Wilwood 120-13843-BK Forged Dynalite Caliper Black 1.75" Pistons .38" Disc

The Wilwood Forged Billet Dynalite Internal represents the next generation enhancement of the legendary Forged Dynalite series brake calipers. This single-piston caliper features a revolutionary spacer-less design with a single split bridge configuration that enhances both structural rigidity and visual appeal. Designed for .38" thick rotors with 1.75" pistons, this caliper delivers exceptional stopping power in a lightweight, high-strength package.

Key Features:

• Stress-flow forged billet construction realigns metal grain structure for maximum strength
• Spacer-less single split bridge design eliminates weak points and improves aesthetics
• FEA-generated radial transition design between piston housing and bridges resists deflection
• Weighs approximately 3.00 pounds—strongest caliper in its class
• Black anodized finish for corrosion resistance and aggressive appearance
• 1.75" diameter pistons provide optimal clamping force
• Accepts .38" thick brake rotors

The stress-flow forging process creates superior strength by aligning the metal's grain structure to follow the contour of the caliper body, eliminating the structural interruptions that occur when machining from straight billet. The radius transition areas substantially increase resistance to deflection and caliper separation under heavy braking loads. Structural deflection and volume displacement testing confirms the Forged Dynalite Internal outperforms all existing calipers in this popular size class.
