Frequently Asked Questions About Peterbilt 567/579 Chrome Stacks & Tops
Will these chrome stacks fit my specific Peterbilt 567 or 579 model year?
Most chrome stacks and tops are designed to fit Peterbilt 567 and 579 models from 2013 to present. However, there can be variations based on your truck's configuration, such as sleeper size and exhaust routing. We recommend checking your current stack diameter (typically 5" or 6") and measuring the mounting bracket spacing before ordering. If you're unsure, contact us with your VIN and we'll help verify compatibility.
What's the difference between 304 and 430 stainless steel stacks, and which should I choose?
304 stainless steel contains nickel and offers superior corrosion resistance and shine retention, making it ideal for trucks exposed to road salt and harsh weather. 430 stainless is more affordable but may show surface rust over time in corrosive environments. For trucks operating in northern states or coastal areas, we strongly recommend 304 stainless. Southern and western operators often find 430 adequate for their needs.
How difficult is the installation, and what tools will I need?
Installation typically takes 2-4 hours depending on your experience level. You'll need basic hand tools including socket wrenches, a torque wrench, and potentially a sawzall if you're replacing existing stacks. The main challenges include properly aligning the stacks for a symmetrical appearance and ensuring exhaust clamps are tight enough to prevent leaks without crushing the pipe. Many customers successfully complete this as a weekend project, though professional installation is available at most truck shops.
What stack styles work best for my application - straight cut, curved, or mitered?
Straight cut stacks provide a classic, professional appearance and are easiest to maintain. Curved or bull hauler styles offer better rain protection and a distinctive look but may require more frequent cleaning. Mitered (angled) cuts provide moderate rain protection while maintaining a sleek profile. Consider your typical routes - drivers in wet climates often prefer curved tops, while those in drier regions typically choose straight or mitered for easier maintenance.
How do I maintain the chrome finish and prevent discoloration?
Chrome stacks require regular maintenance to prevent bluing and discoloration from exhaust heat. Clean them every 2-3 weeks with a quality chrome polish and microfiber cloth. For stubborn exhaust stains, use a specialized chrome cleaner with mild abrasives. Avoid harsh chemicals or steel wool which can scratch the finish. Installing a heat shield wrap on the lower portion can significantly reduce discoloration. During winter months, rinse road salt off weekly to prevent pitting.
