Wilwood 120-17459-BK AeroDM Forged Disc Brake Caliper - 6-Piston Black

The Wilwood 120-17459-BK AeroDM is a forged six-piston disc brake caliper engineered to deliver heavy-duty stopping power for street performance and off-road applications. Built on race-proven technology, the AeroDM integrates advanced caliper design with broad real-world adaptability, making it a top-tier upgrade for late-model trucks and demanding brake systems.

Variable Lug Geometry & Direct Spindle Mounting: The AeroDM's variable lug geometry enables direct spindle mounting compatibility with Wilwood's proprietary 13.38" diameter rotors across a wide range of late-model truck platforms. Multiple piston volume options allow the caliper to be tuned to virtually any heavy-weight braking requirement, whether for towing, off-road, or high-performance street use.

Stress-Flow Forged Aluminum Body: The Aero series caliper body is stress-flow forged from a premium-grade aluminum alloy billet. Unlike conventional machining from a straight-grain billet block, stress-flow forging realigns the metal's internal grain structure to follow the contour of the caliper body. This process eliminates internal stress points and grain interruptions, resulting in a caliper with superior clamping efficiency and exceptional resistance to fatigue, distortion, and deflection under load.

Internal Fluid Ports for Added Rigidity: The AeroDM is designed with internal fluid transfer ports, eliminating the need for external fluid crossover tubes and a bulky center bridge assembly. This not only cleans up the appearance but adds measurable structural rigidity to the caliper body.

Key Features:

• Six-piston forged aluminum caliper for maximum clamping force
• Stress-flow forged premium aluminum alloy body for superior strength and fatigue resistance
• Variable lug geometry for direct spindle mounting versatility
• Compatible with 13.38" diameter proprietary Wilwood rotors
• Internal fluid ports eliminate external crossover tubes for a cleaner, more rigid assembly
• Multiple piston volume options to match a wide range of braking demands
• Available in black powdercoat finish (suffix -BK)
• Designed for street performance and off-road heavy-duty applications

The Wilwood AeroDM 120-17459-BK is the ideal caliper upgrade for enthusiasts and builders who demand race-quality braking performance without sacrificing durability or versatility. Paired with the correct Wilwood rotor and brake pad, it forms the foundation of a complete high-performance brake system.
