Construction & Design

The Wilwood Narrow Superlite calipers are forged from high-strength aluminum alloy, striking an optimal balance between durability and weight savings. Their red powder-coated finish not only protects against corrosion but also provides a standout look behind your wheels. The 14-inch rotors are precision-machined from premium-grade cast iron and feature drilled holes to optimize cooling and minimize brake fade during demanding driving scenarios.

The radial mount caliper design enhances structural rigidity, resulting in improved pedal feel and braking efficiency. Engineered for direct bolt-on installation, this kit uses factory disc spindles and mounting points, ensuring a seamless upgrade that maintains the integrity of your Jeep’s original braking system.

This preserves the vehicle’s original ABS and master cylinder functions, ensuring safety and reliability remain uncompromised. Installation involves replacing the front rotors and calipers and bleeding the brake system to achieve optimal performance.

Note that wheels with a minimum diameter of 18 inches are required to provide proper clearance for the larger rotors and calipers included in this kit.
