Product Description

The Wilwood 140-18205R is the TX6R Tactical Extreme Front Big Brake Kit for the 2021-2025 Ford F-150 in Red, featuring 15.50-inch GT-72 staggered-vane slotted Spec-37 alloy rotors paired with six-piston TX6R radial-mount calipers. Engineered for severe duty applications -- towing, hauling, off-road, and armored vehicle use -- these kits deliver consistent stopping power and extreme duty durability under sustained high-heat braking conditions. The forged aluminum TX6R calipers are volume-matched to maintain compatibility with the factory power brake system and electronic brake controls, while providing dramatically increased clamping force and thermal capacity over the OE setup.

Requires a minimum 20-inch wheel diameter for proper clearance. Direct bolt-on installation to factory disc spindles -- no modifications required. The "-R" suffix designates Red powder coat finish; black version is 140-18205. Made in the USA by Wilwood Engineering. Backed by Wilwood's warranty.
