Peterbilt 579 Upgrades: Best Chrome and LED Parts (Complete Guide)
Upgrading the Peterbilt 579
The Peterbilt 579 is Peterbilt's aerodynamic flagship — a modern, fuel-efficient truck that still looks aggressive with the right upgrades. While it doesn't have the same chrome real estate as the classic 389, the 579 has plenty of upgrade potential in lighting, grille work, and interior accessories.
Top Upgrades for the 579
1. LED Headlights
The single most impactful upgrade on a 579. Factory halogen headlights on pre-2019 models are noticeably dim compared to modern LED projectors. A good LED headlight upgrade gives you 3–5x more light output with a pure white 6000K beam pattern.
The 579 uses a unique headlight shape that changed between the original (2013–2018) and updated (2019+) models. Make sure to select the correct generation when ordering.
2. Chrome Grille and Grille Surround
The 579's grille opening is smaller than the 389's, but a chrome grille insert or surround still makes a significant visual difference. Chrome grille trim pieces frame the front end and add definition to the 579's aerodynamic profile.
Options include full chrome grille replacements, chrome bar inserts, and chrome surround trim that frames the factory grille.
3. LED Cab Lights
Five amber LED cab lights across the roof are a must-have for any 579 build. The 579 uses a specific cab light mounting pattern — choose OEM-fit LED replacements for a plug-and-play installation. Clear lens with amber LED is the most popular option for the 579's modern styling.
4. Chrome Mirror Covers
The 579's large aerodynamic mirrors are highly visible from the side. Chrome mirror covers snap over the factory housing and instantly brighten the side profile. Most are ABS plastic with triple-chrome plating for durability.
5. Chrome Door and Cab Trim
Chrome door handle covers, window trim, and cab panel accents add subtle chrome detail without going full show truck. These small pieces install in minutes with adhesive or snap-on clips.
6. Interior: Steering Wheel and Shift Knob
A chrome steering wheel transforms the 579's interior. The 579 uses the same steering column as most modern Peterbilts, so aftermarket steering wheel options are plentiful. Pair it with a chrome shift knob for a complete interior refresh.
7. Spike Lug Nut Covers
Chrome spike lug nut covers are the finishing touch on any 579. Standard 33mm size fits all wheel positions. Add matching axle covers for a complete wheel chrome package.
