The E Locker is available for a wide range of trucks, SUVs, and 4×4 vehicles. Eaton manufactures different models to fit Dana 30, Dana 44, Dana 60, GM 10-bolt, and Ford 8.8′ axles, among others. Because of this variety, the Eaton E Locker price can vary significantly based on the model number and the vehicle’s axle configuration.

How to Choose the Right E Locker for Your Vehicle
Confirm Axle Type and Gear Ratio
Before purchasing, verify your axle type, spline count, and gear ratio. This ensures compatibility and avoids costly returns or reordering. If you’re unsure, a mechanic or off-road shop can help you identify the correct specifications.
Consult with Professionals
If this is your first time upgrading your differential, it’s wise to speak with experts. They can explain the full scope of the Eaton E Locker price, including all associated installation costs. They may also help compare other options like air lockers or limited-slip differentials depending on your needs.
Installation Considerations
Do-It-Yourself vs. Professional Install
Installing an Eaton E Locker requires mechanical skills, especially if you’re not familiar with opening differentials. The process includes removing the differential cover, pulling out the factory carrier, and installing the new unit with correct torque specs. Wiring the electrical control system also requires care. If you’re not confident, hiring a professional ensures the locker works correctly and doesn’t void the warranty.
Required Tools
- Socket set and torque wrench
- Gear puller (sometimes necessary)
- RTV sealant and gasket tools
- Basic electrical wiring tools
Even if you’re doing the work yourself, keep in mind that improper installation could cause long-term damage to your axle or locker. Always follow Eaton’s installation manual.
