Wilwood 140-17749 TX6R Tactical Extreme Rear Big Brake Kit

The Wilwood 140-17749 TX6R Tactical Extreme Big Brake Kit delivers professional-grade stopping power engineered specifically for trucks, SUVs, and armored vehicles. This rear disc brake upgrade combines extreme-duty components with bolt-on convenience for demanding applications.

Massive Six-Piston Calipers: The TX6R radial-mount calipers feature a forged aluminum body with stainless steel pistons, providing exceptional clamping force and heat resistance. The high-efficiency six-piston design distributes braking force evenly across the pad surface while maintaining a lighter weight than comparable cast iron designs.

Military-Grade Rotors: Features 15.00" to 16.00" diameter GT-60 directional vane rotors constructed from Spec-37 alloy iron, a material originally developed for military applications. The directional vane design maximizes heat dissipation under sustained high-heat conditions, ensuring consistent performance during heavy towing, hauling, or spirited driving.

OE System Compatible: Calipers are volume-matched to work seamlessly with original equipment power brake system output and ABS functions. This rear kit replaces factory disc brakes while utilizing the OE parking brake assembly as a complement to front big brake upgrades.

Complete Installation Kit: Includes radial-mount caliper brackets and all necessary hardware for a complete bolt-on installation. Note that braided stainless steel flex lines may need to be purchased separately depending on the specific application. Larger diameter wheels may be required for proper caliper clearance.

Designed for extreme duty cycle applications where sustained high-heat braking is required, this kit delivers the tactical-level performance that Wilwood's TX6R series is known for in professional and commercial vehicle applications.
