Magnum Knuckle Kit

14 Bolt Chromoly Steering Knuckle Builder Kit

Availability: In stock

Crane Axle builds the ONLY 8620 Chromoly Steel outer knuckles on the market! Using 8620 Chromoly Steel instead of cast iron allows us to produce a lighter and stronger knuckle.

Crane's interlocking high-steer arm design eliminates the need for a 5th or 6th bolt for strength. Instead, the High-Steer Arm is keyed to make it possible to put the load on the Knuckle instead of any studs. This is a drastic improvement to strength. The Crane knuckle utilizes 9/16" hardware on the upper kingpin caps and steering arms.

The kit includes:

  • 2 - Crane Interlocking Outer Knuckles
  • 2 - Crane Inner C's
  • 2 - Crane Interlocking High-Steer Arms
  • 2 - Crane Kingpin Caps
  • 1 - Crane Premium Upgrade Kit
  • 1 - REV-14 Seal System
  • Hardware

If you need a 14 Bolt Front End, the Crane Extreme Duty Interlocking Knuckles is the best possible option you can add on.

Why 8620 chromoly?

8620 alloy steel has a much higher carbon content than mild steel. The higher amount of carbon means 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.
