Wilwood 140-4258-B Forged Dynalite FDL Front Disc Brake Kit 10.75in Black

The Wilwood 140-4258-B Forged Dynalite (FDL) Pro-Series Front Brake Kit delivers a complete disc brake upgrade solution for Art Morrison strut applications. Designed for non-ABS spindle platforms found on American muscle cars, vintage street rods, and heavyweight drag cars, this kit provides serious stopping power in a bolt-on package.

At the heart of this kit is Wilwood's renowned forged billet Dynalite four-piston caliper finished in black anodize, mounted directly to the spindle via a bolt-on bracket. The 10.75-inch vented rotor provides excellent heat dissipation under demanding conditions, while the kit's compact design clears popular 15-inch wheels without modification.
