Wilwood 120-13839-RD Forged Billet Dynalite Internal Disc Brake Caliper - Red

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

Key Features:

• Stress-flow forged construction re-aligns metal grain structure within the caliper body contours, eliminating internal grain interruptions common in machined billet designs
• FEA-generated radial transition design eliminates steps and shoulders between piston housing and caliper bridges for maximum deflection resistance
• Spacerless single split bridge design provides the stiffest construction in the Forged Dynalite series
• Lightweight forged aluminum construction starting at just 3.00 pounds
• Superior resistance to caliper separation and structural deflection under heavy braking loads
• Internal piston configuration for improved clearance and fitment options
• Available in red finish for distinctive appearance

Structural deflection and volume displacement testing confirms the Forged Billet Dynalite Internal outperforms all existing calipers in this popular size class. The radial transition design substantially increases resistance to deflection by incorporating a radius between critical load-bearing areas. This makes it the strongest caliper available in its weight and size category.
