This translates to absolute stability when your family is navigating slick winter commuting routes or unplowed access roads.

Standard SUVs cannot survive deep ruts or jagged terrain. The Yukon AT4 features a specialized front fascia that drastically improves clearance, resulting in a 32-degree approach angle. This means you can drive up steep inclines without tearing off your front bumper.
The vehicle also features heavy-duty steel front skid plates. This physical armor deflects rocks away from your oil pan and drivetrain, preventing catastrophic mechanical damage when you take your vehicle off the pavement near Mississinewa Lake.
