Wilwood 120-16039 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 and high-performance applications. Designed for extreme durability in adverse conditions, this caliper features Thermlock® pistons that provide superior heat protection during intense braking situations.

Key Features:

• Stress-flow forged from premium grade aluminum alloy billet for superior strength
• Six piston design with Thermlock® pistons for ultimate heat resistance
• Radial mounting configuration for precise installation
• Compatible with rotors up to 15.00" diameter
• Multiple piston volume options to suit various braking requirements
• Forging process realigns internal grain structure for enhanced clamping efficiency
• Superior resistance to fatigue, stress, and distortion under heavy loads

The stress-flow forging process used in manufacturing the SX6R series body realigns the metal's internal grain structure to flow within the contour of the caliper body, eliminating the stresses and interruptions that occur when machining straight block billet. This results in a caliper with exceptional clamping efficiency and ultimate strength for demanding heavy-weight braking applications.
