Frequently Asked Questions About Freightliner SD 108-122 Hood Replacement Parts

What years and models are compatible with these SD 108-122 hood parts?

These hood replacement parts are designed specifically for Freightliner SD models with 108-inch to 122-inch BBCs (Bumper to Back of Cab measurements). They typically fit model years 2002-2017, including the SD, Coronado SD, and 122SD variants. However, we strongly recommend verifying your exact BBC measurement and VIN before ordering, as slight variations can exist between specific model years. If you're unsure about compatibility, contact our support team with your truck's VIN for precise fitment confirmation.

Are these hoods made from fiberglass or aluminum, and which is better for my needs?

We offer both fiberglass and aluminum hood options. Fiberglass hoods are lighter weight (typically 80-120 lbs) and more affordable, making them ideal for owner-operators focused on fuel efficiency and initial cost savings. Aluminum hoods are heavier (150-200 lbs) but offer superior durability and resistance to cracking, making them better for severe-duty applications or fleets prioritizing longevity. Both materials meet OEM specifications and include proper reinforcement at mounting points.

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

Hood replacement typically requires basic shop tools including socket sets, torque wrenches, and ideally a hoist or overhead crane for safe handling. The process involves disconnecting hood cables, removing hinge bolts, and proper alignment during reinstallation. While experienced mechanics can complete installation in 3-4 hours, we recommend professional installation if you lack overhead lifting equipment or experience with heavy truck components. Most hoods come pre-drilled, but minor adjustments to mounting holes may be necessary for perfect alignment.

What finish options are available, and do hoods come primered or painted?

Most replacement hoods arrive in primer finish, ready for painting to match your truck. We offer gel-coated fiberglass options that provide a smooth, paint-ready surface requiring minimal prep work. Some aluminum hoods feature mill finish or can be ordered with primer. For exact color matching, we recommend professional painting using your truck's paint code. Budget an additional $800-1500 for professional paint and prep work if you need a finished appearance.

Will aftermarket hoods affect my warranty or resale value?

Quality aftermarket hoods that meet OEM specifications typically don't void existing warranties, as they're considered replacement parts rather than modifications. Our hoods maintain original mounting points and dimensions, ensuring proper fit with existing components like grilles, headlights, and air intakes. For resale value, a properly installed and painted replacement hood often improves truck appearance and value compared to damaged original parts. Always keep installation receipts and documentation to show proper maintenance history to future buyers.
