Wilwood 120-13947 Forged Six-Piston Radial Mount Brake Caliper - GN6R

The Wilwood Grand National GN6R is a high-performance forged aluminum six-piston radial mount brake caliper designed for serious braking applications. Featuring a high-strength forged aluminum body, this caliper delivers exceptional rigidity and heat dissipation while minimizing unsprung weight.

Key Features:

• Forged aluminum construction for maximum strength-to-weight ratio
• Six-piston design provides excellent pad wear characteristics and consistent clamping force
• Radial mounting configuration for simplified installation and improved structural rigidity
• Compatible with rotors from 1.25" to 1.38" thickness
• Supports rotor diameters from 12.19" to 13.06"
• Available with hard-anodized or Quick-Silver nickel plate finish for corrosion resistance

The GN6R caliper is engineered for racing and high-performance street applications where stopping power, heat management, and durability are critical. The radial mount design allows for precise caliper positioning and reduces flex under extreme braking loads.
