Wilwood 120-14445-BK Aero6-DS Left-Hand 6-Piston Forged Aluminum Disc Brake Caliper - Black

The Wilwood Aero6-DS is a radial-mount, six-piston forged aluminum brake caliper engineered for serious road and track applications. Part number 120-14445-BK is the left-hand (driver-side) version, finished in a durable black powder coat. With compatibility across rotor diameters ranging from 12.88" to 15.00" and multiple piston volume options, the Aero6-DS delivers the versatility to meet demanding heavy-weight braking requirements on a wide range of performance builds.

Key Features:

• Six-Piston Design: Provides exceptional clamping force and even pad wear across the full face of the brake rotor
• Stress-Flow Forged Aluminum Body: The caliper body is forged from a premium-grade aluminum alloy billet using a stress-flow process that realigns the metal's internal grain structure to follow the contour of the caliper — eliminating the structural weaknesses caused by machining a straight-grain billet
• Superior Strength and Fatigue Resistance: The stress-flow forging process results in a caliper body with outstanding clamping efficiency and enhanced resistance to fatigue, stress, and distortion under heavy load
• Radial Mounting: Provides a more rigid, precise connection to the upright or spindle compared to lug-mount designs, improving brake feel and pedal response
• Multiple Piston Volume Options: Allows fine-tuning of brake bias and pedal feel to suit specific vehicle and driver preferences
• Wide Rotor Diameter Range: Compatible with rotors from 12.88" up to 15.00" in diameter, making this caliper suitable for a broad range of performance and race applications
• Left-Hand (Driver-Side) Application: This is the designated left-hand caliper in a matched Aero6-DS brake system
• Black Powder Coat Finish: Provides corrosion resistance and a clean, aggressive appearance under the wheel

The Wilwood Aero6-DS caliper is a purpose-built braking component for enthusiasts and racers who demand consistent, fade-resistant stopping power. Its forged construction and radial-mount architecture make it a top choice for high-performance street machines, dedicated track cars, and heavy-duty motorsport builds where brake integrity under sustained load is critical.
