Wilwood 120-14441-BK Forged Four Piston Brake Caliper - Aero4-DS Black

The Wilwood Aero4-DS forged four piston caliper delivers heavy-duty stopping power for street and track applications. This radially-mounted caliper incorporates race-proven technology into a versatile body design with widespread adaptability. With multiple piston volume options and compatibility with rotor diameters ranging from 12.88" to 15.00", the Aero4-DS provides the flexibility needed to meet demanding braking requirements for heavy-weight vehicles.

Key Features:

• Stress-flow forged from premium grade aluminum alloy billet for superior strength
• Four piston design provides excellent clamping force and pedal feel
• Radial mounting configuration for enhanced structural rigidity
• Compatible with rotor diameters from 12.88" to 15.00"
• Black anodized finish for corrosion resistance and appearance
• Multiple piston volume options available for custom brake bias tuning

Advanced Manufacturing:

The Aero4 series body is stress-flow forged, a process that realigns the metal's internal grain structure to flow within the contour of the caliper body. This eliminates stresses and interruptions to the internal grain structure that occur when machining from a straight block billet, resulting in superior clamping efficiency and ultimate strength against fatigue, stresses, and distortion under load.

Ideal for road racing, track days, autocross, and high-performance street applications where reliable, fade-resistant braking performance is essential.
