Yes, Jim, they made Quadrasteer pick-ups also. The pick-ups were made in both 1/2 and 3/4 ton versions. The Suburbans were only made in 3/4 ton as the Quadrasteer axle required a leaf spring rear suspension.
You can always spot a Quadrasteer by the marker lights forward and aft of the rear wheels. The rear track is over 80", requiring these marker lights.
