The New Standard of Versatility

The Mack Keystone is built to handle demanding vocational tractor work. Designed with higher ground clearance and rugged construction, Keystone delivers the strength, maneuverability, and durability needed for unpredictable jobsites and heavy hauling applications.

Built to outwork the job.

Keystone features an all-new galvanized steel cab built to resist corrosion and withstand harsh environments. A construction-grade chassis and heavy-duty frame rails provide the strength required for extreme loads, while the available ImpactShield™ windshield helps extend service life with improved impact and scratch resistance.

Built to handle the terrain.

Higher ground clearance and rugged off-road capability allow Keystone to navigate rutted dirt roads and challenging terrain. Available Mack Command Steer improves handling while significantly reducing driver effort, and the MaxRide air suspension helps deliver a stable ride even on rough surfaces.

Safety that goes beyond the road.

The available Mack Protect Safety Suite uses radar and cameras to detect hazards and assist drivers when needed. Optional Digital Mirror System technology enhances visibility with camera-based mirrors, while available pedestrian detection alerts drivers to cyclists, motorcyclists, and pedestrians around the truck.
