Wilwood TX6R Rear Kit 15.50in Black 2011-2015 GM Truck/SUV 2500

Starting with the massive 15.50-inch diameter GT-60 directional vane rotors, forged from Wilwood's own Spec-37 alloy, this rear big brake kit is built for serious stopping power on your GM truck or SUV. These aren't just bigger rotors; they're designed to handle sustained high heat and extreme duty, offering consistent performance when you need it most. The TX6R radial mount six-piston calipers are volume-matched to work with your factory power brake system, ensuring a balanced feel and effective braking without requiring a master cylinder upgrade.

This kit replaces your factory rear disc brakes and is designed to integrate with your original equipment parking brake assembly, making it a complete upgrade. Wilwood includes the necessary radial mount caliper brackets and all the hardware to get this bolt-on kit installed. While this kit is designed for a direct fit, you may need to purchase braided stainless steel flex lines separately depending on your specific application. This upgrade is a popular choice for those looking to significantly improve braking performance on heavy-duty trucks and SUVs, especially when paired with a front big brake kit.
