Wilwood 120-13826 Forged Superlite 4R Right Hand Brake Caliper

The Wilwood Forged Superlite 4R (FSL4R) caliper represents the benchmark in high-performance disc brake technology for asphalt short track, late model, modified, and open wheel competition. This right-hand caliper also excels in road-race, rally, and sport driving applications where weight savings and exceptional strength are critical.

Key Features:

• Stress-flow forged from premium grade aluminum alloy billet for maximum strength-to-weight ratio
• Lightweight design at just 4.4 pounds assembled weight
• Internal fluid ports eliminate external crossover tubes for cleaner installation and reduced failure points
• Computer-generated solid modeling and stress analysis optimized body design
• Closed end bridges with radial transition to main body reduces stress concentration
• Enhanced resistance to deflection under high brake loads
• Anodized finish for corrosion resistance and professional appearance

The FSL4R caliper body eliminates machined steps and sharp shoulders in critical stress areas, providing measurably increased overall body strength compared to conventional designs. The advanced forging process and engineering make this caliper ideal for demanding racing applications where consistent brake performance and durability are essential.
