The Wilwood Forged Billet Dynalite Internal caliper, part number 120-13839-BK, is a performance disc brake caliper finished in black.

The Forged Billet Dynalite Internal is the next generation of Wilwood's long running Forged Dynalite series. The single split bridge and spacerless construction raise body stiffness over comparable earlier models, and the black finish keeps the caliper understated behind the wheel.

This caliper is identified by piston size and disc thickness rather than by a vehicle. The 1.38 inch bore is the smallest of the common Dynalite sizes and is often chosen for the rear axle or for lighter cars. Confirm bracket, rotor diameter, disc thickness, and mount spacing before ordering.
