Will these parts fit my specific Peterbilt 389 model year?

Most parts listed are designed for the Peterbilt 389, but cab configurations can vary by year, sleeper type, and factory options. We recommend checking the fitment notes on each product page and comparing part numbers or measurements to your truck before ordering. If you are unsure, contacting our team with your VIN or truck specs can help confirm compatibility.

What materials and finishes are available for cab parts?

Depending on the part, you will find options in steel, aluminum, and fiberglass, with finishes ranging from raw or primed surfaces to painted or chrome-plated options. Raw and primed parts typically require paint matching to your truck, while pre-finished parts are ready to install. Each product listing specifies the material and finish so you know what to expect before purchasing.

Do these cab components require professional installation?

Installation complexity depends on the specific part. Trim pieces and smaller accessories are often straightforward for an experienced DIYer with common tools, while structural components like cab mounts or panels affecting the cab's integrity are best installed by a qualified technician. If a part involves welding, cutting, or affects cab alignment, professional installation is strongly recommended.

Are these parts OEM or aftermarket, and does that affect quality?

This category includes both OEM and aftermarket options, and each is clearly labeled on the product page. OEM parts are built to original Peterbilt specifications, while aftermarket parts can offer a more budget-friendly alternative and, in some cases, additional style or material choices. Quality can vary between aftermarket manufacturers, so we work with trusted suppliers to ensure the parts we carry meet durability and fitment standards for daily use.
