Built from 8620 Chromoly Steel
Unlike traditional cast iron knuckles, Crane Axle uses weldable 8620 Chromoly Steel, resulting in a component that’s both lighter and stronger. This premium alloy offers:
- Tensile Strength: 97,000 psi
- Yield Strength: 57,000 psi
- Enhanced Ductility: Hard outer surface with a tough, flexible core
This means more resilience under high load and longer service life in extreme conditions — ideal for rock crawlers, trail rigs, and race builds alike.
Interlocking High-Steer Design
Crane’s keyed, interlocking system eliminates the need for additional steering arm bolts. The precision machined keys transfer steering forces directly into the knuckle body rather than relying solely on hardware — creating a stronger, safer, and longer lasting setup.
- 9/16” grade hardware for all upper kingpin caps and steering arms
- Maintains tight steering geometry under heavy loads
- Reduces bolt shear stress and steering slop
100% American Made
From raw material to final machining, every Crane Axle component is cast, machined, and quality inspected in the USA. Domestic castings ensure superior metal quality, tighter tolerances, and reliability that imported products can’t match.
Engineered for Real-World Abuse
Crane Axle components are tested in the harshest off-road environments — from desert racing to rock bouncing — to guarantee uncompromised performance. Designed, machined, and tested by professionals who live and breathe off-road, these knuckles withstand the punishment that comes with serious trail use.
