Description
The Wilwood TX6R Rear Brake Kit (part number 140-13874) is configured with 15.50 in Rotors - Black Calipers. Application: 2011-2015 GM Truck/SUV 2500.
The radial-mount caliper arrangement uses a dedicated bracket to establish caliper position over the rotor. Bracket geometry and rotor offset are therefore part of the fitment specification. This application retains the original-equipment parking brake arrangement; confirm that the required components are present and serviceable. The rotor configuration and caliper finish shown here identify this specific part number. Match the required axle, spindle, mounting arrangement, and any listed offset to the vehicle’s installed components.
