Customer testimonals

We did a metallurgical comparison, conducted by a testing lab that does FAA forensic work, Pratt Whitney & GE engine parts testing, on Nitro Gear and Toyota ring and pinions. Results are: Both gear sets were identical in metal chemistry, machine finish & Rockwell.

Thank you JustDifferentials and Nitro Gear & Axle, for standing behind a great product. You said to give these axles hell and I Punched them in the face and they took it. Nitro gear and axle fully has my trust and confidence in their product.
