Wilwood 120-17202-RD Radial Mount Caliper - XRS4R 4-Piston Red

The Wilwood 120-17202-RD XRS4R is a high-performance 4-piston radial-mount brake caliper finished in a striking red anodized coating. Engineered and manufactured by Wilwood Engineering, a leader in performance braking systems, the XRS4R is designed for demanding street and track applications where superior clamping force, heat resistance, and precise modulation are required.

The XRS4R caliper features a forged billet aluminum body that provides an exceptional strength-to-weight ratio, reducing unsprung weight without sacrificing structural rigidity. Its radial mounting design offers improved brake stiffness and more consistent pedal feel compared to conventional lug-mount calipers. The four-piston configuration ensures even pad wear and uniform clamping pressure across the full rotor contact surface.

Key Features:

• 4-Piston Design: Provides balanced, even clamping force across the brake pad for consistent stopping performance
• Radial Mount Configuration: Delivers greater caliper stiffness and improved brake response
• Forged Billet Aluminum Body: Lightweight yet extremely strong construction
• Red Anodized Finish: Durable, corrosion-resistant finish with a bold visual appearance
• High-Temperature Performance: Engineered to handle the heat generated during aggressive driving and track use
• Wilwood Quality: Designed, engineered, and assembled in the USA

The Wilwood XRS4R caliper is an ideal upgrade for performance enthusiasts looking to enhance braking capability with a proven, race-inspired component. Compatible with Wilwood's wide range of rotors, brackets, and brake pads for a complete custom brake system solution.
