Frequently Asked Questions About Peterbilt Bumpers
What Peterbilt models and years are these bumpers compatible with?
Our Peterbilt bumpers are designed for specific model years and series. Most aftermarket bumpers fit 379, 389, 388, 386, and 367 models. For 379 models, bumpers typically fit 1987-2007 year ranges, while 389 bumpers generally fit 2008 and newer. Always check the product description for exact fitment details, as mounting holes and brackets can vary between model years. If you're unsure about compatibility, contact us with your VIN number for verification.
What's the difference between chrome, stainless steel, and aluminum bumpers?
Chrome-plated steel bumpers offer a mirror finish and are typically the most affordable option, but require regular polishing to prevent rust and pitting. Stainless steel bumpers resist corrosion better and maintain their appearance longer with less maintenance, though they cost more upfront. Aluminum bumpers are the lightest option, saving 40-60 pounds compared to steel, and won't rust, but they're less impact-resistant and typically the most expensive. Consider your climate, maintenance preferences, and weight concerns when choosing.
Can I install a Peterbilt bumper myself, or do I need professional help?
Most Peterbilt bumpers can be installed with basic tools and mechanical knowledge in 2-4 hours. You'll typically need a socket set, torque wrench, and a helper to support the bumper during installation. Factory mounting holes usually align with aftermarket bumpers, though some drilling may be required for accessories. Common challenges include removing rusted bolts on older trucks and properly aligning fog light wiring. We recommend professional installation if you're adding air ride systems or complex lighting setups.
Will aftermarket bumpers affect my warranty or DOT compliance?
Quality aftermarket bumpers that meet Federal Motor Vehicle Safety Standards won't void your warranty when properly installed. Look for bumpers that maintain factory mounting points and don't modify the frame. For DOT compliance, ensure any added lights meet visibility and height requirements - typically no higher than 42 inches from the ground. Most states allow aftermarket bumpers as long as they don't extend beyond legal width limits (102 inches total vehicle width in most states).
How do I match a new bumper to my existing chrome accessories?
Chrome finishes can vary between manufacturers and production batches. For the best match, try to purchase bumpers and accessories from the same manufacturer and product line. If you have older chrome accessories, a new bumper might appear slightly brighter initially but will typically blend better after a few months of exposure. For stainless steel, look for consistent grain patterns - most quality bumpers use #4 brush finish or mirror polish. When in doubt, order finish samples or visit our showroom to compare options in person.
