Description

Wilwood’s Tactical Extreme TX6R Big Brake rear kits are designed for Trucks, SUVs, and Armored Vehicles, offering superior stopping power and durability. These kits feature TX6R radial mount six-piston calipers and large 15.00” to 16.00” GT-60 directional vane Spec-37 alloy rotors. The calipers are volume-matched for compatibility with OEM power brake systems. TX6R rear kits replace factory disc brakes and retain the OE parking brake assembly, complementing front big brake upgrades. Kits include radial mount caliper brackets and all necessary installation hardware. Braided stainless steel flex lines may need to be purchased separately for some applications.
