Wilwood 140-15382-R Tactical Extreme TX6R Rear Big Brake Kit Red Calipers

The Wilwood Tactical Extreme TX6R Rear Big Brake Kit delivers professional-grade stopping performance engineered for heavy-duty trucks, SUVs, and armored vehicles. This ready-to-bolt-on kit is purpose-built to handle extreme braking demands with consistent, reliable performance even under sustained high-heat conditions.

At the heart of this kit are TX6R radial mount six-piston calipers finished in a striking red powder coat. These forged aluminum alloy calipers are volume-matched to ensure full compatibility with the factory power brake system output, preserving your vehicle's original pedal feel and braking response. The calipers are fully compatible with the OE master cylinder, ABS system, and all electronic brake controls.

Paired with the calipers are massive 16.00" GT-60 directional vane Spec-37 alloy rotors. The Spec-37 iron alloy—originally developed for military applications—combined with the GT-60 curved vane design, provides exceptional heat dissipation and extreme-duty durability far beyond stock rotors.

This rear kit is designed to replace the factory disc brakes while retaining and integrating with the OE parking brake assembly, making it an ideal complement to front big brake upgrades. All necessary installation hardware and radial mount caliper brackets are included for a straightforward installation.
