Wilwood 120-14489-BK FNSL6R Forged Narrow Superlite 6 Piston Caliper Right Black

The Wilwood Forged Narrow Superlite 6R Dust Seal (FNSL6R-DS) caliper combines race-proven stopping power with environmental protection for demanding brake applications. This right-hand caliper features an integrated wiper dust seal system, making it ideal for street, track, and off-road environments where debris and contamination are concerns.

Advanced Forged Construction:

Each caliper body is stress-flow forged from premium aluminum alloy billets using computer-generated solid modeling and FEA stress analysis. This forging process realigns the metal's internal grain structure to flow within the caliper's contours, creating exceptional strength while maintaining a lightweight 4.9-pound design. Stress-flow forging eliminates the internal stresses and grain interruptions that occur with traditional billet machining, resulting in the strongest possible aluminum caliper body.

Key Features:

• Six-piston differential bore configuration provides balanced pad loading and even wear in high-heat conditions
• One-piece stainless steel pistons offer superior corrosion resistance and slow heat transfer properties
• Compatible with Wilwood Thermlock pistons for enhanced thermal barrier performance
• SRS (Stainless Rotor Sleeves) bridge plates eliminate bridge wear from pad gouging and extend service life
• Spring-loaded SRS plates eliminate pad rattle and dampen harmonic vibrations that cause brake squeal
• Two-piece bleed screws on each end with internal fluid crossovers protect against track debris damage
• High-temperature square-faced bore seals maximize sealing area and provide controlled piston retraction
• Integrated dust seal system for environmental protection
• Finished in durable black coating

Compatible with Wilwood's complete range of performance brake pad compounds to match specific heat ranges and response characteristics for competition, high-performance street, and sports driving applications.
