Frequently Asked Questions About Peterbilt Hoods & Related

What years and models will these hoods fit, and how do I know if it's compatible with my truck?

Most aftermarket Peterbilt hoods are designed to fit specific model ranges. Generally, hoods for 379 models fit years 1987-2007, while 389 hoods fit 2008 and newer. However, compatibility can vary based on your truck's configuration. Check your OEM plate for the exact model designation and compare it with the product specifications. Pay special attention to whether you have an extended hood, standard hood, or short hood configuration, as this affects fitment. When in doubt, measure your existing hood length from the back edge to the front edge and compare with the listed dimensions.

What's the difference between fiberglass and aluminum hoods, and which one should I choose?

Fiberglass hoods are typically 40-60% lighter than steel, improving fuel economy and being easier to lift. They're also more affordable and won't rust. However, they can crack on impact and may require more frequent hardware adjustments. Aluminum hoods offer superior durability and maintain their shape better over time, but cost significantly more. For drivers logging heavy miles or operating in harsh conditions, aluminum is worth the investment. Weekend warriors and show truck owners often prefer fiberglass for the weight savings and lower cost.

Can I install a new hood myself, or do I need professional help?

Hood installation is manageable for those with basic mechanical skills, but requires at least two people due to size and weight. You'll need basic hand tools, proper jack stands or supports, and about 3-4 hours. The main challenges include aligning the hood hinges properly, adjusting the hood stops and latches, and ensuring proper gaps around the fenders and cowl. Many customers report that while the physical installation is straightforward, achieving perfect alignment can be time-consuming. If you're not comfortable with adjustments or lack a helper, professional installation typically runs $200-400.

Do aftermarket hoods come painted, and will the color match my truck?

Most aftermarket hoods come in primer only and require painting. While some suppliers offer pre-painted options, exact color matching to weathered factory paint is challenging. For best results, have your hood painted by a professional using your truck's paint code, found on the driver's door jamb. Budget $400-800 for professional prep and paint. If ordering a pre-painted hood, be aware that factory paint codes can result in slight variations from your existing finish due to sun fade and age.

What additional parts might I need when replacing my hood?

Beyond the hood itself, you may need new hood hinges if yours are worn (common on trucks over 10 years old), rubber hood bumpers, latch assemblies, and grille mounting brackets. Fiberglass hoods often require reinforcement plates at stress points. Budget an extra $150-300 for these components. Also check your hood mirrors, as some aftermarket hoods have different mirror mounting hole patterns. Don't forget weatherstripping - old seals rarely transfer well to new hoods and replacement costs about $50-75.
