Crane's Extreme Duty Interlocking outer knuckles are made from Hi Strength Nodular Iron. The interlocking design is a Crane original! You can say goodbye to broken hi-steer arm studs now that the interlocking key is carrying the load. They are made to be used with Crane Interlocking Hi-Steer Arms.
Crane's outer knuckle kits: GM, Ford, Dodge, CJ, and Fullsize Jeep Dana 44 and GM 10 bolt front axles from 1/4 ton to 3/4 ton. Most applications are direct bolt on replacements. Some may require caliper bracket, spindle, and caliper changes.
Proudly Made In the U.S.A.
