Wilwood 120-13383-BK Narrow Superlite 6-Piston Brake Caliper Black

The Wilwood 120-13383-BK is a second-generation Narrow Superlite 6 (BNSL6) disc brake caliper featuring high-strength billet construction with internal crossover passages. This innovative design allows the caliper to mount in either front or rear spindle applications using the same part number, providing exceptional installation flexibility. The caliper is finished in a durable black powder coat.

Advanced Engineering and Construction:

• Computer-generated solid modeling and FEA stress analysis optimized design
• Lightweight yet durable construction starting at just 5.2 pounds
• Full-length stiffening ribs for maximum rigidity
• Closed-end bridge design delivers superior strength compared to open bridge calipers with minimal deflection under load
• Four high-strength steel end bridge bolts plus a fifth center bridge bolt for exceptional structural integrity
• Fifth center bolt allows easy pad access without caliper removal

Performance Features:

• Differential bore six-piston configuration provides balanced loading for even pad wear in high-heat environments
• One-piece stainless steel pistons offer slow heat transfer properties and excellent corrosion resistance
• SRS (Stainless Rotor Saver) bridge plates eliminate bridge wear from pad gouging and extend caliper service life
• Spring-loaded SRS plates prevent pad rattle and dampen harmonic vibrations that cause brake squeal
• Recessed two-piece bleed screws protected from track debris and damage
• High-temperature square-faced bore seals maximize sealing area and provide controlled piston retraction

Compatible with the full range of Wilwood pad compounds to match specific brake response requirements and heat ranges for competition and high-performance street applications.
