Fig. Fig. 1: View of the I-beam front suspension

Chevrolet and GMC vans from 1967-70 use an I-beam front axle with tapered leaf springs and a single shock absorber at each wheel. The I-beam is a conventional reverse Elliot type using solid kingpins and full-floating steering knuckle bushings. The front wheel spindles are cast integral with the steering knuckles.

A stabilizer (sway) bar is optional to minimize body lean and sway in curves. Heavy duty shock absorbers and springs have been optional on most models.
