Peterbilt 352 Chrome Stacks & Tops

Frequently Asked Questions About Peterbilt 352 Chrome Stacks and Exhaust Stack Tops

What chrome stack diameter fits a Peterbilt 352?

Peterbilt 352 chrome stacks commonly use 5-inch or 6-inch exhaust stack diameters, with 5-inch stacks being the most common factory-style size. Exact stack diameter depends on your truck?s current exhaust pipe size, stack base, clamps, elbows, reducers, and exhaust routing.

To choose the correct Peterbilt 352 chrome stack size, measure the inside diameter of the existing exhaust pipe or stack base. If you are upgrading from one diameter to another, such as from a 5-inch stack to a 6-inch stack, you may need the correct reducer, adapter, exhaust clamp, or modified mounting bracket.

Will these chrome stacks fit my Peterbilt 352?

Peterbilt 352 chrome stacks and exhaust stack tops are designed to fit select 1979?1987 Peterbilt 352 cabover truck models. Exact fitment depends on model year, exhaust diameter, single or dual exhaust configuration, stack length, cab clearance, mounting brackets, elbows, and existing exhaust routing.

Some mid-1985 and newer Peterbilt 352 trucks may have different exhaust routing that requires additional elbows, extensions, clamps, or custom alignment. Before ordering, verify your truck?s model year, current stack diameter, exhaust layout, mounting bracket locations, and whether the truck uses a single exhaust or dual exhaust setup.

Can I install Peterbilt 352 chrome stacks myself?

Many Peterbilt 352 chrome stacks can be installed with standard hand tools and moderate mechanical experience. Typical installation may take 2 to 3 hours when the existing exhaust system, clamps, and brackets are in good condition.

Common tools and supplies may include wrenches, a socket set, exhaust clamps, high-temperature exhaust sealant, and possibly a reciprocating saw if old stacks or damaged exhaust sections need to be removed. Some Peterbilt 352 exhaust stack installations may require additional elbows, flex pipe, reducers, extensions, or bracket adjustments if the new chrome stacks do not align with the current exhaust routing.

What additional parts may I need when replacing Peterbilt 352 chrome stacks?

When replacing Peterbilt 352 chrome stacks, you may need exhaust clamps, reducers, adapters, elbows, flex pipe, extensions, mounting brackets, or high-temperature exhaust sealant. The required parts depend on your existing exhaust system and whether you are keeping the same stack diameter or changing to a larger size.

If your Peterbilt 352 has older, rusted, modified, or custom exhaust components, inspect the stack bases, brackets, clamps, elbows, and connection points before ordering. Professional installation is recommended if cutting, welding, exhaust routing changes, or custom fabrication is required.

What is the difference between straight chrome stacks and curved chrome stacks for a Peterbilt 352?

Straight chrome stacks give a Peterbilt 352 a classic vertical exhaust appearance and are often easier to align with existing exhaust brackets. Curved chrome stacks, sometimes called bull horn stacks or turn-out stacks, create a more custom look and can help direct exhaust away from the cab area.

For Peterbilt 352 cabover trucks, many drivers choose 36-inch to 48-inch straight stacks or moderately curved stacks because the cabover design has less space behind the cab than many long-hood conventional trucks. Curved stack tops should angle away from the cab with enough clearance to reduce soot buildup, heat exposure, and exhaust residue near the cab surface.

What chrome stack length works best on a Peterbilt 352?

Peterbilt 352 chrome stack lengths commonly range from 36 inches to 48 inches, although the best length depends on exhaust routing, cab clearance, bracket location, and the desired appearance. Shorter stacks may be easier to fit on a cabover truck, while taller stacks can create a more traditional big-rig look.

Before choosing a stack length, check clearance around the cab, roofline, brackets, body components, and any overhead obstacles. The stack should be tall enough to route exhaust safely but not so tall that it creates clearance issues or requires major bracket modification.

How do I maintain the chrome finish on Peterbilt 352 exhaust stacks?

Peterbilt 352 chrome exhaust stacks should be washed regularly with mild soap and water, then polished with a quality chrome polish to help maintain a bright mirror finish. Avoid abrasive cleaners, harsh pads, or coarse steel wool because they can scratch the chrome surface.

For trucks used in winter weather or salt-treated areas, wash chrome stacks more frequently to remove road salt and grime. A chrome wax or protective polish can help reduce corrosion risk and preserve shine. Some dulling, bluing, or discoloration near high-heat areas may occur over time because exhaust stacks are exposed to heat, soot, moisture, and road debris.

What are Peterbilt 352 chrome stacks made from?

Peterbilt 352 chrome stacks are commonly made from steel with chrome plating or stainless steel with a polished chrome-like finish, depending on the product. Chrome-plated steel stacks provide a bright custom appearance but require regular maintenance to help prevent rust, pitting, and surface dulling.

Polished stainless steel stacks generally provide stronger corrosion resistance than chrome-plated steel and may require less maintenance in harsh weather conditions. Always check the product listing for the exact material, finish, wall thickness, diameter, and stack style before ordering.
