Description
High-Performance Rear Brake Kit. The Wilwood Tactical Extreme TX6R Rear Big Brake Kit features 15.50-inch slotted rotors and anodized clear six-piston calipers designed to deliver exceptional stopping power for trucks and SUVs, particularly in heavy-duty and tactical environments. This kit replaces factory rear brake components, providing consistent braking performance and enhanced durability under extreme heat conditions, making it an excellent upgrade for vehicles needing reliable rear braking enhancements.
_x000D__x000D_Construction and Appearance. The kit includes six-piston TX6R calipers finished with a durable Type III anodize coating to resist corrosion. The rotors are precision-machined from iron, finished with a black electro-coat, and feature a GT slotted design to improve cooling and help clear debris. The assembly also comprises iron parking brake hats with a black electro-coat finish, combining rugged durability with a professional look.
_x000D__x000D_Installation. Designed for a straightforward bolt-on installation using radial mount caliper brackets, this kit requires no drilling or modifications, simplifying the process. It is important to verify vehicle-specific wheel clearance to ensure proper fitment given the brake kit’s size and offset.
_x000D__x000D_Application. This rear brake kit is compatible with 2011-2019 Sierra 3500 HD models, fitting the OEM rear axle flange with zero axle offset. The kit maintains the use of the factory parking brake assembly for seamless integration.
