Wilwood 140-18156 is an AERO6 big front brake kit designed for Chevrolet and GMC applications using factory disc spindles. This setup is intended for heavy-duty braking situations, including towing, off-road use, and aggressive street driving where larger brake capacity and improved cooling are critical.

The kit features black powder-coated six-piston AERO6 calipers and 14.00-inch GT slotted curved-vane rotors for strong, repeatable stopping power under sustained heat. It is a premium front brake solution for builders wanting both functional performance and a high-end custom look.

Specs

Our rotors are machined and fully e-coated, just like the rotor hats. This is a protectant coating the prohibits surface rust from forming on the exposed surfaces. Once the parts are installed and being bedded in, the brake pad friction and caliper pressure will remove the coating at the spot the brake pads touch. This will expose the silver iron material underneath.
