Construction & Design

The Z36 Big Brake Conversion Kit features rotors crafted from premium-grade materials with a zinc coating that resists rust and corrosion, ensuring long-lasting durability even in harsh off-road environments. The drilled and slotted rotor design improves ventilation and helps evacuate brake dust and gases, maintaining consistent braking performance during heavy use.

PowerStop’s heavy-duty caliper brackets are precision-engineered to provide a secure mounting platform for the larger rotors, maintaining proper alignment and minimizing flex under braking loads. The carbon fiber ceramic friction compound in the Z36 Extreme Truck and Tow brake pads offers a balanced blend of stopping power, low noise, and minimal dust generation, making it suitable for both daily driving and demanding trail conditions.
