Wilwood 120-16743 Forged Billet Dynalite Internal Disc Brake Caliper

The Wilwood Forged Billet Dynalite Internal/ST caliper is engineered specifically for high-temperature road racing applications on compact cars. Designed for rotors ranging from 11.00" to 12.19", this lightweight caliper features Thermlock® insulated pistons to maintain consistent performance under extreme heat conditions.

Key Features:

• Stress-flow forged construction realigns metal grain structure for maximum strength and durability
• Single split bridge with spacerless design enhances structural integrity and appearance
• FEA-generated radial transition design eliminates stress points between piston housing and bridges
• Thermlock® insulated pistons reduce heat transfer and maintain hydraulic fluid temperatures
• Lightweight design starting at 3.00 pounds
• Superior resistance to deflection and caliper separation under load compared to billet-machined alternatives

The stress-flow forging process used in manufacturing this caliper eliminates the grain structure interruptions common in straight block billet machining. Combined with radiused transitions in critical stress areas, the Forged Dynalite Internal delivers proven performance advantages in structural deflection and volume displacement testing, making it the strongest caliper in its class.
