Wilwood 120-14317-RS TC 6R Radial Mount Disc Brake Caliper 6-Piston

The Wilwood TC 6R Radial Mount Caliper delivers next-generation big brake performance engineered specifically for custom late-model trucks and sport utility vehicles. This six-piston caliper combines massive stopping power with precision-forged construction to handle heavy loads while maintaining exceptional style and durability.

Premium Forged Construction:

• Stress flow forged from high-strength billet aluminum alloy for optimal weight-to-rigidity ratio
• FEA-optimized design minimizes weight while maximizing resistance to deflection
• Six high-strength coated steel alloy bridge bolts reinforce body integrity under extreme pressure
• Steel insert plates protect bridges from pad wear and gouging
• Starting weight of just 8.66 pounds

Advanced Six-Piston Design:

• Six thick-walled stainless steel pistons deliver superior clamping efficiency
• Differential bore sizing provides balanced pad loading and even wear across all temperatures
• Stainless steel construction resists corrosion and reduces heat transfer to seals and fluid
• Piston bore volumes matched to OE master cylinder and power boost system capacities

Performance Features:

• Expanded bridge radius accommodates rotors up to 1.38" thick and 16" diameter
• Rubber dampened fluid transfer tubes for vibration isolation
• Recessed two-piece bleed screws for clean installation
• Bridge-mounted pad dampening springs reduce road rattle, vibration, and brake squeal
