We have searched the US to bring you the best axle shafts for heavy-duty and off-road use applications.
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 better than the "common" 31 spline axle you can get other places.
This axle is 20-25% stronger than a standard 31 spline axle like what was used in the larger Broncos!
***Driver and Passenger side 31 spline complete axles with bearings, retainer plates, studs and seals.
***Fits 1974-75 with 10" drum and 88128R bearing(3.15 diameter). 1974, 1975 Ford Bronco
