Ok, I have heard of Nitro Gear stuff. I don't know much about them but I clicked on the link and read about their axles and they have the exact same description (1541 material and claim to be up to 30% stronger than stock axles) as the Yukon axles so many people sell. If I were interested in replacement axles with a lower cost axle (compared to Moser's, etc) I'd price check them against Yukon's at places like Mancini's and Dr. Diff. I even saw some on E-bay that were no names that had the exact same description. I may be wrong but my guess is they probably all come from the same Chinese factory.
