Alloy axles are induction hardened and are ideal for Street and Street-Track applications.
Pro Race axles (Hy-Tuf) axles are thru hardened- the shaft as well as the axle flange, which makes it the ideal choice for hard-core drag racing. Pro Race Axles are for Drag Racing only because they are built for high torsional strength not flexible enough for rough and bumpy streets.
