much less likely to wear out over time. Plus, it’s significantly cheaper than other comparable diffs on the market.

One downside of the Truetrac, however, is that its cones can chatter when turning at low speeds. This can be annoying and may even damage your tires if it happens frequently. If you do a lot of low-speed driving, you may want to consider another type of differential.

How Strong is a Detroit Truetrac?

A Detroit Truetrac is a limited slip differential that uses a cone-clutch system to provide constant power to both wheels while allowing for smooth operation. It is designed for use in light duty trucks and SUV’s and is considered to be one of the strongest options available. It can handle up to 100% of the torque that is sent to it, making it an ideal choice for those who are looking for maximum traction and power transfer.

How Do Detroit Truetrac Lockers Work?

Differential lockers are designed to keep both wheels of a vehicle driveable even if one wheel should happen to slip or lose traction. The Detroit Truetrac locker is an example of a differential locker that uses a cone-clutch locking system. When one wheel begins to slip, the locker engages and transfers power to the other wheel.

This helps prevent loss of control and keeps the vehicle moving in the direction in which it is supposed to go. The Detroit Truetrac locker is designed for use in off-road vehicles, as well as vehicles that frequently tow trailers or carry heavy loads. It can be installed in either the front or rear differential, and works with any type of axle.

The locker is activated when needed by simply engaging a switch; there are no special controls or procedures required.

Detroit Locker

A Detroit Locker is a type of locking differential that allows for 100% power delivery to both wheels while still providing the traction benefits of a limited slip differential. It is commonly used in off-road and drag racing applications. The Detroit Locker works by locking the two output shafts together when torque is applied, but still allowing them to rotate at different speeds when necessary (such as when turning).

This provides increased traction and launch performance while still allowing the vehicle to turn. The Detroit Locker was first developed in the early 1970s, and has been continuously refined since then. It is manufactured by Eaton Corporation.

Truetrac Problems

If you’re a Jeep owner, chances are you’ve heard of the Truetrac diff. The Truetrac is a locking differential that’s designed to give your Jeep more traction on the trails. It’s a popular choice for Jeepers who want to improve their off-road performance without breaking the bank.

However, there have been some reports of problems with the Truetrac diff. Some Jeepers have reported that their diffs have locked up unexpectedly, or that they’ve experienced vibration and noise from the diff. Others have said that their Truetrac diffs haven’t performed as well as they’d hoped on the trails.

If you’re considering a Truetrac diff for your Jeep, it’s important to be aware of these potential problems. Weighing the pros and cons carefully will help you decide if a Truetrac diff is right for you and your Jeep.

Detroit Locker for Street Use

If you’re looking for a Detroit Locker for your street car, there are a few things you need to know. First off, Detroit Lockers are designed for off-road use, so they’re not ideal for on-street use. They can be noisy and cause tire wear, so if you’re looking for a locker that you can use on the street, we recommend something else.

That being said, some people do use Detroit Lockers on the street and swear by them. If you decide to go this route, we recommend using softer compound tires to help offset the tire wear issue. You’ll also want to keep an eye on your differential fluid levels, as the increased stress of a locker can cause leaks.

Overall, we don’t recommend using a Detroit Locker on the street. But if you do decide to go this route, just be aware of the potential issues and take steps to mitigate them.
