20% Grade Hill

Without an Eaton differential, rollers under the left rear wheels of this truck would prevent it from climbing the steep 20% grade in this test area.

Mud moguls

An extensive series of moguls are used to test the effectiveness and reliablity of our differentials.

Mud bog pit

Our mud pit simulates real-world off road conditions.

Rock Run
