Wilwood 120-14490-RD FNSL6R Forged Narrow Superlite 6R Left Front Caliper with Dust Seal - Red

The Wilwood 120-14490-RD Forged Narrow Superlite 6R Dust Seal (FNSL6R-DS) caliper combines high-performance braking with environmental protection for demanding applications. This left-hand, red-anodized caliper features an exclusive wiper dust seal system, making it ideal for racing and street environments where dirt, debris, and moisture protection are essential.

Advanced Forged Construction:

Each caliper body is stress-flow forged from premium aluminum alloy billets, starting at just 4.9 pounds. This specialized forging process re-aligns the metal's internal grain structure to flow within the caliper body contours, creating superior strength compared to conventional machined billet designs. Computer-generated solid modeling and FEA stress analysis ensure optimal material distribution and durability.

Six-Piston Differential Bore Design:

• Unique differential bore configuration provides balanced pad loading for even wear
• One-piece stainless steel pistons resist corrosion and slow heat transfer
• Optional Thermlock piston upgrade available for enhanced thermal barrier protection
• Reduced heat transfer to caliper body, seals, and brake fluid extends component life

Professional-Grade Features:

• SRS (Stainless Rotor Saver) bridge plates eliminate pad gouging and bridge wear
• Spring-loaded SRS plates prevent pad rattle and reduce harmonic vibrations
• Two-piece bleed screws on each end for easy bleeding and debris protection
• Internal fluid crossovers protect against track debris damage
• High-temperature square-faced bore seals maximize sealing area and provide controlled piston retraction
• Exclusive wiper dust seal system for environmental protection

Compatible with the full range of Wilwood brake pad compounds, allowing you to match brake response and heat range to your specific competition or high-performance street driving needs. This left-hand caliper is designed for extreme environments where maximum stopping power and reliability are non-negotiable.
