Peterbilt 379 Exterior Parts

Frequently Asked Questions About Peterbilt 379 Exterior Parts

Will these exterior parts fit my specific year Peterbilt 379?

Most of our Peterbilt 379 exterior parts are designed to fit models from 1987 to 2007. However, there are some variations between model years, particularly with bumpers and grilles manufactured before and after 1995. Always check the product description for specific year compatibility, or contact our support team with your OEM number to ensure proper fitment. Extended hood models may require different parts than standard hood configurations.

What's the difference between chrome, stainless steel, and aluminum exterior parts?

Chrome-plated steel parts offer the brightest mirror finish but require regular polishing to prevent rust and pitting. Stainless steel parts are more durable and resistant to corrosion, maintaining their appearance with less maintenance, though they have a slightly different shine than chrome. Aluminum parts are the lightest weight option and won't rust, but they're softer and more prone to denting. For bumpers specifically, 16-gauge stainless steel provides the best balance of durability and appearance for most drivers.

Can I install these exterior parts myself, or do I need professional help?

Many exterior parts like bug shields, sun visors, and mirror covers can be installed with basic hand tools in 30-60 minutes. Bumpers and grilles typically require 2-4 hours and may need two people for safe handling. Most parts come with mounting hardware and basic instructions, but you'll need standard wrenches, sockets, and possibly a drill for some accessories. Complex items like full aero packages or custom light bars may require professional installation to ensure proper alignment and compliance with regulations.

How do I match aftermarket parts to my truck's existing chrome and finish?

Triple chrome plating is the industry standard that matches OEM Peterbilt chrome best. When mixing parts from different manufacturers, slight variations in shade may occur, especially between older and newer chrome. For the most consistent appearance, replace matching sets (like both bumper ends or all exterior handles) at the same time. Stainless steel parts will have a different appearance than chrome and are best used as complete sets rather than mixed with chrome pieces.

Are aftermarket exterior parts as durable as OEM Peterbilt parts?

Quality varies significantly between manufacturers. Premium aftermarket brands often match or exceed OEM specifications, using 16-18 gauge steel for bumpers and 304-grade stainless where applicable. Look for parts with warranty coverage of at least one year. Cheaper imports may use thinner materials or lower-quality chrome that can peel or rust within months. Check product reviews and thickness specifications - OEM-quality bumpers typically weigh 40-60 pounds, while inferior versions may weigh significantly less.
