A strong frame anchors the suspension, steering, and braking systems, providing confident handling whether the truck is empty or fully loaded. The available Off-Road Suspension Package on AT4 adds twin-tube Rancho® shocks and skid plates to absorb punishment on rough access roads, while the AT4X builds on that with a factory-installed 1.5-inch suspension lift, Multimatic® DSSV dampers, a rear electronic-locking differential, and larger protective plates. These upgrades help keep momentum and maintain traction over ruts, washouts, or sand. Trailering confidence is bolstered by features like the integrated Trailer Brake Controller, available ProGrade® Trailering System with In-Vehicle Trailering App, and up to 14 available camera views for positioning and monitoring. Steering and braking are tuned for reassuring feedback, with available Auto Grade Braking and Tow/Haul mode helping manage descents and maintain gear selection. For customers traveling frequently between job locations or farms across Manning and Marion, these mechanical systems work together to reduce fatigue, support stability in variable conditions, and inspire trust mile after demanding mile.
