Will these chrome stacks fit my specific Peterbilt 379 model year?
Most chrome stacks and tops are designed to fit Peterbilt 379 models from 1987-2007. However, there can be variations based on whether you have an extended hood, short hood, or custom modifications. We recommend checking the product description for specific year compatibility or calling our team with your VIN number to ensure proper fitment. Pay special attention to mounting bracket compatibility if your truck has aftermarket exhaust modifications.
What's the difference between 304 and 430 stainless steel stacks?
304 stainless steel contains nickel and offers superior corrosion resistance and durability, maintaining its chrome-like shine longer with minimal maintenance. 430 stainless steel is magnetic, costs less, but may develop surface rust over time, especially in harsh weather conditions. For trucks operating in salt-heavy regions or those wanting long-lasting shine, we recommend 304 stainless. Both options provide that classic chrome appearance when new.
Can I install chrome stacks myself, or do I need a professional?
Installation typically takes 2-4 hours and requires basic mechanical skills. You'll need standard tools including wrenches, a drill for any new mounting holes, and possibly a sawzall for trimming existing exhaust pipes. The main challenges include proper alignment, securing heavy stacks (some weigh 30+ pounds), and ensuring exhaust-tight connections. Many drivers successfully install these themselves, but if you're uncomfortable with exhaust work or need to modify existing piping, professional installation runs $200-400.
What stack styles look best on a 379, and what sizes are available?
The most popular styles for Peterbilt 379s are straight pipes, curved tops, and miter-cut designs. Common diameters range from 5 inches to 7 inches, with 6-inch being the most popular for that classic look. Heights typically range from 36 inches to 72 inches. Straight pipes offer a traditional appearance, while curved tops help direct exhaust away from the cab. Bull hauler styles with expanded ends are also popular. Consider your overall truck height and any bridge clearance issues when selecting stack height.
How do I maintain chrome stacks to prevent discoloration and rust?
Chrome stacks require regular maintenance to keep their mirror finish. Clean them every 2-3 weeks with chrome polish and a microfiber cloth. For stubborn exhaust stains, use fine steel wool (0000 grade) with polish. Apply a quality metal sealant or wax monthly to protect against moisture and road chemicals. Avoid harsh chemicals or abrasive cleaners. If you notice blueing from heat, specialized chrome restoration products can help. In winter climates, increase cleaning frequency to remove road salt promptly.
