Crane Axle GM/Dodge Dana 60 Knuckle Kit
CA01014C
Engineered for GM and Dodge kingpin Dana 60 front axles, the Crane Axle Interlocking Outer Knuckles with Stock Steering Provisions combine extreme 8620 chromoly strength with unmatched steering versatility. Cast and machined in the USA, these knuckles feature both OEM-style tie rod mounting locations and Crane’s precision-machined keyed interlocking top interface, allowing you to run factory low-steer setups, Y-link steering, crossover steering, or full high steer arm configurations on the same rugged platform.
Unlike traditional cast iron knuckles that crack under shock loading or rely entirely on fastener clamping force for high steer arms, Crane's keyed interlocking system mechanically transfers steering loads directly into the knuckle body. With a tensile strength of 97,000 PSI and yield strength of 57,000 PSI, this 8620 chromoly construction delivers outstanding impact resistance, fatigue life, and trail serviceability for rock crawlers, competition rigs, and heavy-duty axle builds.

Tech Insight
Why choose 8620 chromoly steel over factory cast iron? Standard cast iron knuckles are notoriously brittle and prone to cracking around the tie rod arms or top steering arm studs when subjected to shock loading from large tires and hydraulic steering. 8620 alloy chromoly steel features a higher carbon content than mild steel, creating an exceptionally hard, wear-resistant outer surface combined with a tough, ductile core that absorbs severe off-road impacts without fracturing.
Furthermore, by combining stock steering provisions with Crane's keyed interlocking box interface, this knuckle allows axle builders to run factory-location tie rods or Y-link steering today while leaving the upgrade path wide open for crossover steering or keyed high steer arms in the future—all with mechanical load transfer that eliminates bolt shear.
Frequently Asked Questions (FAQ)
1. What is the advantage of having stock steering provisions on an interlocking knuckle?
The OEM tie rod mounting provisions allow you to retain a stock low tie-rod location or a Y-link steering setup while still gaining the massive strength of an 8620 chromoly casting and the option to run a keyed high steer arm.
2. Can I use my factory tie rod and drag link with these knuckles?
Yes. The lower steering arm provisions are machined to match factory GM/Dodge tie rod end tapers and geometry, making them a direct bolt-on replacement for stock knuckles.
3. What is the difference between this kit and the standard Crane Interlocking Knuckle Kit?
The standard Crane Interlocking Knuckle is a dedicated high-steer knuckle without lower tie-rod arms. This version includes the lower OEM-style steering arms cast directly into the knuckle body for dual-purpose steering compatibility.
4. Do these knuckles work with Ford Dana 60 kingpin components?
No. GM/Dodge Dana 60 kingpin knuckles use a 6-bolt spindle bolt pattern and different brake caliper mounting dimensions compared to Ford Dana 60 axles, which use a 5-bolt spindle pattern.
5. What surface preparation is needed before installing and painting these bare steel knuckles?
Because these knuckles ship as bare unfinished steel, wipe them down thoroughly with solvent or brake cleaner to remove machining oils before applying primer, paint, or powder coating.
