Wilwood 120-14440-BK Forged Four Piston Brake Caliper - Aero4-DS Black

The Wilwood Aero4-DS forged four piston caliper (120-14440-BK) delivers heavy-duty stopping power for both street and track applications. This high-performance disc brake caliper incorporates proven race technology into a versatile body design with widespread adaptability across multiple vehicle platforms.

Key Features:

• Stress-flow forged construction from premium grade aluminum alloy billet for superior strength and durability
• Four-piston design provides balanced, high-clamping force for consistent braking performance
• Radial mounting configuration for easy installation and optimal load distribution
• Compatible with rotor diameters ranging from 12.88" to 15.00"
• Multiple piston volume options to customize braking characteristics
• Black anodized finish for corrosion resistance and aggressive appearance
• DS (Dual-Side) configuration for enhanced thermal management

Advanced Manufacturing Process:

The Aero4 series body utilizes stress-flow forging technology that realigns the aluminum's internal grain structure to flow within the contour of the caliper body. This specialized process eliminates internal stresses and grain interruptions that occur with traditional straight block billet machining, resulting in a caliper with superior clamping efficiency, ultimate strength against fatigue, and exceptional resistance to distortion under extreme loads.

Ideal for heavy-weight vehicles requiring maximum braking performance, the Aero4-DS caliper is engineered to handle demanding road and track conditions while maintaining consistent pedal feel and stopping power.
