Peterbilt 375/377 Sleeper Rear Acc.

Frequently Asked Questions About Peterbilt 375/377 Sleeper Rear Acc.

What kinds of parts are included in this category?

This category covers accessories that mount to the rear of the sleeper cab on Peterbilt 375 and 377 models, such as rear sleeper panels, battery box covers, fuel tank fairings, storage compartments, and back-of-cab trim pieces. These components are designed to fit the specific body lines and mounting points found on the 375/377 sleeper cab.

Will these accessories fit my specific Peterbilt 375 or 377 configuration?

Most items in this category are built to match the factory mounting points and body contours of the 375/377 sleeper cab, but exact fitment can vary depending on cab length, sleeper style, and production year. Before ordering, check the listed specifications and measurements against your truck, or contact our parts team to confirm compatibility with your exact configuration.

What materials and finishes are available?

Sleeper rear accessories are commonly offered in aluminum or steel, often with a diamond plate texture for added durability and a distinctive look. Finish options typically include raw/unpolished aluminum, polished aluminum, and painted or powder-coated steel. Choosing the right material depends on whether you prioritize weight savings, corrosion resistance, or a specific appearance to match the rest of your truck.

Do these parts come with mounting hardware, and how difficult is installation?

Hardware inclusion varies by product, so check the individual listing to confirm whether brackets, bolts, or fasteners are included. Installation generally involves bolting the accessory to existing mounting points on the sleeper, and most parts are designed for standard hand tools. However, some panels or fairings may require drilling or fabrication to align properly, especially if your truck has aftermarket modifications.

How do I clean and maintain these accessories to keep them looking good?

Aluminum and diamond plate pieces should be washed regularly with mild soap and water to prevent road grime and salt buildup, which can lead to pitting or corrosion over time. Polished aluminum will need periodic re-polishing to maintain its shine, while painted or powder-coated steel pieces should be inspected for chips or scratches that could expose bare metal to moisture.
