Wilwood Forged Billet Dynalite Internal brake calipers are the next generation enhancement of the venerable Forged Dynalite Series calipers. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper's body. This removes the breaks and interruptions to the internal grain structure that occur when machining a straight block billet. The 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 substantially increases resistance to deflection and
Wilwood Forged Billet Dynalite Internal brake calipers are the next generation enhancement of the venerable Forged Dynalite Series calipers. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper's body. This removes the breaks and interruptions to the internal grain structure that occur when machining a straight block billet. The 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 substantially increases resistance to deflection and caliper separation under load. Structural deflection and volume displacement tests have proven the Forged Billet Dynalite Internal to outperform all existing styles in this caliper class.
