These Red Dirt Derby Precision machined and polished axels were engineered with an increased diameter of 0.091” where the axle engages the wheel in order to drastically reduce speed robbing wheel wobble. Next, the machining process ensures the axles are perfectly straight for the truest roll. These are not original BSA nails, these are precision machined axles. Check your rule book.
