The Wilwood Tactical Extreme TX6R front big brake kit for 2004–2008 Ford F-150 4WD applications uses radial-mount six-piston TX6R calipers matched to massive GT-60 Spec-37 alloy rotors (15.00"–16.00") for sustained stopping power under heavy-duty use. Kits include radial-mount brackets and hardware and are volume-matched for compatibility with OE power brake systems; braided stainless flex lines may be required for some installs.
