Mack Trucks introduced two new vocational models ahead of CONEXPO-CON/AGG 2026: the redesigned Mack Granite and the new Mack Keystone Class 8 tractor.
The updated Granite features a new cab design and several safety technologies, including the Mack Protect system with cameras and radar sensors that provide 270-degree coverage around the truck. Additional safety features include an electronic park brake with rollaway protection, automatic emergency call capability and available side-curtain airbags.
The Granite will be offered in day cab and 44-inch sleeper configurations with axle-forward and axle-back options. Orders are expected to open in the second half of 2026, with production scheduled to begin in January 2027.

Mack also debuted the Keystone, a vocational tractor designed for both highway and off-road applications in industries such as construction, agriculture and logging. The truck features higher ground clearance, improved approach angles and a heavy-duty suspension system.
The Keystone will be available in day cab, 44-inch sleeper and 64-inch sleeper configurations with axle-forward and axle-back layouts. Rear axle options include 6x4, 8x4 and 8x6 configurations.
Orders for the Keystone are expected to open through Mack dealers in the third quarter of 2026.
