Peterbilt 379 Short Hood vs. Extended Hood

Peterbilt 379 Short Hood

The Peterbilt 379 short hood is the more compact version of this iconic rig, measuring 119” BBC (bumper-to-back-of-cab). This design makes it ideal for drivers who navigate tight spaces, city streets, and crowded yards.

Why Choose a Short Hood?

• Better Maneuverability – A shorter front end means an improved turning radius, perfect for urban routes and tricky dock setups.
• Lighter Weight – Less hood = less weight = slightly better fuel efficiency and less strain on the front axle.
• Easier Maintenance – Accessing the engine, grill, and headlights is more convenient compared to a long-nose model.

However, some drivers feel the shorter hood loses the classic Peterbilt look that many owner-operators love. 

If you prefer a longer, more aggressive profile, the extended hood might be your style.

• Advantages: tighter turning radius, easier maneuverability, and reduced weight.
• Best for city driving, tighter docking areas, and fleets needing agility.

Peterbilt 379 Extended Hood

Defining the 379 Extended Hood and Its Signature Look

The Peterbilt 379 extended hood measures 127” BBC, giving it that long-nose, classic American trucker aesthetic. 

It's the go-to choice for owner-operators who value style, stability, and better airflow to the engine.

Why Choose an Extended Hood?

Timeless Look – The 379 extended hood is legendary on the road, turning heads at truck stops and giving your Pete a commanding presence.

Better Engine Cooling – A longer hood provides more space between the grille and radiator, allowing for better airflow and heat dissipation—a huge plus for heavy-haul and long-haul drivers.

More Stable Ride – The extended wheelbase offers better road stability, especially at high speeds and in open highway conditions.

The downside?

Parking and maneuvering take more skill, especially in tight yards or city environments. But for many drivers, the road presence and performance benefits outweigh the drawbacks.

Long-haul drivers who prefer more cabin space, engine access, and comfort can opt for an extended hood.

Key Features of the Peterbilt 379 Hood

• Grill and grille surround: Impact on air intake and cooling.
• Headlights and top panel: How different configurations affect visibility.
• Passenger side & cab support: Ensuring proper alignment and fit.
• Bumper-to-back-of-cab (BBC) measurement: How it determines hood compatibility.

How to Choose the Right Hood Design for Your Pete 379

Factors to Consider:

Road Conditions – If you run mostly city routes with tight turns, a short hood makes life easier. If you do long-haul work, an extended hood may be the better choice.

Personal Preference – Do you prefer the classic long-nose Peterbilt stance, or is function more important than looks?

Aerodynamics & Fuel Economy – While the difference is slight, shorter hoods tend to be more fuel-efficient due to reduced wind resistance.

Cost Comparison Breakdown: New vs Used vs Aftermarket

Your budget plays a big role in choosing a Peterbilt 379 hood replacement.

New OEM Hoods – The most expensive but offers perfect fit and longevity.

Used Hoods – More affordable, but check for wear, cracks, and damage before buying.

Aftermarket Hoods – A solid middle-ground option, offering quality at a lower price than OEM. Some brands are nearly as good as original factory parts.

Where to Shop for Peterbilt Truck Parts

Online Truck Parts Stores – Many websites specialize in new and aftermarket hoods, with shipping options nationwide.

Salvage Yards – A great way to find used hoods at a lower price—just inspect carefully for cracks, dents, or hidden damage.

Local Truck Shops & Dealerships – If you need a hood fast and want expert guidance, a truck parts shop near you is a solid choice.

Maintaining and Replacing Your Peterbilt Hood

Tools Needed for Minor Repairs and Panel Replacements

• Socket set – Essential for removing and securing hood bolts.
• Rubber mallet – Helps fix small dents without damaging the hood’s surface.
• Fiberglass repair kit – Useful for patching minor cracks and reinforcing weak spots.
• Body filler and sandpaper – Smooths out surface imperfections before painting.
• Hood alignment tools – Ensures proper fitting and prevents uneven wear.

Signs Your Hood Needs Replacing

• Cracks spreading across panels can weaken the hood’s structure.
• Dents that won’t pop out may affect aerodynamics and resale value.
• Misalignment issues cause uneven gaps between the hood and cab.
• Excessive wear on hinges and mounts can lead to instability while driving.

How Hood Damage Affects Truck Performance

• A cracked center panel reduces structural integrity and increases vibration.
• Damaged hood edges allow moisture and debris inside, leading to rust.
• Loose or misaligned panels can affect aerodynamics and fuel efficiency.
• A worn-out hood surround may cause the grille to shift, impacting airflow.
