The TX6R big brake kit is made for trucks, SUVs, and armored vehicles. With 6-piston calipers and 15” to 16” rotors, the TX6R delivers superior stopping power and sustained high heat durability. Rear kits replace factory rotors but maintain OE parking brake assemblies. The kit is bolt-on ready and it is compatible with the original brake system output. All necessary hardware is included for installation.
