Construction & Design

The Wilwood Narrow Superlite calipers are forged from high-strength aluminum alloy, offering an optimal balance of lightweight construction and structural rigidity. This design reduces unsprung weight, improving suspension response and overall vehicle handling. The six-piston configuration applies even pressure across the brake pads, enhancing braking force and pedal feel.

The rotors feature a slotted design that helps evacuate gases, dust, and water from the braking surface, maintaining consistent friction and reducing the risk of brake fade during aggressive driving or off-road conditions. The black powder-coated calipers provide long-lasting corrosion resistance while complementing the rugged aesthetic of the Jeep Wrangler JK.
