Wilwood 120-14862-RD SX6R Forged 6-Piston Radial Mount Disc Brake Caliper Red Right-Hand

The Wilwood SX6R is a forged six-piston radial mount disc brake caliper engineered to deliver serious stopping power for both street and track applications. Finished in Wilwood's signature red, the 120-14862-RD is the right-hand (R/H) version of Wilwood's largest and most capable radial mount caliper, designed to meet the most demanding heavy-duty braking requirements.

Key Features:

• Six-Piston Forged Design: Six pistons deliver even pad pressure distribution and maximum braking efficiency across the full rotor surface
• Stress-Flow Forged Aluminum Body: The caliper body is stress-flow forged from premium-grade aluminum alloy billet, realigning the metal's internal grain structure to follow the contour of the caliper — eliminating machining-induced stress interruptions for superior clamping efficiency and fatigue resistance
• Radial Mounting: Radial mount configuration maximizes caliper rigidity and thermal stability under high-load braking conditions
• Wide Rotor Compatibility: Supports rotor diameters up to 15.00 inches, providing flexibility across a range of heavy-duty performance and racing builds
• Multiple Piston Volume Options: Available in multiple piston configurations to fine-tune brake bias and pedal feel for specific applications
• Exclusive Dust Wiper Seal System: An innovative dust wiper seal protects pistons and bores from dust, debris, and corrosion — extending caliper life and satisfying environmental sealing requirements for street-registered use in applicable jurisdictions
• Red Anodized Finish: Wilwood's signature red powdercoat finish for a clean, high-performance appearance
• Right-Hand (R/H) Orientation: Designed for right-hand caliper mounting position

The SX6R's stress-flow forging process sets it apart from conventionally machined calipers. By realigning the aluminum's internal grain structure to flow with the caliper body's contour, Wilwood eliminates the structural weak points created by straight-billet machining — resulting in a caliper with greater strength against fatigue, stress, and distortion under extreme braking loads. Combined with its radial mounting geometry and six-piston clamping force, the SX6R delivers race-proven performance in a highly adaptable package suited to high-performance road builds, road racing, and track-day applications requiring maximum braking capacity.
