Peterbilt 379 Truck Hoods

Choose Your Style: 379 Short Hood vs. Peterbilt 379 Extended Hood

Finding the right fitment depends entirely on your truck’s Bumper to Back of Cab (BBC) dimension. Whether you need a short hood or long hood, we stock both traditional OEM replacement styles and custom conversion kits to match your specific performance and aesthetic goals.

Peterbilt 379 Short Hood (119-Inch BBC)

The 379 short hood configuration offers tighter turning radiuses and slightly better visibility. Perfect for vocational applications or regional hauling, our short hood replacements and conversion kits bolt up cleanly to factory mounting points. Choose premium designs from Jones Performance or value-friendly, durable alternatives by TPHD and BESTfit.

Peterbilt 379 Extended Hood (127-Inch BBC)

For the ultimate classic look, our Peterbilt 379 extended hood options deliver that iconic, long-nose highway profile. These assemblies provide maximum engine bay clearance and are built to withstand the rigors of long-haul heavy-duty trucking. Find premium aluminum hood options in complete kits that feature polished stainless steel grille and surround. Or choose fiberglass and steel hood kit assemblies with bolt-on Peterbilt 379 front fenders included. For a value purchase, buy a marine-grade replacement hood shell. Most of our in-stock 127-BBC long-hoods are direct replacements for OE factory hoods.

It can also help protect your front-end structure, reduce hood rattle, improve fitment, and support long-term ownership costs. Here are the benefits: - Optimize Cooling & Airflow: Choose quality-made hoods to assist your radiator and charge air cooler (CAC) in demanding environments. - Restore Structural Integrity: Eliminate hood rattle and misalignment by replacing worn components with fresh fiberglass panels and new Peterbilt 379 hood hinges, springs, and latches.

Frequently Asked Questions About Peterbilt 379 Truck Hoods

Will this hood fit my Peterbilt 379 without modification?

Peterbilt 379 hoods are designed to match the factory body lines and mounting points for this model, but fitment can vary depending on the year of your truck and whether previous body modifications have been made. It's important to confirm the hood style matches your truck's existing hinge and latch setup before ordering, and to check with our team if you're unsure about specific year compatibility.

What materials are these replacement hoods made from, and how do they compare to the original?

Replacement hoods for the Peterbilt 379 are typically constructed from fiberglass, which is the same general material used on the factory hood. Quality can vary between manufacturers in terms of thickness, gel coat finish, and overall rigidity, so it's worth reviewing the specific product description for details on construction before making a purchase.

Do these hoods come primed or painted, or will I need to finish them myself?

Most replacement hoods are sold in a gelcoat or primed finish rather than painted to match your truck. This allows you to have the hood painted to your specific color and finish preferences after purchase. Be sure to check the individual product listing to confirm exactly what condition the hood ships in.

Can I reuse my existing hood hardware, hinges, and latches?

In many cases, hoods are designed to work with the factory hinge and latch hardware from your Peterbilt 379, allowing you to transfer that hardware over during installation. However, hardware wear or damage on your existing hood may affect fit, so it's a good idea to inspect your current hinges and latches before installation and replace any worn components as needed.

Is installing a replacement hood something I can do myself, or should I have a professional do it?

Installing a fiberglass hood is a significant job that involves aligning body panels, transferring hardware, and often reinstalling lighting and grille components. While some experienced DIYers take this on, many customers choose to have the installation done by a professional shop to ensure proper fit, alignment, and finish, especially if bodywork or painting is also required.
