Why. How many axle have you shortened. My car has been running 1.18 60' times for over 15 years on these axles. If you search the Bullet there are a lot of other people who use a cut off wheel on them too.
Some manufacturers will gang run axles with very long splines and chop them to length. If you happen to have a set with long splines, I suppose this can be done. But a good axle is made with the proper spline length for the spool being used and the proper taper and spline major and minor diameters. On these you can't just chop them off.
