Crane Axle GM/Dodge Dana 60 Interlocking Knuckle Kit

Why It’s the Best

The only Dana 60 outer knuckles on the market built from 8620 Chromoly Steel come from Crane Axle. Using weldable 8620 Chromoly Steel instead of cast iron allows for a lighter and stronger knuckle, engineered for extreme abuse.

Crane’s Interlocking High-Steer Arm Design eliminates the need for a 5th or 6th bolt for strength. Instead, the interlocking keys built into the knuckle increase structural rigidity. Each knuckle uses 9/16” hardware on the upper kingpin caps and steering arms, creating a rock-solid steering platform that won’t flex under load.

Why 8620 Chromoly Steel

8620 Alloy Steel has a much higher carbon content than mild steel, increasing overall tensile strength and durability.

Minimum Material Properties:

• Tensile Strength: 97,000 psi
• Yield Strength: 57,000 psi

The combination of a hard outer case and ductile inner core results in maximum resistance to wear and impact — meaning Crane 8620 Chromoly parts take more abuse, last longer, and outperform the competition.

100% American Made

Every Crane Axle product is cast, machined, and finished in the USA. Domestic casting ensures superior metallurgy, tighter tolerances, and consistent performance that imported products can’t match.

Engineered by Off-Road Professionals

At Crane Axle, off-road performance isn’t a department — it’s a lifestyle. Every component is engineered, tested, and abused by the same people who run them in competition. These knuckles are designed to survive the constant shock loads, torque spikes, and steering stress of real-world rock bouncing and Ultra4 racing.
