Eaton ELocker4 Selectable Differential for Toyota

Conquer the toughest trails with the Eaton ELocker4, the ultimate selectable differential for Toyota enthusiasts. Designed for drivers who demand traction on-demand, this electronic locking differential allows you to transition from an open differential for smooth street driving to a 100-percent locked unit for maximum off-road capability with the simple flip of a dash switch.

Why Choose the Eaton ELocker4?

  • Selectable Traction: Instant engagement for off-road obstacles
  • Heavy-Duty Construction: Net-forged gears for superior strength
  • Reliability: Proven electronic design for consistent performance
  • Fitment: Compatible with 30-spline Toyota axles
  • Versatility: Perfect for Toyota 4Runner, Tacoma, and FJ Cruiser

The ELocker4 is engineered to withstand the rigors of rock crawling and mud bogging while maintaining daily driver comfort. Its robust internal design ensures that power is delivered to the wheels that need it most, preventing wheel spin in loose terrain. Unlike automatic lockers, the ELocker gives you total control, allowing you to choose when to engage the lock for maximum maneuverability. Whether you are tackling a weekend trail or navigating challenging terrain, this differential provides the confidence you need. Upgrade your Toyota's drivetrain with the industry-leading technology available at GGCRACING.
