Wilwood 120-17214 XRS6R 6-Piston Radial Mount Caliper Left Hand Anodized

The Wilwood 120-17214 XRS6R Left-Hand Radial Mount Caliper is a high-performance, 6-piston fixed caliper engineered for demanding road racing, track day, and performance street applications. Finished in a durable hard anodized coating, this caliper delivers excellent corrosion resistance and a clean, motorsport-ready appearance that stands up to the heat and abuse of serious braking use.

The XRS6R features a radial (axial) mounting configuration, which provides a more rigid caliper-to-upright interface compared to traditional lug-mount designs — reducing flex under heavy braking loads and delivering more consistent pedal feel and pad wear. The six-piston design ensures even clamping force distribution across the full pad surface for maximum stopping power and improved modulation.

Key Features:

• 6-piston fixed caliper design for superior braking force and modulation
• Radial mount configuration for increased rigidity and reduced caliper flex
• Hard anodized finish for corrosion resistance and long-lasting durability
• Left-hand (driver side) caliper — sold individually
• Forged aluminum body construction for an optimal strength-to-weight ratio
• Compatible with Wilwood's wide range of radial mount brackets and rotors
• Designed for high-temperature racing and performance street brake applications

Built by Wilwood Engineering, a leader in high-performance disc brake technology since 1977, the XRS6R caliper is part of a comprehensive brake system lineup trusted by professional and amateur motorsport competitors alike. This caliper is sold as a single unit — order the matching right-hand caliper for a complete axle installation.
