Dust Cap Aluminum Screw -in Billet

The WILWOOD Dust Cap Aluminum Screw-In Billet (MPN 270-9380) is a precision-engineered wheel hub dust cap designed to protect brake system components from dirt, moisture, and debris. Built from aluminum in a natural finish, this screw-in dust cap integrates seamlessly with WILWOOD brake systems and compatible wheel hub assemblies, delivering reliable protection in both street and performance driving applications where brake cleanliness directly impacts stopping power and component longevity.

The billet aluminum construction provides lightweight durability without sacrificing strength, a critical consideration in brake assembly design where added weight affects unsprung mass and thermal characteristics. The screw-in design ensures secure retention through standard hub threading, eliminating rattles and vibration-induced loosening during hard braking events. The natural aluminum finish resists corrosion while maintaining a clean appearance on aftermarket wheel packages, and the compact dimensions (5.25 x 1.1 x 6.65 inches) confirm compatibility with standard WILWOOD brake hub specifications without interference with wheel fitment or brake fluid lines.

This dust cap serves track enthusiasts, autocross competitors, and street performance builders who invest in quality brake systems and recognize that component protection directly affects system reliability and resale value. WILWOOD dust caps are frequently installed during brake system upgrades on street rods, muscle cars, and track-focused builds where exposed brake hardware is both functional and aesthetic. The lightweight aluminum (0.13 lbs) design makes it an ideal choice for builders minimizing unsprung weight while maintaining professional brake assembly appearance and environmental protection across multiple driving scenarios.
