How Does the Max Trailering Package Improve Towing Capacity?

The GMC Max Trailering Package increases how much weight a truck can tow and makes heavy loads safer to handle. By adding factory upgrades, it helps Sierra 1500, Sierra 2500, and Sierra 3500 models work at their full potential.

What makes towing easier and safer?

The package raises both Gross Vehicle Weight Rating (GVWR) and Gross Combination Weight Rating (GCWR). This means the truck can pull more weight without strain. It also improves control on steep grades, wet roads, or long highway drives.

Key features that boost towing include:

• GMC trailer brake controller for precise trailer braking.
• Enhanced cooling to keep the engine running strong under load.
• Revised axle ratio to provide more torque and pulling power.
• Sierra Max Trailering upgrades to suspension and springs for better stability.

Why does this matter?

When properly equipped, Max Trailering towing capacity can climb to impressive numbers:
