Wilwood 120-14320-RS TC Radial Mount Brake Caliper Rotor - 6R Rear 1.38 Left Hand Red

The Wilwood TC 6R Radial Mount Caliper represents a complete new generation of refinement in big brake technology. Engineered specifically for custom late model trucks and sport utility vehicles, this left-hand rear mount caliper combines six stainless steel pistons with a massive high-strength forged aluminum body to deliver exceptional stopping power and long-term durability.

Advanced Engineering and Construction:

• Stress flow forged from premium grade billet aluminum alloy blanks for superior strength-to-weight ratio
• FEA structural analysis optimizes rigidity while minimizing weight, starting at just 8.66 pounds
• Expanded bridge radius accommodates 1.38" thick rotors up to 16" in diameter
• Six high-strength coated steel alloy cross bridge bolts reinforce the body against deflection and separation under high pressure
• Steel insert plates protect bridges from wear and gouging caused by brake pad load bearing edges

Differential Piston Technology:

• Six thick-walled stainless steel pistons (1.88"/1.62" bore configuration) provide maximum clamping efficiency
• Stainless steel construction resists corrosion and reduces heat transfer to seals and brake fluid
• Differential bore design derived from Wilwood racing caliper technology distributes clamping pressure proportionately for balanced pad loading
• Even wear properties maintained across all loads and temperatures
• Piston bore volumes optimized for compatibility with OE master cylinder and power boost systems

Noise and Vibration Control:

• Bridge-mounted pad dampening springs reduce vibration, road rattle, and engagement harmonics that cause brake squeal
• Rubber dampened fluid transfer tubes minimize noise transmission
• Recessed two-piece bleed screws for easy maintenance

Specifications:

• Piston bores: 1.88" and 1.62" differential configuration
• Maximum rotor thickness: 1.38"
• Maximum rotor diameter: 16"
• Weight: 8.66 lbs (caliper only)
• Finish: Multi-process gloss red coating
• Mount style: Radial mount, left-hand, rear position

This caliper requires radial mount adapter brackets (available separately in Wilwood brake kits) for precise attachment to factory mount bosses on the original spindle. The special multi-process gloss red finish provides both corrosion protection and distinctive high-tech styling visible through wheel spokes.
