Wilwood 120-13844-P Forged Dynalite Internal Brake Caliper - 4-Piston Polished

The Wilwood Forged Billet Dynalite Internal represents the next generation enhancement of the venerable Forged Dynalite series calipers. Designed with a single split bridge and spacerless design to enhance strength and appearance, this polished aluminum caliper delivers exceptional performance for high-performance street and racing applications.

Advanced Engineering and Construction:

• The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper body, eliminating the breaks and interruptions to the internal grain structure that occur when machining a straight block billet
• FEA generated radial transition design eliminates steps and shoulders in the area between the piston housing body and the caliper bridges
• Incorporating a radius in this transition area makes it extensively more resistant to deflection and caliper separation under load
• The Forged Billet Dynalite Internal is the strongest caliper in the class, with weights starting at 3.00 pounds

Key Specifications:

• Four-piston design for balanced braking force
• Piston diameter: 1.75 inches (44.5mm)
• Rotor thickness: 0.81 inches (20.6mm)
• Forged billet aluminum construction
• Polished finish for premium appearance
• Universal fit with semi-universal mounting

Structural deflection and volume displacement tests have proven the Forged Dynalite to outperform all existing styles of this popular caliper size. The spacerless single-piece bridge design enhances both rigidity and visual appeal, making this an ideal upgrade for custom brake systems requiring maximum performance and show-quality aesthetics.
