C/K Pickup models for 1997 are equipped with standard Electronic Variable Orifice (EVO) power steering.
EVO steering is an electronically controlled power steering system that improves steering ease at lower vehicle speeds (e.g., parking). At higher vehicle speeds, steering effort reverts to normal levels.
EVO is designed to provide a lower power steering fluid operating temperature which may help extend fluid life.
4WD K1500 models with Vortec engines benefit from shorter turning diameters for 1997. This is
an important feature for off-road enthusiasts who often maneuver their vehicles in limited spaces.
