Wilwood 1999-2010 GM H2/2500 TX6R Big Brake Truck Front Brake Kit

Upgrade the front braking system of your compatible 1999-2010 GM H2/2500 Series truck or SUV with the Wilwood TX6R Big Brake Truck Front Brake Kit. Designed for heavy-duty truck and SUV applications, this extreme-duty front brake system combines Wilwood TX6R six-piston radial-mount calipers with massive 16.00-inch GT Slotted rotors for increased braking capacity, heat management, and consistent stopping performance.

Wilwood's Tactical Extreme TX6R Big Brake systems are engineered for demanding truck, SUV, and heavy-duty vehicle applications. The TX6R six-piston calipers are volume matched for compatibility with the original equipment power brake system output, while the large GT-60 directional-vane Spec-37 alloy rotors provide the thermal capacity needed for sustained high-temperature braking.

The 140-13877 family uses 16.00-inch GT Slotted rotors across all three configurations and is available with Black Powder Coat, Anodize, or Red Powder Coat calipers.
