Selectable Locking Power for Dana 44 Axles

Maximize your vehicle's capability with the Eaton ELocker4, specifically engineered for Dana 44 front axles featuring 30-spline shafts and 3.73 & down gear ratios. This electronic, selectable differential is the gold standard for drivers who require the flexibility of an open differential for street driving and the raw power of a full locker for off-road obstacles.

Why Choose the Eaton ELocker4?

  • On-Demand Traction: Activate 100% locking at the flip of a switch for immediate grip in mud, snow, or rocks.
  • Superior Durability: Features advanced net-forged gear technology for unmatched strength and impact resistance.
  • Seamless Integration: Designed to fit perfectly into your existing Dana 44 housing, ensuring a straightforward installation.
  • Dual-Purpose Utility: Perfect for daily drivers that double as weekend adventure rigs.

The ELocker4 eliminates the compromise between handling and traction. By keeping both wheels locked during critical moments, you ensure consistent power delivery to the ground. When the switch is flipped off, the unit returns to standard open operation, maintaining smooth cornering and tire longevity. Trust in the reliability of Eaton's engineering to keep your drivetrain performing at its peak. Upgrade your rig today with this essential component from GGCRACING.
