Wilwood 120-16890-BK Aero6 Forged Six-Piston Radial Mount Disc Brake Caliper Black

The Wilwood Aero6 (Part No. 120-16890-BK) is a forged six-piston radial mount disc brake caliper engineered to deliver heavy-duty stopping power for both street and track applications. Incorporating proven race technology into a design built for widespread adaptability, this caliper is a premium solution for high-performance and heavyweight braking demands.

Featuring internal fluid ports, the Aero6 eliminates the external fluid cross-over tubes and bulky center bridge assembly found on older designs, resulting in a cleaner, more rigid caliper body with improved structural integrity.

Key Features:

• Six-piston forged aluminum construction — stress-flow forged from premium-grade aluminum alloy billet for maximum strength and durability
• Stress-flow forging technology — realigns the metal's internal grain structure to follow the contour of the caliper body, eliminating machining-induced grain interruptions for superior fatigue resistance
• Radial mounting — provides precise, rigid caliper positioning for consistent brake feel and pad wear
• Compatible rotor diameter range: 12.88" to 15.00" — versatile fitment across a wide range of big brake applications
• Multiple piston volume options — allows tuning of brake bias and pedal feel to match specific vehicle requirements
• Black powdercoat finish — corrosion-resistant, high-temperature coating for a clean, durable appearance
• Sold individually

The Aero6's stress-flow forged body delivers superior clamping efficiency and ultimate resistance to fatigue, stress, and distortion under load — making it a trusted choice for performance builds requiring serious, repeatable braking performance.
