LOSTAR 4PCS 8" Dome-style chrome hub cap covers are durable metal rear wheel caps designed to fit 8-1/2" axle hubs, giving semi trucks a polished, finished look while protecting studs and bearings.

These 8" I.D. dome hub caps from LOSTAR are a purpose-built replacement set for heavy-duty trucks that use 8" wheel cap assemblies. Constructed with a chrome finish and engineered to match common axle hub dimensions, the set includes four metal caps to cover rear wheel hubs and enhance corrosion resistance and curb appeal. Each cap measures about 3-1/2" tall with a 1" sidewall and fits hubs with eight 5/8" inner studs—verify your truck's hub diameter before purchase to ensure compatibility.

How do these hub caps fit my truck?

These hub cap covers are designed for hub assemblies that accept an 8" inner cap, commonly used on many Kenworth, Peterbilt, and Freightliner models. Fit depends on the axle hub's internal diameter and the number and size of inner studs, so confirm measurements on your vehicle. Installation is straightforward for anyone familiar with wheel-end work, and each cap sits over the hub to protect fasteners and bearings.

• Fits hubs with an 8" inside diameter and approximately 3-1/2" height
• Compatible with hubs having eight 5/8" diameter inner studs
• Commonly used on Kenworth, Peterbilt, Freightliner models—verify your hub first
• Includes four caps, covering both sides of a single axle or two axles

What materials and finish are used, and how long will they last?

The caps are made from metal with a chrome finish chosen to resist rust and retain a bright appearance under typical commercial use. Built to withstand road vibration and exposure to the elements, they're quality-controlled to provide long service life when installed correctly. While chrome resists corrosion, routine cleaning and inspection will help maintain their look and prevent long-term wear.

• Durable metal construction with chrome plating for corrosion resistance
• Manufactured and tested under strict quality control
• Professional-grade finish intended for heavy-duty fleet conditions
• Backed by a 1-year unlimited-mileage quality guarantee from LOSTAR

How easy is installation and what tools are required?

Installing the dome-style hub caps is typically quick: remove the old cap or protective plug, align the new cap with the hub studs, and press or tap it into place until seated. No specialized tools are required for many applications, though a rubber mallet and torque tools for removing the existing cap or lock ring can help. If you're unsure, a shop that services wheel ends can fit them in minutes.

• Simple press-fit or gently tapped into position over the hub assembly
• Common tools: rubber mallet, basic hand tools for hub access
• Can be installed roadside or in a shop by experienced technicians
• Four caps included, ready to swap in as a set
