Peterbilt 567/579 Hub Adapters

Frequently Asked Questions About Peterbilt 567/579 Hub Adapters

What do these hub adapters actually do?

Hub adapters allow you to mount aftermarket hub caps, covers, or other axle-end accessories onto your Peterbilt 567 or 579 by matching up to the factory hub bolt pattern and stud spacing. They act as the bridge between your truck's hub and the decorative or functional cap you want to install, without altering the hub itself.

How do I know these adapters will fit my truck?

Fitment depends on your specific axle configuration, front or rear position, and hub bolt pattern, which can vary between Peterbilt 567 and 579 models and production years. Always check the listed specs against your truck's hub measurements or VIN-specific axle data before ordering, and reach out to our team if you are unsure so we can help confirm the correct part.

What materials are these adapters made from, and will they hold up long-term?

Most hub adapters in this category are built from stainless steel or heavy-gauge steel with a durable finish designed to handle road exposure, vibration, and temperature swings. The finish options typically include polished or chrome-style looks, but the underlying material is what matters most for long-term durability under constant highway use.

Can I install these myself, or do I need a shop to do it?

Installation is generally straightforward for anyone comfortable doing basic wheel-end work, since it usually involves securing the adapter over the existing studs before the hub cap or cover goes on. That said, if you are not familiar with proper torque specs or wheel-end safety procedures, we recommend having a qualified technician handle the install to make sure everything is seated and tightened correctly.

Will adding a hub adapter affect my wheel-end warranty or safety inspection?

Hub adapters are designed as add-on accessories and should not interfere with the structural integrity of your wheel end when installed correctly, but modifications to wheel components can sometimes raise questions during inspections or with certain warranty providers. If you have an active hub or bearing warranty, it is worth checking with your dealer or manufacturer beforehand, and always confirm the adapter does not obstruct access to lug nuts, valve stems, or other components required for routine inspections.
