2pcs Hardened and precision ground to exact size(+/- .0003) for best fitment.  These are intended to be replacement axles for those using thorp brand driveline. These will only work with thorp or similar style steel dogbones.  I will not be making the output cups, clamp hubs or dogbones but the cups and dogbones are already available on ebay.  Unlike the original thorp axles these have the pin hole to drive the wheel hub so clamp hubs not required.  Other change is threads are now M4 instead of 8-32 and threads are also 1.5mm longer for better ease of installation.
