Hey Jon, we were waiting for them to be done at heat treat, but we came accoss a few issues with the axles pertaining to the spline counts, we were origianlly using aftermarket axles (seeing they are more rediliy avaible) however that was a very inconsistent method as the splines on them were all different through the different compaines. We then decided to just go to OEM specs. we already have the driver side ones all done, just need to finish cutting the splines on the driver side, sorry for the delay, we have not made axles before so we are learning as we go, we would assume the aftermarket would be more favorable one, however the materials and composition were of lower grade than the OEM. we just figured we wanted to make them right
Thank you
