Wilwood 120-17220 XRS6R Left-Hand Radial Mount 6-Piston Brake Caliper Anodized

The Wilwood 120-17220 XRS6R is a left-hand (driver side), radial-mount, six-piston brake caliper finished in a durable anodized coating. Designed for high-performance racing and track-day applications, the XRS6R delivers exceptional clamping force, thermal management, and precise modulation under extreme braking conditions.

Built from a lightweight, high-strength forged aluminum body, the XRS6R caliper uses a symmetrical bridge design to distribute clamping loads evenly across the rotor contact surface. The radial mounting configuration provides superior rigidity and improved brake feel compared to conventional lug-mount designs, making it a preferred choice for purpose-built race cars and serious performance builds.

Key Features:

• Six-piston design for even pad wear and consistent, high-clamping braking force
• Radial (R) mount configuration for maximum caliper rigidity and improved pedal feel
• Left-hand (LH) orientation — driver side specific caliper
• Forged aluminum body — lightweight yet extremely strong under racing loads
• Anodized finish — corrosion-resistant hard anodize for long service life in demanding environments
• Stainless steel pistons — resist heat transfer to brake fluid to minimize fade
• Compatible with Wilwood XRS6R pad sets and radial-mount brake system components

The Wilwood XRS6R caliper is engineered for motorsport competitors who demand maximum stopping performance. Its radial mount design and six-piston configuration make it an ideal upgrade for dedicated racing applications where weight, stiffness, and brake force are critical.
