Wilwood 120-13839-BK Forged Billet Dynalite Internal Disc Brake Caliper - Black

The Wilwood Forged Billet Dynalite Internal represents the next generation enhancement of the venerable Forged Dynalite series calipers. This high-performance disc brake caliper features an innovative single split bridge and spacerless design that enhances both structural strength and visual appeal, making it the stiffest and most visually pleasing design in the Forged Dynalite lineup.

Key Features:

• Stress-flow forged construction realigns metal grain structure within the caliper body contours for maximum strength
• Spacerless design eliminates weak points and enhances rigidity under braking loads
• FEA-generated radial transition design between piston housing and caliper bridges eliminates stress-concentrating steps and shoulders
• Lightweight construction with caliper weights starting at just 3.00 pounds
• Black anodized finish provides corrosion resistance and sleek appearance
• Proven to outperform existing styles through structural deflection and volume displacement testing

The stress-flow forging process provides a significant advantage over traditional machined billet calipers by eliminating breaks and interruptions to the internal grain structure that occur when machining from a straight block. The radius incorporated in the transition area between the piston housing body and caliper bridges substantially increases resistance to deflection and caliper separation under load, ensuring consistent brake performance even under extreme conditions.
