The Crane Axle GM/Dodge Dana 60 Interlocking Knuckle Kit is designed for kingpin Dana 60 front axles used in rock crawlers, Ultra4 cars, competition buggies, and heavy-duty trail rigs. This kit combines 8620 chromoly outer knuckles, cast and machined in the USA, with Cranes keyed interlocking high steer arm system to improve steering rigidity and long-term durability under extreme use.
Unlike traditional steering arm designs that rely heavily on mounting fasteners alone, the Crane interlocking system transfers steering force directly into the knuckle body through precision-machined keyed engagement surfaces. This reduces stress on steering hardware while improving resistance to flex and steering arm movement during large tire loads and hydraulic steering use.

Tech Insight
The Crane Dana 60 Interlocking Knuckle Kit uses a patented keyed interlocking high steer arm system that transfers steering loads directly into the knuckle body rather than relying solely on steering arm bolts. Traditional Dana 60 steering arms depend heavily on clamping force from mounting hardware, which can loosen or fatigue under large tires, hydraulic steering systems, and aggressive off-road use. The interlocking design creates a stronger and more rigid steering assembly for rock crawlers, Ultra4 race cars, and rock bouncers.
Yes. The Crane Dana 60 Interlocking Knuckle Kit was specifically engineered to withstand the increased loads generated by full hydraulic steering and hydraulic assist steering systems. The 8620 chromoly construction and keyed steering arm engagement help reduce steering arm movement and hardware stress commonly encountered with large tires and double-ended steering cylinders.
This kit fits GM and Dodge kingpin Dana 60 front axles commonly found in Chevrolet K30, V30, Dodge W350, Dodge 3500, and many custom fabricated front axle builds. It is compatible with both factory kingpin Dana 60 inner C's and Crane Axle Dana 60 kingpin inner C assemblies. Always verify your axle is a kingpin Dana 60 before ordering.
A high steer Dana 60 setup improves steering linkage clearance by relocating tie rods and drag links higher on the axle. This helps protect steering components from rocks and trail obstacles while improving steering geometry on lifted vehicles. High steer systems are especially beneficial for rock crawlers, trail rigs, Ultra4 race cars, and rock bouncers running large tires and long-travel suspension systems.
Absolutely. Crane Dana 60 Interlocking Knuckles are cast and machined from 8620 chromoly steel in the USA and are designed for some of the harshest environments in off-road motorsports. They are commonly used on rock bouncers, Ultra4 cars, competition crawlers, and high-horsepower trail rigs where steering reliability and component strength are critical. The interlocking steering arm design was developed specifically to handle the shock loads and steering forces associated with extreme off-road driving.
