Frequently Asked Questions About Peterbilt 567/579 Parts

What years and models are compatible with your Peterbilt 567/579 bumpers?

Our bumpers are designed to fit Peterbilt 567 models from 2013 to present and Peterbilt 579 models from 2012 to present. However, compatibility can vary based on your truck's specific configuration, including whether you have a set-forward or set-back axle, day cab or sleeper, and any factory-installed options. We recommend checking your OEM or calling our team at 1-888-875-2358 with your truck's details to ensure proper fitment before ordering.

Are your bumpers made from chrome-plated steel or stainless steel, and which is better?

We offer both chrome-plated steel and polished stainless steel options. Chrome-plated steel bumpers provide a mirror-like finish at a lower cost but require regular maintenance to prevent rust and pitting. Stainless steel bumpers are more expensive upfront but offer superior corrosion resistance and maintain their appearance longer with minimal maintenance. For trucks operating in harsh winter conditions with road salt exposure, we typically recommend stainless steel for its durability.

What tools and hardware are needed for installation, and how long does it take?

Installation typically requires basic hand tools including socket wrenches, torque wrench, and potentially a drill for auxiliary light mounting. Most bumpers come with mounting brackets and grade 8 bolts, but you may need to reuse some factory hardware. Professional installation usually takes 2-4 hours depending on whether you're adding lights or other accessories. Many customers with mechanical experience successfully complete DIY installation in 3-5 hours following the included instructions.

Do your bumpers accommodate factory fog lights and sensors?

Most of our replacement bumpers include provisions for factory fog lights and can accommodate parking sensors, though some aftermarket bumpers may require modification. Bumpers designed for 2016 and newer models typically have pre-cut openings for adaptive cruise control radar sensors. If your truck has these features, please specify when ordering or contact us to confirm compatibility with your specific setup.

What's the weight difference between aftermarket and OEM bumpers, and will it affect my truck?

Aftermarket steel bumpers typically add 50-150 pounds compared to factory bumpers, depending on the style and features. Heavy-duty bumpers with integrated tow hooks or winch mounts can add up to 200 pounds. This additional weight is generally not significant enough to affect handling or require suspension adjustments, but it may slightly impact fuel economy. The added weight actually provides better protection in minor collisions and improved appearance retention over lightweight alternatives.
