Wilwood 120-17218-RD Radial Mount Brake Caliper Left Hand - XRS6R 6-Piston Red

The Wilwood 120-17218-RD XRS6R is a high-performance, 6-piston radial mount brake caliper designed for the left-hand (driver's side) position. Finished in Wilwood's signature red powdercoat, this caliper is purpose-built for demanding race and performance street applications where maximum stopping power and heat resistance are essential.

The XRS6R (Xtreme Race Series 6-Piston Radial) caliper is constructed from a high-strength forged aluminum body, delivering an exceptional strength-to-weight ratio. Radial mounting provides two planes of adjustment for precise rotor alignment and simplifies custom brake system adaptation across a wide range of vehicle platforms.

Key Features:

• 6-Piston Design: Progressive, differential-bore stainless steel pistons optimize pad loading and promote even pad wear across the full pad face
• Radial Mount: Simplifies installation and provides superior caliper-to-rotor alignment compared to traditional lug-mount designs
• Forged Aluminum Body: Lightweight and rigid construction minimizes caliper flex under hard braking for improved pedal feel and modulation
• Left-Hand Orientation: Specifically designed for the left side of the vehicle, ensuring bleeder screws remain properly positioned at the top for effective air bleeding
• Red Powdercoat Finish: Durable, high-temperature red finish provides corrosion resistance and a race-ready appearance behind the wheel
• High-Temperature Bore Seals: Engineered for positive piston retraction and long service life in hard-braking environments
• Recessed Bleed Screws: Two-piece bleed screws are recessed into the caliper body for protection against impact and debris damage

The Wilwood XRS6R caliper is an ideal upgrade for road racing, track day, and high-performance street builds where consistent, fade-resistant braking is required. Always verify correct rotor diameter and width compatibility when building your brake system.
