LisylineAuto Peterbilt 378/379 Hood Hinge Pivot Bushing Kit — Iron & Plastic, Complete Set for Short & Extended Hoods

LisylineAuto's engine hood hinge pivot bolt bushing kit replaces worn rubber parts on Peterbilt 378 and 379 hoods with a durable iron-and-plastic assembly designed for long service life.

If your Peterbilt 378 or 379 hood wobbles, squeaks, or has excessive play at the pivot, these replacement hinge bushings and bolt components restore a tight, reliable connection. The kit is manufactured from high-strength iron and engineered plastic—materials chosen to resist crushing and wear that often plague original soft rubber bushings. It’s supplied as a complete set to swap out the worn pieces and is compatible with both short and extended hood configurations.

Will this kit fit my Peterbilt 378 or 379 hood?

Yes — the kit is specifically made to replace the original factory bushings identified by OEM numbers 23-15273, 13-04726, and 13-04727. It works with both short-hood and extended-hood models for the Peterbilt 378 and 379 series, so you won’t need model-specific variations.

• Direct OEM compatibility: replaces 23-15273, 13-04726, 13-04727
• Fits Peterbilt 378 and 379 short and extended hoods
• Sold as a complete set for a single hinge assembly

How does the iron-and-plastic design improve performance?

The combination of iron for structural strength and engineered plastic for a low-friction interface offers a more durable alternative to factory rubber bushings. Iron resists bending and deforming under load, while the plastic sleeves reduce noise and wear at the pivot point, extending service intervals.

• Iron components provide rigidity and load resistance
• Plastic sleeves lower friction and dampen vibration
• Less deformation compared with rubber results in tighter hood alignment

What’s included and how difficult is installation?

The package contains one complete set of hinge bushings and pivot hardware required to replace the worn parts; it does not include installation instructions. Installation is straightforward for anyone with basic mechanical tools and experience removing hood pivot bolts, but professional installation is recommended if you are unfamiliar with heavy-truck hinges.

• Contains one set of hinge bushings and pivot bolt components
• No printed instructions included; basic mechanical skill required
• Typical installation uses common sockets, punches, and torque tools

Will replacing these bushings reduce hood noise and play?

Replacing degraded rubber bushings with this kit noticeably reduces lateral play, stops squeaks, and improves hood alignment. The firmer pivot components help maintain consistent hood gap and reduce the need for frequent readjustments during routine service.

• Reduces hood side-to-side movement and vibration
• Minimizes squeaks and rattles at the hinge point
• Helps preserve correct hood gap and alignment over time

Who is this for: This LisylineAuto hinge bushing kit is intended for fleet owners, owner-operators, and maintenance shops servicing Peterbilt 378 and 379 trucks that need a reliable replacement for aging rubber pivot bushings. It’s ideal when you want a sturdier, longer-lasting pivot solution that keeps the hood secure and reduces maintenance downtime. If you operate heavy miles, haul long routes, or simply prefer more durable components over OEM rubber items, this kit offers a direct-fit alternative backed by robust materials and clear OEM cross-reference numbers.
