Frequently Asked Questions About Freightliner Coronado Chrome Stacks & Tops

What are the differences between 304 and 430 stainless steel stacks, and which should I choose?

304 stainless steel contains nickel and offers superior corrosion resistance, making it ideal for harsh weather conditions and coastal areas. It maintains its shine longer but comes at a higher price point. 430 stainless steel is magnetic and more affordable, providing good appearance but may show surface rust over time, especially in salt-heavy environments. For maximum longevity and minimal maintenance, we recommend 304 stainless. Choose 430 if you're on a budget and operate primarily in dry climates.

Will these stacks fit my specific Freightliner Coronado model year?

Our chrome stacks are designed to fit Freightliner Coronado models from 2002 to present. However, there are slight variations between pre-2010 and post-2010 models in mounting bracket positions. Classic Coronado (2002-2009) models use a standard 5-inch or 6-inch diameter with specific bracket spacing, while newer SD and 122SD models (2010+) may require different mounting hardware. Always verify your truck's exact model year and current exhaust configuration before ordering. Contact our support team with your VIN if you need assistance confirming compatibility.

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 (typically 9/16" and 5/8"), a torque wrench, and potentially a sawzall if cutting is required. Most installations involve removing the old stack, transferring or installing new clamps and brackets, and securing the new stack. Common challenges include aligning brackets properly and achieving the correct angle. Professional installation runs $150-300 if you prefer not to DIY. We include detailed instructions with each purchase.

What stack styles and finishes are available, and how do they differ in appearance?

We offer straight cut, curved, miter cut, and bull hauler styles in chrome finishes. Straight cut provides a classic, clean look and is most popular. Curved stacks direct exhaust away from the trailer and reduce cab soot. Miter cuts offer an aggressive angled appearance. Bull hauler styles feature expanded ends for that traditional long-haul aesthetic. Chrome finishes include standard polish, mirror finish, and powder-coated options. Mirror finish requires more maintenance but provides the brightest shine. Standard polish offers good appearance with easier upkeep.

How do I maintain chrome stacks to prevent discoloration and pitting?

Regular maintenance is crucial for preserving chrome appearance. Wash stacks weekly with mild soap and water, especially if operating in winter conditions with road salt. Apply a quality metal polish monthly, and use a chrome-specific sealant every 3-4 months. Avoid harsh chemicals or abrasive materials. For existing discoloration, use a specialized chrome restoration product with fine steel wool (0000 grade). Interior heat shields help prevent blueing from exhaust heat. Expect to spend 15-20 minutes per stack for proper maintenance. Neglected chrome can develop permanent pitting within 6-12 months in harsh conditions.
