Many of the chassis components were the same as the first generation (the control arms between the first and second generation were the same, originally sourced from GM's G-body platform), along with the steering knuckle, leaf springs, and differential assembly but suspension and axles were greatly enhanced. Lower control arms for the two-wheel drive model had 1/4-inch thicker steering stops - the second generation control arms are commonly used as an upgrade for the first generation. Sport utility models (Blazer, Jimmy, Bravada) came with thicker front and rear sway bars.
