Wilwood 120-16465 Forged Narrow Superlite Disc Brake Caliper - 4R

The Wilwood 120-16465 Forged Narrow Superlite 4R is a high-performance four-piston disc brake caliper engineered for racing and high-performance street applications. This caliper features an innovative complex-shaped forged billet body that removes unnecessary bulk while improving brake and fluid cooling and actually decreasing deflection under extreme braking loads.

Advanced Thermal Management:

• Four Thermlock® thermal barrier pistons significantly reduce heat transfer to the brake fluid, maintaining consistent pedal feel and preventing fluid fade
• Staggered bore design provides more even pad engagement and improved pad wear characteristics
• Complex body shape enhances airflow for superior cooling performance

Durability and Serviceability:

• Hard-anodized aluminum construction with Type III aluminum-oxide ceramic finish inside piston bores and on external surfaces for maximum durability and corrosion resistance
• Single-point bleed technology with low-profile bleed screws simplifies brake bleeding and routine maintenance
• No-bind pad retaining pins with spare included for reliable pad retention
• Accepts multiple 0.80-inch thick Wilwood race compound brake pads for extended service life and versatile applications

This radial-mount caliper combines race-proven technology with practical serviceability, making it an excellent choice for road racing, track day, and serious performance street builds.
