The sophisticated Autoride suspension system automatically stiffens shock absorber damping when needed to control wheel motion. The automatic rear air-assisted load leveling shock absorbers help maintain vehicle height when fully loaded. The overall result is enhanced control, a high load-carrying capacity and a remarkably comfortable ride.
