Best Peterbilt 579 Aftermarket Parts: 10 Upgrades That Pay for Themselves
Best Peterbilt 579 Aftermarket Parts: 10 Upgrades That Pay for Themselves
Running a Peterbilt 579 means keeping your rig in top shape. Whether you're an owner-operator grinding cross-country or managing a small fleet, finding reliable Peterbilt 579 parts is essential—and the right aftermarket upgrades can actually save you money in the long run. We've been in the truck parts business for years, and we've seen what works. At EverTrust Truck Parts, we stock OEM-fit parts that deliver durability, performance, and real value.
This guide covers 10 essential aftermarket upgrades for your 579. Each one addresses a common pain point: visibility, aerodynamics, durability, or appearance. More importantly, each one pays for itself through improved fuel efficiency, reduced downtime, or extended component life. Let's dig in.
1. Halogen Headlight 579/587 — The Budget-Friendly Visibility Fix
If you're running original equipment or aging headlights, a halogen upgrade is the no-brainer starting point. Our halogen headlights (OEM part numbers P54-6163-100 and P54-6163-100R) fit 579 and 587 models perfectly and deliver noticeably brighter output than worn OEM units. For an owner-operator, better visibility means fewer close calls and safer night driving—which directly impacts insurance rates and accident-free records.
Halogen lights are proven, affordable, and reliable. They're ideal if you're not ready to jump to LED but need immediate improvement. Installation takes less than an hour, and these lights last 500+ hours. Cost-benefit analysis: you'll recoup the investment through insurance savings and reduced accident risk within months. We ship halogen headlights in-stock daily, so you're back on the road fast.
Why it pays for itself: Reduced accident risk, faster inspection pass-throughs, and insurance premium reductions for owner-operators with clean records.
2. LED Headlight 579/587 — The Long-Term Play
Once you're ready to invest, LED headlights are the step up. Using OEM compatibility (P54-6163-100), our LED units deliver superior brightness, a whiter light spectrum, and dramatically longer lifespan—up to 25,000 hours. For a driver averaging 120,000 miles per year, that's roughly 7–10 years of reliable lighting. Do the math: if you replace a halogen light every 18–24 months, LED pays for itself in under 3 years.
LED lights also use less current, which means lower alternator strain and better fuel efficiency. Owner-operators report 2–3% improvement in fuel economy after switching to LED. Over a year, at 120,000 miles and 6–7 mpg, that's substantial. The brighter, more consistent light beam also reduces eye fatigue on long hauls. Browse our LED headlight options and compare the total cost of ownership—LED wins almost every time.
Why it pays for itself: Lower replacement frequency (7+ years vs. 2 years), reduced fuel consumption, and decreased alternator wear.
3. Next Gen Headlight Assembly (2022+) — For Modern 579 Owners
If you're running a 2022 or newer 579, Peterbilt introduced next-generation headlight assemblies designed from the ground up for improved aerodynamics and integrated LED technology. These aren't just brighter—they're engineered for the latest safety standards and reduce drag compared to older designs. Next-gen 579 owners often see fuel economy improvements of 3–5% with the aerodynamic headlight update.
The integrated design also means fewer loose wires, reduced maintenance headaches, and a cleaner engine bay. Installation is straightforward, and these assemblies are sealed units, so water intrusion is virtually eliminated. If you own a 2022+ 579, upgrading to OEM next-gen specs is often cheaper than chasing compatibility issues with older aftermarket parts. Explore next-gen headlight assemblies and see how they fit your model year.
Why it pays for itself: Improved fuel economy (3–5%), reduced maintenance, and future-proofing against parts obsolescence.
4. Chrome Mirror 579/587/567 — Heated & Powered Visibility
Your mirrors are your lifeline. A quality chrome mirror assembly with integrated heating and power adjustment isn't just cosmetic—it's functional. Our heated, powered chrome mirrors fit 579, 587, and 567 models and feature dual-stage heating, power extension/retraction, and durable chrome finish. Heated mirrors prevent frost and ice buildup in winter, which eliminates blind spots during early morning starts.
Owner-operators report that heated mirrors pay for themselves by preventing mirror-related accidents and fines. Power adjustment means faster setup before dispatch, reducing idle time and fuel waste. The chrome finish also looks professional—critical if you're hauling high-value freight or representing your brand. Installation requires basic wiring, and we include detailed instructions. Check out our chrome mirror assemblies and feel the difference on your next winter run.
Why it pays for itself: Prevention of mirror-related accidents, reduced idle time, and professional appearance for premium freight contracts.
5. Next Gen Chrome Mirror — Heated & Powered (2022+ Rig)
For 2022+ 579 owners, next-generation chrome mirrors are built to match modern 579 styling and integrate seamlessly with updated electrical systems. These assemblies feature the same heating and power functionality as standard models but with improved connector compatibility and reduced installation time. The next-gen design also accounts for updated aerodynamic guidelines, meaning less wind noise and better fuel efficiency on highway runs.
Next-gen mirrors use updated heating elements that draw less electrical load, reducing alternator stress compared to older designs. Power circuits are also hardened against moisture intrusion, so reliability is higher. If you're running a newer 579 and your mirrors are stock, upgrading to next-gen specs eliminates compatibility headaches down the road. View next-gen chrome mirror options and future-proof your rig.
Why it pays for itself: Lower electrical draw, improved reliability, and seamless integration with modern 579 systems and future upgrades.
6. Next Gen Black Mirror — Modern Aesthetic
Some owner-operators prefer the aggressive look of black mirrors paired with a polished chrome grille. Our next-gen black mirror assembly delivers that modern aesthetic while maintaining all the heating, power adjustment, and durability features you need. Black mirrors hide dust and road grime better than chrome, which means fewer washes and lower maintenance. The matte black finish is also easier on the eyes during dawn and dusk driving—less glare means reduced eye fatigue.
The next-gen black mirror is engineered for 2022+ 579 models, so wiring and fitment are exact. These mirrors hold up well to UV exposure and salt spray, making them ideal for coastal and winter operations. Installing a black mirror isn't just about looks—it's a practical upgrade that reduces maintenance time and improves visibility in certain lighting conditions. Browse next-gen black mirror assemblies and make your 579 stand out.
Why it pays for itself: Reduced washing and maintenance, decreased eye fatigue from reduced glare, and improved appearance for owner-operator branding.
7. Chrome Bumper — Protection & Curb Appeal
Your bumper takes a beating. Road debris, parking lot contact, and everyday wear degrade stock bumpers fast. A quality chrome bumper (OEM part number N71-6140-20100) replaces worn steel with durable chrome-plated material that absorbs impact better and looks professional. Chrome also reflects light, making your rig more visible at night—a safety bonus.
For owner-operators hauling high-value loads or competing for premium freight contracts, a polished chrome bumper signals professionalism and pride in your equipment. It also protects your frame from rust and corrosion, extending the life of your undercarriage. Installation is straightforward, and a fresh chrome bumper is one of the most cost-effective appearance upgrades available. The combination of bumper + grille + mirrors creates a cohesive, premium look. Check out our chrome bumper options and upgrade your front end.
Why it pays for itself: Reduced frame rust and corrosion, professional appearance for freight marketing, and improved nighttime visibility.
8. Complete Grille with Mesh (2013-2022) — Aerodynamic & Protective
Your grille is the gateway to your engine bay, and a quality replacement does triple duty: protects your radiator from road debris, improves aerodynamics, and enhances curb appeal. Our complete grille with mesh insert (OEM part number L29-6157-100) fits 579 models from 2013–2022 and includes the bug screen. The mesh design balances airflow with protection—critical for efficient cooling in hot climates and heavy pulling.
A damaged or missing grille forces bugs, rocks, and debris into your radiator, reducing cooling efficiency and increasing engine temperature. Overheating costs you downtime, fuel, and potentially engine damage. Our mesh grille prevents this while also looking sharp. The complete assembly ships ready to install, and the integrated bug screen means one less part to source. If you're running an older mesh design or a damaged grille, this upgrade is overdue. View our 2013-2022 grille options and protect your investment.
Why it pays for itself: Reduced radiator damage and overheating, improved engine cooling efficiency, and prevention of costly downtime.
9. Complete Grille (2023+) — Next-Gen Aerodynamics
Peterbilt's 2023+ 579 received a refreshed grille design (OEM part number PE-034) engineered for improved aerodynamics and integrated cooling airflow. This next-gen grille is slightly wider and features optimized mesh spacing for better radiator cooling at highway speeds. For owner-operators running 2023+ models, switching to OEM next-gen specs ensures perfect fitment and factory airflow dynamics.
The updated grille also accounts for Peterbilt's latest DEF and cooling system configurations, so compatibility is guaranteed. Installation is straightforward, and the grille bolts directly to your existing mounting points. If your 2023+ grille is damaged or worn, staying with next-gen specs ensures you maintain factory cooling performance. Explore 2023+ grille assemblies and keep your rig performing at factory specs.
Why it pays for itself: Optimized engine cooling, maintained fuel economy, and prevention of cooling-related downtime and engine wear.
10. Hood Logo — Brand Recognition & Pride
Don't overlook the hood logo. A polished, well-maintained Peterbilt hood logo is one of the first things shippers see, and it signals professional pride in your equipment. Over time, logos fade, corrode, or go missing—hurting your brand presence. A replacement hood logo is affordable and easy to install, and it's one of the quickest ways to refresh your rig's appearance.
For owner-operators with custom paint jobs or fleet operators managing brand consistency, a clean hood logo is non-negotiable. It's also a simple warranty-friendly upgrade that doesn't require electrical work or special tools. Pair a fresh logo with a detailed grille, polished mirrors, and a chrome bumper, and your 579 looks like a million bucks. The investment is minimal, but the perception is premium.
Why it pays for itself: Enhanced brand perception, improved freight marketing appeal, and simple preventive maintenance against logo fade and corrosion.
Bonus Parts Worth Considering
Beyond the core 10, a few parts deserve honorable mentions. If you're building a comprehensive front-end upgrade, consider our grille without bug screen if you prefer custom mesh, and for next-gen owners, the next-gen black mirror cover is a slick add-on for that modern look. Don't overlook the coolant reservoir either—replacement reservoirs prevent freeze-up and overheating in extreme climates and are cheaper than engine repair.

FAQ: Peterbilt 579 Parts & Upgrades
What's the difference between halogen and LED headlights for a 579?
Halogen lights are affordable and proven, with a 500-hour lifespan and lower upfront cost. LED lights are brighter, last 25,000+ hours, and reduce fuel consumption by 2–3% due to lower electrical draw. For most owner-operators, LED pays for itself in under 3 years through fuel savings and reduced replacement frequency.
Do I need heated mirrors in warm climates?
Heated mirrors deliver benefits beyond winter deicing. They help prevent dust and dirt buildup in cold nights, reduce condensation, and provide redundant visibility in unexpected frost. Even in warm climates, the power adjustment feature alone justifies the upgrade—faster mirror setup means less idle time and wasted fuel.
Will aftermarket 579 parts affect my warranty?
Most aftermarket parts don't void your Peterbilt warranty as long as they're OEM-compatible and installed correctly. Always check your warranty documentation, and when in doubt, contact your dealer. EverTrust parts are OEM-fit and backed by compatibility guarantees, so you're protected.
How do I know which grille and mirror styles are compatible with my model year?
Always verify your 579 model year—Peterbilt made significant updates in 2013, 2022, and 2023. Our product pages list compatible years clearly, and our team is available to confirm fitment before purchase. When you order, include your VIN or model year to ensure the right part ships.
