Frequently Asked Questions About Kenworth T680 Chrome Stacks & Tops

Will these chrome stacks fit my specific year model Kenworth T680?

Most chrome stacks and tops in this category are designed to fit Kenworth T680 models from 2013 to present. However, there can be slight variations between model years, particularly with mounting bracket positions. We recommend checking the product description for specific year compatibility or contacting our support team with your VIN to ensure proper fitment. Note that pre-2017 models may require different mounting hardware than 2017+ models.

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 or coastal environments. 430 stainless steel is magnetic, more affordable, and provides good durability for most conditions but may show slight discoloration over time in harsh environments. For maximum longevity and appearance, we recommend 304 stainless, but 430 is a solid choice for budget-conscious buyers in moderate climates.

Can I install these chrome stacks myself, or do I need professional installation?

Most chrome stacks can be installed with basic tools and mechanical knowledge in 2-4 hours. You'll typically need a socket set, torque wrench, and possibly a drill for certain mounting brackets. The main challenges include proper alignment, securing heavy stacks safely during installation, and ensuring exhaust connections are properly sealed. We provide detailed instructions with each product, but if you're uncomfortable working with exhaust systems or lifting heavy components, professional installation is recommended.

What stack heights and diameters are available, and how do I choose the right size?

Chrome stacks typically come in 5-inch, 6-inch, and 7-inch diameters, with heights ranging from 36 inches to 72 inches. The diameter must match your existing exhaust pipe size - most T680s use 5-inch systems. Height selection depends on your preference and local regulations. Taller stacks (60-72 inches) provide a classic look but may have clearance issues with bridges or loading docks. Shorter stacks (36-48 inches) offer a sportier appearance and better maneuverability.

How do I maintain the chrome finish and prevent discoloration or rust?

Regular maintenance is key to preserving your chrome stacks' appearance. Clean them every 2-4 weeks with a quality chrome polish and microfiber cloth. For stubborn exhaust stains, use a specialized chrome cleaner or fine steel wool (0000 grade only). Apply a chrome sealant or wax every 3 months to protect against moisture and road chemicals. Avoid harsh chemicals, abrasive cleaners, or power washing directly on the chrome surface. Address any surface rust immediately with chrome polish to prevent spreading.
