Peterbilt 567/579 Sleeper Rear Acc.

Frequently Asked Questions About Peterbilt 567/579 Sleeper Rear Acc.

What kind of parts are included in this category?

This category covers exterior accessories that mount to the rear of the sleeper cab on Peterbilt 567 and 579 models, such as rear panels, trim pieces, storage and battery box covers, and other sleeper-back components. These parts are designed to fit the specific body lines and mounting points on the rear of the 567/579 sleeper.

Will these parts fit both the 567 and 579, or are they model-specific?

Many sleeper rear accessories share a common mounting pattern across the 567 and 579, but panel shapes and cutouts can differ depending on sleeper size, cab configuration, and model year. Always check the listed fitment details on each product page and compare against your truck's VIN or existing panel before ordering to confirm an exact match.

What materials and finishes are available?

Most rear sleeper accessories are offered in aluminum or steel, with finish options that may include raw, painted, or diamond plate depending on the specific part. Aluminum and diamond plate options are popular for reduced weight and added durability, while painted or raw finishes allow for a closer match to factory color or custom paint work.

What is involved in installing these accessories?

Installation typically involves removing the factory panel or cover and bolting on the replacement piece using the existing mounting holes and hardware. Some parts may require minor drilling or the use of new fasteners if the factory hardware is worn or missing. We recommend reviewing the product description for any included hardware or specific installation notes, and having basic hand tools on hand before starting the job.

Do these accessories affect factory clearances, lighting, or wiring?

Since these parts mount to the rear of the sleeper, it is important to check for any lights, wiring harnesses, or vents in the area before installation. Most replacement panels and covers are designed to maintain factory clearances and accommodate existing wiring or light mounts, but you should confirm this on the product page or by contacting our team if your truck has aftermarket lighting or modified wiring in that area.
