Crane Axle GM Dana 60 Rear Steer Knuckle Kit
CA01024
The Crane Axle GM Dana 60 Rear Steer Knuckle Kit is designed around proven Dana 60 kingpin steering geometry for custom rear steering axle assemblies. The kit combines 8620 chromoly knuckles, interlocking high steer arms, inner C's, kingpin components, and required hardware into a heavy-duty foundation for rear steer systems used in rock crawlers, competition buggies, and high-articulation off-road vehicles.
Unlike a Dana 60-specific replacement system, this kit can be adapted to a wide range of axle platforms and fabricated housings. It is compatible with GM 14-Bolt, Dana 60, Dana 70, Dana 80, fabricated 9" and 10" housings, and other custom axle assemblies using the appropriate housing bore. The keyed, interlocking high steer arm design mechanically transfers steering loads into the knuckle instead of relying solely on fastener clamping force, helping reduce stress on steering arm hardware under high-load steering conditions.

- (2) Crane Axle GM Dana 60 Kingpin Knuckles
- (2) Crane Axle Dana 60 High Steer Arms
- (1) Dana 60 Kingpin Component Kit
- Required Installation Hardware
Note: Optional 3.50" I.D. inner C's are available by request.

Tech Insight
What axle housings can this rear steer knuckle kit be used with?
The kit can be incorporated into GM 14-Bolt, Dana 60, Dana 70, Dana 80, fabricated 9" and 10", and other custom axle housings with compatible housing dimensions. This allows builders to use Dana 60 kingpin steering geometry without being limited to a Dana 60 center section.
What is the advantage of the interlocking high steer arm design?
The Crane Axle high steer arm uses precision-machined keyed engagement surfaces that mechanically interlock the steering arm with the knuckle. This helps transfer steering loads directly into the knuckle instead of relying solely on the clamping force of the mounting hardware.
Why use 8620 chromoly for a rear steer knuckle?
Rear steer systems used with large tires and aggressive off-road vehicles can place substantial impact and steering loads on the knuckles. The Crane Axle knuckles are cast and machined from 8620 chromoly steel for the strength and durability required in severe-duty steering applications.
Can I use common Dana 60 kingpin replacement components?
Yes. The system uses GM Dana 60 kingpin-style service components, helping make replacement parts easier to source and simplifying maintenance and trailside repairs.
What inner C bore is included with the kit?
The standard kit includes 3.00" I.D. inner C's. Optional 3.50" I.D. inner C's are available by request for builders working with different axle housing dimensions.
