Wilwood 2021-2025 F-150 TX6R Big Brake Truck Front Brake Kit

Upgrade the front braking performance of your 2021-2025 Ford F-150 with the Wilwood Tactical Extreme TX6R Big Brake Truck Front Brake Kit. Designed for demanding truck applications, this system combines Wilwood's TX6R six-piston radial-mount calipers with massive 15.50-inch GT-60 directional-vane Spec-37 rotors to deliver increased braking capacity, excellent heat management and consistent stopping performance under sustained high-temperature conditions.

The TX6R system is engineered for trucks that require additional braking capability for performance driving, towing, hauling and extreme-duty use. The six-piston calipers are volume matched for compatibility with the factory power brake system output, while the large directional-vane rotors provide the thermal capacity required for repeated heavy braking. This application is designed for 2021-2025 F-150 models with 6-lug hubs and includes application-specific flexlines.
