Strict Specification Control: Each front rear replacement kit undergoes rigorous dynamic balancing procedures before leaving the factory. This ensures responsive braking and stability during high-speed driving or emergency stops, reducing abnormal vibrations and wear. Improve braking performance significantly! Rust and Corrosion Resistance: The surface of the brake disc is treated with high-quality galvanization to prevent corrosion, enhancing durability and aesthetics effectively. Quick Heat Dissipation: The slotted and drilled brake rotors feature superior heat dissipation. Cool quickly under heavy loads or during emergency braking, preventing water and dust accumulation. Made from heavy-duty and durable HT250 cast iron, they resist deformation and provide reliable performance in various road conditions. Low Dust and Noise: The brake pads are primarily made of ceramic material, offering superior wear and fade resistance. These ceramic brake pads produce less dust during braking, and their chamfered design ensures a snug fit with the brake rotor, reducing noise. Vehicle Compatibility: Complete front and rear brake kit includes 2 front rotors, 2 rear rotors, 4 front brake pads, and 4 rear brake pads. The front rotor dia.: 13.8"/350 mm, and the rear rotor dia.: 13.7"/348.2 mm. Compatible with 2012-2014 Ford F-150 (6-Lug Models), 2015-2020 Ford F-150 (Models with Manual Parking Brake).
