Unlike limited-slip differentials, the Detroit Locker completely locks the axles together, distributing torque equally to both wheels.

The operation of the Detroit Locker is straightforward. When one wheel experiences more resistance or loses traction, the differential engages, transferring power to the wheel with better grip. This automatic and instantaneous locking feature allows you to maneuver through challenging off-road conditions without hesitation.

Pros And Cons

  • Unbeatable traction on all types of terrain
  • Improved off-road performance
  • Enhanced durability
  • Requires minimal maintenance
  • Well-suited for extreme off-roading and rock crawling
  • Steep learning curve for street driving
  • Not recommended for vehicles that primarily operate on pavement
  • Increased noise and vibration
  • May cause tire wear on pavement

With the Detroit Locker, you can enjoy unbeatable traction on all types of terrain. Whether you’re tackling mud, sand, or rocky trails, this differential will keep your wheels spinning and griping the ground as needed.

Jeep Detroit Locker Vs Truetrac



The Truetrac is a highly regarded limited-slip differential (LSD) option for off-road enthusiasts, renowned for its reliability and smooth operation. This LSD is designed to provide excellent traction and handling in a wide range of off-road conditions.

Design And Functionality

The Truetrac LSD is engineered with an innovative helical gear design. This design allows for torque distribution across both wheels, making it ideal for off-road adventures.

Unlike traditional LSDs, the Truetrac does not rely on clutches or friction plates, resulting in a more durable and low-maintenance solution. It operates smoothly and predictably, without any binding or noise, ensuring optimal performance in challenging terrains.

The key to Truetrac’s exceptional performance lies in its gear technology. The helical gears are precision-cut to provide a smooth transfer of power while minimizing heat and wear. When torque is applied to the rear wheels, the helical gears engage, transferring power to the wheel with better traction. This ensures that both wheels receive power, enhancing overall traction and greatly improving off-road capability.

Pros And Cons

  • Reliable and durable design
  • Smooth and predictable operation
  • Exceptional traction in off-road conditions
  • Low-maintenance solution
  • No noise or binding during operation
  • Wide range of applications and vehicle compatibility
  • Not suitable for extreme off-road scenarios, such as rock crawling
  • Less effective than locking differentials in certain situations
  • May require occasional maintenance depending on usage

The Truetrac offers off-road enthusiasts a reliable and versatile limited-slip differential option. Its innovative design and functionality provide exceptional traction and handling, making it an ideal choice for various off-road adventures.

While it may not be suitable for extreme scenarios like rock crawling, its smooth operation, durability, and low-maintenance nature make it highly desirable. Consider your specific off-road needs and preferences to determine if the Truetrac LSD is the right choice for your vehicle.
