Wilwood 120-13842-P Forged Dynalite Internal Disc Brake Caliper Polished

The Wilwood 120-13842-P Forged Billet Dynalite Internal (FDLI) is the next-generation evolution of Wilwood's renowned Forged Dynalite caliper series. Engineered with a single split bridge and spacer-less design, this caliper delivers superior structural rigidity and a clean, visually striking appearance.

Key Features:

• Spacer-less design — the stiffest and most refined configuration in the Forged Dynalite lineup
• Stress-flow forging process re-aligns the metal's grain structure to follow the contour of the caliper body, eliminating the grain interruptions caused by machining straight billet stock
• FEA-generated radial transition design removes steps and shoulders between the piston housing and caliper bridges, substantially increasing resistance to deflection and caliper separation under load
• Starting weight of just 3.00 lbs — lightweight without sacrificing strength
• Polished finish for a premium, show-quality appearance
• Proven through structural deflection and volume displacement testing to outperform all existing styles in this popular caliper size class

The Wilwood FDLI caliper is the strongest caliper in its class, making it an ideal upgrade for high-performance street, track, and show car applications where both stopping power and aesthetics matter.
