Wilwood 120-14317-FSR Radial Mount Disc Brake Caliper Red - TC6R 6-Piston

The Wilwood TC6R Radial Mount Caliper is a next-generation big brake solution engineered for custom late-model trucks and sport utility vehicles. Built around a massive stress-flow forged aluminum body and six stainless steel pistons, the TC6R delivers exceptional clamping force, thermal resistance, and long-term durability under demanding load conditions.

Forged Aluminum Body Construction:

• Stress-flow forged from premium-grade billet aluminum alloy for maximum strength-to-weight ratio
• FEA (Finite Element Analysis) structural optimization minimizes weight while maximizing rigidity against deflection
• Expanded bridge radius accommodates rotors up to 1.38" thick and up to 16" in diameter
• Bridge joined and reinforced with six high-strength coated steel alloy bolts
• Cross-bridge bolts resist deflection and body separation under high pressure and heavy loads
• Steel insert plates protect bridge surfaces from wear and gouging caused by brake pad edges

Six-Piston Stainless Steel Piston Assembly:

• Piston bore configuration: 1.75" / 1.38" / 1.38" differential sizing derived from Wilwood racing caliper technology
• Thick-walled stainless steel pistons resist deflection and distortion under heavy braking loads
• Stainless construction reduces corrosion and limits heat transfer from pads to caliper body, seals, and brake fluid
• Differential bore design proportionately distributes clamping pressure for balanced pad loading and even wear at all temperatures
• Piston bore volumes matched for compatibility with OE master cylinder and power boost system output

Noise Reduction & Fluid Management:

• Rubber-dampened fluid transfer tubes reduce vibration transmission
• Recessed two-piece bleed screws for clean, reliable bleeding
• Bridge-mounted pad-dampening springs minimize road rattle, vibration, and brake squeal harmonics

Finish & Mounting:

• Multi-process gloss red coating for a high-tech, custom appearance inside the wheel
• Radial mount design accepts Wilwood adapter brackets for precise, secure attachment to factory spindle mount bosses
• Starting weight of 8.66 lbs for a strong power-to-weight ratio in a big brake package

The Wilwood 120-14317-FSR TC6R is an ideal upgrade for builders seeking serious braking performance, OE system compatibility, and standout style in a single forged caliper package.
