Wilwood 120-13840 Forged Billet Dynalite Internal Disc Brake Caliper

The Wilwood Forged Billet Dynalite Internal represents the next generation enhancement of the proven Forged Dynalite series calipers. This high-performance disc brake caliper features an innovative single split bridge and spacerless design that maximizes structural strength while delivering a clean, race-inspired appearance.

Key Features:

• Stress-flow forged billet construction for superior strength-to-weight ratio
• Spacerless single split bridge design for enhanced rigidity and visual appeal
• FEA-generated radial transition design eliminates stress concentrations
• Forging process re-aligns metal grain structure within caliper contours
• Lightweight design starting at just 3.00 pounds
• Eliminates grain structure interruptions common in straight block billet machining
• Radiused transitions between piston housing and bridges increase deflection resistance

Performance Benefits:

The advanced forging process used in the Dynalite Internal caliper creates a continuous grain structure that follows the natural contours of the caliper body, delivering exceptional structural integrity. The FEA-optimized radial transitions between the piston housing and caliper bridges eliminate traditional steps and shoulders, substantially increasing resistance to deflection and caliper separation under heavy braking loads. Independent structural deflection and volume displacement testing has proven the Forged Dynalite Internal outperforms all existing calipers in this popular size class.

This caliper represents the strongest and stiffest design in the Dynalite family, making it an ideal choice for performance street, road race, and track day applications where maximum braking performance and reliability are essential.
