Upgrade braking performance with the Wilwood 120-13845 Forged Dynalite Internal brake caliper. Designed for applications using a 13.06-inch outside-diameter rotor with a 1-inch rotor thickness, this four-piston caliper provides reliable clamping force and consistent performance for high-performance street, track, and competition vehicles. Its forged aluminum construction delivers strength while helping reduce unsprung weight.
The Wilwood Forged Dynalite Internal caliper features a 1.75-inch piston bore and a 5.250-inch lug-mount configuration for compatibility with properly matched braking systems. The internal bridge design supports a compact package while maintaining rigid caliper structure under braking loads. A gray anodized finish adds corrosion resistance and a clean, professional appearance.

Confirm piston sizing, mounting requirements, rotor specifications, and available wheel clearance before installation. Professional installation and complete brake-system testing are recommended to ensure proper fitment and safe operation.
