Wilwood 120-13290-Y Aero6 Radial Mount 6-Piston Disc Brake Caliper Yellow

The Wilwood 120-13290-Y Aero6 is a forged six-piston radial mount disc brake caliper finished in a bright yellow anodized coating. Engineered for demanding street and track applications, this caliper delivers exceptional clamping force and precise modulation for heavy-duty braking requirements.

The Aero6 body is stress-flow forged from a premium-grade aluminum alloy billet. The stress-flow forging process realigns the metal's internal grain structure to follow the contour of the caliper body, eliminating the stress concentrations and grain interruptions that result from machining a straight-block billet. The result is a caliper with superior clamping efficiency and outstanding resistance to fatigue, distortion, and load-induced stress.

Key Features:

• Six-piston radial mount design for maximum braking performance
• Staggered piston bore sizes: 1.62 / 1.12 / 1.12 inch for optimized pad pressure distribution
• Compatible with 1.25-inch thick rotors, supporting rotor diameters from 12.88" to 15.00"
• Stress-flow forged premium aluminum alloy body for superior strength and fatigue resistance
• Internal fluid ports eliminate external cross-over tubes for a cleaner, more aerodynamic profile
• Yellow anodized finish for corrosion resistance and visual appeal
• Left-hand / right-hand orientation (L/H) — sold individually
• Made in the USA

The Aero6 incorporates race-proven technology into a versatile body design suitable for a wide range of high-performance street, competition, and custom brake system builds. Its radial mounting configuration and broad rotor diameter compatibility make it an ideal choice for heavyweight braking applications.
