Off-Road Traction for Jeep Dana 35 Axles

Take your Jeep's off-road performance to the next level with the Eaton Detroit Truetrac. Specifically engineered for the Dana 35 rear axle, this helical-gear limited-slip differential is the perfect upgrade for Jeep owners who need reliable traction on loose terrain, mud, or rocks. Unlike lockers that can be harsh on the street, the Truetrac provides smooth, automatic traction that is virtually invisible during daily driving.

Technical Specifications

  • Spline Count: 27 Spline
  • Axle Shaft Diameter: 1.18 inches
  • Gear Ratio Compatibility: 3.54 and Up
  • Rear End Type: Dana 35
  • Operation: Automatic helical gear bias

The Truetrac's gear-based design means there are no clutches to wear out or chatter, making it an incredibly durable choice for off-road enthusiasts. It works by biasing torque to the wheel with the most grip, ensuring you can keep moving forward even when one tire loses contact with the ground. This makes it an excellent choice for Jeep Cherokee, Wrangler, and Comanche owners who want a versatile differential that performs just as well on the highway as it does on the trail. Its maintenance-free nature means you spend less time in the garage and more time on the adventure. If you are looking to improve your Jeep's off-road capability without sacrificing street manners, the Eaton Detroit Truetrac is the solution you need. Find all your off-road drivetrain upgrades at GGCRACING.
