Frequently Asked Questions About Peterbilt 359 Hoods & Related

What years and models are compatible with Peterbilt 359 hoods?

Peterbilt 359 hoods are designed specifically for 359 models manufactured from 1967 to 1987. While the mounting points remained consistent throughout production, there are slight variations between early models (1967-1979) and later models (1980-1987), particularly in grille mounting brackets and headlight configurations. Some hoods may also fit Peterbilt 379 models with minor modifications, but we recommend verifying your specific OEM and model year before ordering to ensure proper fitment.

What materials are available for replacement hoods, and which is best for my needs?

We offer hoods in three primary materials: fiberglass, aluminum, and steel. Fiberglass hoods are the most popular choice, weighing 40-60% less than steel while providing excellent durability and paint adhesion. Aluminum hoods offer superior corrosion resistance and moderate weight savings, ideal for coastal or high-moisture environments. Steel hoods provide maximum durability for heavy-duty applications but add significant weight. Most customers choose fiberglass for the best balance of weight savings, cost, and longevity.

Do I need special tools or professional installation for hood replacement?

Hood replacement typically requires basic hand tools including socket sets, wrenches, and a helper for safe handling. The process involves disconnecting the hood hinges, support cables, and any electrical connections for hood-mounted lights. While experienced mechanics can complete installation in 2-3 hours, we recommend professional installation if you're unfamiliar with heavy truck components. Critical alignment of the hood to fenders and grille requires patience and may need adjustment shims for proper gaps.

What hood styles and designs are available for the Peterbilt 359?

We stock several hood styles including the classic louvered design, smooth hoods without louvers, and custom options with various vent configurations. Popular modifications include cowl induction scoops, raised center sections, and custom air intake cutouts. Standard heights range from stock to 4-inch extended versions for trucks with larger engines or modified air cleaners. Most hoods come in primer finish, ready for your custom paint application.

How do I handle common fitment issues with aftermarket hoods?

Aftermarket hoods may require minor adjustments for perfect fitment. Common issues include slight gaps at the fender junction, which can be corrected with adjustment shims, and hinge alignment that may need repositioning. Hood-to-grille spacing often requires fine-tuning the rubber bumpers and latch mechanism. Always test-fit the hood before final painting to address any alignment issues.
