Screw On Hubcap

The Screw On Hubcap from WILWOOD is a essential brake system accessory designed for vehicles equipped with high-performance disc brake kits. As a mechanic who regularly builds custom brake systems, this hubcap serves a critical protective function—it shields the brake caliper, rotor assembly, and wheel components from road debris, moisture, and contamination that can compromise stopping power and component longevity. Whether you're running a street performance setup or a dedicated track car, proper caliper and rotor protection directly impacts brake fade resistance and maintenance intervals.

This screw-on design utilizes a threaded attachment method that ensures secure, vibration-resistant mounting—critical when braking forces generate significant mechanical stress at the wheel interface. The compact profile (5.25 x 1.15 x 6.65 inches) and lightweight construction (0.21 lbs) minimize unsprung mass while maintaining structural integrity. The threaded fastening system allows for quick removal during brake service without requiring special tools, a practical consideration when you're performing routine caliper maintenance, pad changes, or rotor inspections. WILWOOD's engineering ensures the hubcap won't rattle or shift under hard braking or cornering loads.

This hubcap is ideal for builders and enthusiasts running WILWOOD brake kits on street cars, road course vehicles, or weekend track builds where brake protection and system accessibility matter equally. Installation is straightforward—simply screw the cap onto the threaded mounting point until hand-tight, then verify seating with a quarter-turn. Compatibility depends on your specific WILWOOD brake caliper model and wheel offset; measure your current brake assembly before ordering to confirm fitment. Regular cleaning of the hubcap maintains visibility of brake fluid condition and prevents corrosion buildup on the caliper body.
