Wilwood 120-15598-BK Forged Four Piston Brake Caliper - Aero4-DS Black

The Wilwood Aero4-DS forged four piston brake caliper delivers heavy-duty stopping power for both street and track applications. Designed with race-proven technology and exceptional versatility, this caliper features radial mounting, multiple piston volume options, and compatibility with rotors ranging from 12.88" to 15.00" in diameter, making it ideal for high-performance braking requirements on heavy vehicles.

Key Features:

• Stress-flow forged construction from premium grade aluminum alloy billet for superior strength and durability
• Four piston design provides optimal clamping force and consistent brake pedal feel
• Radial mounting configuration for precise caliper alignment and improved structural rigidity
• Compatible with rotor diameters from 12.88" to 15.00"
• Multiple piston volume options to match specific braking performance requirements
• Black anodized finish for corrosion resistance and professional appearance
• Advanced forging process realigns internal grain structure to follow caliper contours, eliminating machining-induced stress points

The stress-flow forging process used in Aero series calipers provides superior clamping efficiency and ultimate resistance to fatigue, stress, and distortion under extreme braking loads. This manufacturing technique produces a caliper body that maintains structural integrity even during sustained high-temperature operation, making it an excellent choice for racing, towing, and heavy-duty applications.
