Wilwood 120-17213-BK Radial Mount Caliper Right-Hand - XRS6R 6-Piston Black

The Wilwood 120-17213-BK XRS6R is a right-hand, radial-mount 6-piston disc brake caliper finished in black powder coat. Engineered for extreme-duty street and track applications, the XRS6R is built to deliver maximum braking force with large-diameter rotors where thermal capacity and sustained stopping power are critical requirements.

Key Features:

• 6-Piston Design: Multi-piston configuration ensures even pad pressure distribution across the full rotor contact surface for consistent, fade-resistant braking performance
• Radial Mount Design: Radial mounting architecture maximizes caliper rigidity and reduces flex under hard braking loads for improved pedal feel and response
• Forged Aluminum Construction: High-strength forged aluminum body delivers an exceptional strength-to-weight ratio, keeping unsprung weight low without sacrificing durability
• Right-Hand Specific: Designed for right-side (passenger side) installation; sold as a single caliper
• Black Powder Coat Finish: Durable black powder coat provides corrosion resistance and a clean, aggressive appearance under the wheel
• Dust Wiper Seal System: Exclusive Wilwood dust wiper seals protect piston bores from debris and corrosion, extending service life and maintaining consistent piston travel
• Large Rotor Compatibility: Engineered for use with large-diameter, high-capacity rotors suited to performance street, road racing, and high-speed track applications

The XRS6R caliper is a purpose-built performance brake component from Wilwood Engineering, one of the most respected names in North American motorsport braking systems. Sold as a single caliper — order two for a complete axle. A custom bracket or application-specific adapter is required for installation. Compatible brake lines, fittings, and mounting hardware must be sourced separately.
