Description
The Wilwood Narrow Superlite 4R Front Brake Kit (part number 140-13880-R) is configured with 12.88 in Undrilled Rotors - Red Calipers. Application: 2007+ Jeep Wrangler.
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. The application-specific design accounts for original-equipment master-cylinder output and ABS operation where fitted. Retain the specified vehicle and brake configuration when evaluating compatibility. 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.
