Will these fit my vehicle's valve stems?

These are universal acorn-style caps designed for standard valve stems. Hand-tighten them onto your existing valves—if they spin freely without resistance, they'll seal properly.

Do I need any tools to install these?

No tools needed. Unscrew your old caps and hand-tighten these on. The knurled grip is designed to give you enough purchase to seal them snug without stripping.

Will the blue finish fade or chip?

The finish is applied to handle normal wheel exposure and temperature swings. Avoid aggressive brushing or solvents when cleaning your wheels to keep the color looking fresh longer.
