Wilwood FDL Front Drag Race Brake Kits, Black, Drilled for 1971-78 Midsize

The Wilwood FDL Front Drag Race Brake Kit (Part #140-1013-BD) is a direct bolt-on setup designed for drag racing on 1971–78 midsize Ford vehicles and certain aftermarket front struts, covering both disc and drum spindles. The forged billet aluminium hubs and forged Dynalite four-piston callipers help trim over 30 pounds of weight from the front end compared to stock drums or disc brakes. The kit uses a solid, drilled steel rotor for reduced mass and better heat management. Hub assemblies are drilled for two common five-lug bolt patterns, providing wheel fitment flexibility. Every kit includes the required high-strength hardware, bearings, seals, and extra-length studs for a complete technical update. Installation is engineered for compatibility with factory spindle arrangements and emphasises straightforward maintenance and recurring part availability.
