Wilwood TX6R Big Brake Truck Front Brake Kit

Wilwood’s Tactical Xtreme TX6R Big Brake kits are the ultimate in braking performance for trucks, SUVs, and Armored Vehicles. Using TX6R radial mount six-piston calipers and massive 15.00” to 16.00” GT-60 directional vane Spec-37 alloy rotors, these kits deliver consistent stopping power and extreme duty durability under sustained high heat with this ready-to-bolt-on kit. The calipers are volume matched for compatibility with the original equipment power brake system output. Kits include radial mount caliper brackets and all the necessary hardware to complete the installation. Braided stainless steel flex lines will need to be purchased for some applications.
