Wilwood 120-16040 Forged Six Piston Radial Mount Brake Caliper - SX6R/ST

The Wilwood SX6R/ST forged six piston caliper delivers heavy-duty stopping power engineered for road racing applications. Designed for extreme performance, this caliper features Thermlock® pistons that provide superior heat protection and exceptional durability in the most demanding racing conditions.

Key Features:

• Stress-flow forged construction from premium grade aluminum alloy billet for superior strength and clamping efficiency
• Six piston design with Thermlock® heat-resistant pistons for consistent performance under extreme temperatures
• Radial mounting configuration for easy installation and optimal load distribution
• Compatible with rotors up to 15.00" diameter for versatile applications
• Multiple piston volume options available to tune brake bias and pedal feel
• Forging process realigns internal grain structure to eliminate stress concentrations and resist fatigue
• Enhanced resistance to caliper distortion under heavy braking loads

The advanced stress-flow forging process used in the SX6R series creates a caliper body that follows the natural contours of the design, resulting in superior strength compared to traditional machined billet calipers. This manufacturing method eliminates internal stresses and grain structure interruptions, delivering a caliper with ultimate clamping efficiency and long-term durability for professional road racing and heavy-duty braking applications.
