Frequently Asked Questions About Peterbilt 330/335/337 Chrome Stacks & Tops

Will these chrome stacks fit my specific Peterbilt 330, 335, or 337 model year?

Most chrome stacks and tops in this category are designed to fit Peterbilt 330, 335, and 337 models from 2005 to present. However, there can be variations based on your truck's specific configuration, such as cab style and exhaust system setup. We recommend checking the product description for exact year ranges or contacting our customer service team with your VIN number to ensure proper fitment before ordering.

What's the difference between 304 and 430 stainless steel chrome stacks?

304 stainless steel offers superior corrosion resistance and maintains its chrome finish longer, making it ideal for trucks operating in harsh weather conditions or coastal areas. 430 stainless steel is more budget-friendly and still provides good durability for most applications. Both grades polish to a mirror finish, but 304 typically stays shinier with less maintenance over time.

Do I need special tools or professional installation for these chrome stacks?

Basic installation typically requires standard hand tools including wrenches, socket sets, and possibly a drill for mounting brackets. Most stacks come with clamps and mounting hardware. While many drivers successfully install these themselves in 1-2 hours, some configurations may require cutting or modification of existing exhaust pipes. If you're not comfortable with exhaust work, we recommend professional installation to ensure proper fit and avoid exhaust leaks.

What stack diameter and length should I choose for my Peterbilt medium-duty truck?

The most common diameters for Peterbilt 330/335/337 models are 5-inch and 6-inch, with 5-inch being standard on most factory configurations. Stack length typically ranges from 36 to 60 inches, with 48 inches being the most popular choice. Consider your truck's primary use - shorter stacks (36-48 inches) work better for urban delivery and low clearance areas, while longer stacks (48-60 inches) provide a more traditional look and better exhaust dispersion for highway applications.

How do I maintain the chrome finish and prevent discoloration from exhaust heat?

Regular cleaning with a quality chrome polish every 2-4 weeks helps maintain the mirror finish. For heat discoloration (bluing) near the base, use a specialized chrome exhaust cleaner or fine steel wool with polish. Installing a heat shield or wrap on the first 12-18 inches can prevent excessive discoloration. Avoid using abrasive cleaners or coarse materials that can scratch the chrome surface. During winter months, rinse stacks frequently to remove road salt and prevent pitting.
