Strange 28 30 31 spline alloy axles forged from modified 1550 premium steel majority of machining performed before heat treat to provide consistent hardness induction hardened to rc 58 62 to increase torsional strength while remaining ductile finish machined after heat treat to ensure accuracy choice of 28 up to 31 spline.
They both have the center drilled hole for lathe work. Generally 28 spline have an oval hole on the outboard ends while 31 have two round holes. 31 spline axles also tend to be larger in diameter to accommodate the increased amount of splines.
