Want to add some shiny detail to your semi's front wheels? This SEPEY set includes two chrome-plated ABS plastic axle covers for the front hubs, plus 20 matching thread-on lug nut covers. The axle covers fit over a 33mm wheel hub. They're made from chrome-plated ABS plastic, so they look like chrome but won't rust like metal can. They just snap or press on over the axle hub to give it a clean, finished look. The lug nut covers screw directly onto your existing lug nuts (after you clean them) to cover them up. It's a simple cosmetic upgrade that makes your wheels look more personalized and maintained. Easy to install by hand – no special tools needed. Make sure your hub and lug nut sizes match (33mm) before ordering. A quick way to spruce up your rig's appearance.
