2016 Mack Granite GU713

The 2016 Mack Granite GU713 is a tri-axle dump truck built for heavy-duty hauling. It runs the MP7 or MP8 engine, carries a legal payload of 16–18 tons depending on configuration, and holds its value well in the used market — typically between $60,000 and $110,000 depending on spec, mileage, and condition.

The GU713 is one of the most recognizable vocational trucks on the road. It was built for the job site, not the highway — granite, asphalt, aggregate, fill dirt. If you need a tri-axle that can handle repetitive heavy loads without major drivetrain surprises, this is a proven option. But not every unit is worth buying. Here's what separates the good deals from the expensive mistakes.

What are the key specs of the 2016 Mack Granite GU713 Tri Axle?

The GU713 designation tells you the cab and chassis configuration. Paired with a tri-axle setup, you're looking at:

• Engine: Mack MP7 (345–425hp) or MP8 (415–505hp)
• Transmission: Mack mDrive automated manual or Allison/Fuller manual options
• GVWR: Up to 60,000 lbs in tri-axle configuration
• Rear axles: Mack single-reduction or dual-reduction depending on spec
• Suspension: Spring or air-ride rear — confirm before you buy
• Body: Steel or aluminum dump, typically 14–16 ft

Engine choice matters for your application. The MP8 gives you more pulling power for heavy haul. The MP7 costs less to maintain over time in lighter-duty cycles. Know your average payload before you prioritize horsepower.

Why do buyers choose the 2016 Mack Granite GU713 over competitors?

The GU713 competes directly with the Kenworth T800, Peterbilt 367, and Volvo VHD in the vocational dump segment. Here's the real-world breakdown:

• Mack GU713 vs. Kenworth T800: The T800 has a larger dealer network for parts. The GU713 has better factory vocational spec options out of the plant — Mack designed the Granite for job-site durability from the ground up.
• Mack GU713 vs. Peterbilt 367: The 367 rides better on the highway. The GU713 holds up better in high-cycle dump operations. If you're running quarry or construction, the Granite wins.
• Resale: Mack Granites hold value well in the tri-axle market, particularly in the Northeast and Southeast U.S. where aggregate hauling demand stays strong.

Is a 2016 Mack GU713 a good investment for a small fleet or owner-operator?

For an owner-operator, the GU713 is a strong buy — if the unit is clean. Maintenance costs are predictable on MP-series engines. Parts availability is solid. And tri-axle dump capacity keeps you competitive for DOT-regulated haul jobs without needing a four-axle setup.

For a small fleet, buy units with matching transmissions and axle configurations. Mixing mDrive and manual units across your fleet complicates driver assignments and parts stocking.

Verify emissions compliance for your state before you buy. Some states require active DPF regeneration systems to be fully functional for registration.

Browse current listings, get the VIN, and run a pre-purchase inspection before you sign anything.
