K-Frame

The K-frame was introduced during the development of the unitbody design, which design benefits of incorporating the chassis or frame into the body components. While forward and rear framerails protruded from the central cab, certain crossmembers were used to tie the exposed rails together. The K-Frame is both an engine cradle with motor mounts and the suspension's lower contol arms. The front spindles go between the lower control arms and upper A-arms which are mated to the inner fenderwells and forward framerails. The steering is then attached..

Factory K-frames were made from two pieces of stamped and molded heavy-gauge sheetmetal, spot-welded together into the characteristic "K" shape from which it got its name. Thick plates were welded on for the steering box perch and motor mounts.
