These axles are produced using state of the art computer controlled equipment and manufacturing processes.
The first factor to consider is axle shaft steel.
Most OEM manufacturers use 1040 steel.
The axles we offer use 1541h steel (used for high performance applications) ,which contains a lot more manganese, adding to the strength, harden ability and helps in deep heat treating.
These axles are also produced from quality one piece forgings using upset forge methods for strength and consistency.
This upset forging process creates a subsurface grain structure that closely matches the shape of the flange for increased strength and durability.
Putting together the best metals, correct heat treating process, the best induction hardening process and latest computer controlled equipment leads us to believe we are bringing you a first rate product that will serve your needs well.
REAR AXLES GO THROUGH THESE STEPS:
- Upset forging
- Normalize after forging
- Rough turn
- Fine or "finish" turn
- Turning of the flange
- Drill holes for the studs
- Cutting of the c-clip groove
- Splines are rolled
- Final heat treat by computer-controlled induction furnace
- 100% Magnaflux inspection for cracks
- Straightening
- Finish grinding
