JIANXIAOGUO 8" Chrome Dome Hub Caps Set of 4 – 8-1/2" Axle Fit, Baby-Moon Style, Corrosion-Resistant

These are four 8-inch chrome-plated dome hub caps by JIANXIAOGUO designed to protect and dress the rear axles of semi trucks such as Peterbilt and Freightliner.

Upgrade the look and durability of your truck's rear wheels with a set of four 8" dome-style hub caps. Constructed from chrome-plated steel, these hub covers resist corrosion and wear better than plain metal options while providing a polished, classic baby-moon appearance. They’re built to fit hubs with an 8-1/2" axle diameter and eight 5/8" inner studs, and include a 1" sidewall and approximately 3-1/2" overall height for a secure, finished fit.

How do these hub caps improve my truck's appearance and maintenance?

The shiny dome shape delivers a clean, retro look while concealing axle nuts and bearings from road grime. By keeping contaminants out, they reduce exposure-related wear and the need for frequent cleanings. Chrome plating also provides a high-gloss finish that’s easy to wipe down.

• Bright chrome dome for classic baby-moon styling
• Covers axle openings to limit dirt and water ingress
• Durable plating resists rust and simplifies cleaning
