Introducing the MAGNUM KNUCKLE KIT from Crane Axle.

The MAGNUM KNUCKLE is a complete game changer in the world of Off-Road. This is the strongest and lightest knuckle you can find that is able to accept 40 or 47 spline axle shafts with a 2 ½ ton RCV Bell. The Magnum Knuckle is only slightly larger than our Dana 60 Knuckle and weighs only 13lbs more. Now you are able to run even bigger axles and put more power to the ground.  Abuse it more then ever before without the fear of breaking.

Commonly used on a 14 Bolt Steering Axle and a Dana 80 Steering Axle.

100% Made in USA, this 8620 chromoly steel knuckle is truly built to withstand extreme Off-Road abuse.

Why Does Crane Use 8620 Chromoly?

8620 alloy steel has a much higher carbon content than mild steel which translates into increased strength. This material is characterized by a hard outer surface, combined with a ductile interior for higher strength. Minimum properties of 8620 (chrome-nickel-moly) alloy steel; Tensile Strength, psi: 97,000 Yield, psi 57,000.  What does this mean for you? Our 8620 chromoly parts can take more abuse day in and day out then our competition, just ask anyone that uses them.

100% Made in the USA

All Crane Axle products are cast and machined in the USA. Casting in the USA is very important to us so that we can have the quality control that we know the customer will be pleased with. Imported castings are a less superior product than castings produced here in the USA.
