Wilwood 120-14437-RD FNSL6R Forged Narrow Superlite 6R Caliper Left Hand Red

The Wilwood Forged Narrow Superlite 6R Dust Seal (FNSL6R-DS) caliper represents the latest evolution of Wilwood's proven Superlite caliper series. This left-hand caliper features an exclusive wiper dust seal system that provides environmental protection for harsh conditions while delivering exceptional stopping power across a wide range of performance applications.

Premium Forged Construction:

Starting at just 4.9 pounds, the FNSL6R-DS body is stress-flow forged from premium aluminum alloy billets. This advanced forging process realigns the metal's internal grain structure to flow within the caliper body contours, eliminating the stresses and grain interruptions that occur with traditional billet machining. The result is superior strength and durability in an ultra-lightweight package, developed through computer-generated solid modeling and FEA stress analysis.

Advanced Six-Piston Design:

• Differential bore configuration provides balanced pad loading and even wear in sustained high-heat conditions
• One-piece stainless steel pistons offer slow heat transfer and exceptional corrosion resistance
• Optional Thermlock piston upgrade creates an efficient thermal barrier to reduce heat transfer to seals and fluid
• High-temperature square-faced bore seals maximize sealing area and provide controlled piston retraction

Enhanced Durability Features:

• SRS (Stainless Rotor Saver) bridge plates eliminate bridge wear from pad gouging and extend service life
• Spring-loaded SRS plates eliminate pad rattle and dampen vibrations that cause pad squeal
• Two-piece bleed screws on each end with internal fluid crossovers protect against track debris damage
• Integrated dust seal system provides environmental protection for challenging conditions

Compatible with the full range of Wilwood pad compounds to match brake response and heat requirements for any competition or high-performance driving application. Finished in red.
