Frequently Asked Questions About Freightliner Cascadia 116/126 Fuel Tank Brackets

What year models of Cascadia 116/126 are these fuel tank brackets compatible with?

Our fuel tank brackets are designed to fit Freightliner Cascadia 116 and 126 models from 2018 to current production years. However, compatibility can vary based on your specific tank configuration (single vs. dual tank setup) and tank size (60, 80, 100, or 120-gallon tanks). We recommend checking your VIN or contacting our customer service team with your truck's specifics to ensure proper fitment before ordering.

Are these brackets made from aluminum or steel, and which is better for my application?

We carry both aluminum and steel fuel tank brackets. Steel brackets are typically more budget-friendly and offer excellent strength for standard applications, though they require regular maintenance to prevent corrosion. Aluminum brackets cost more upfront but provide superior corrosion resistance and weight savings - particularly beneficial for drivers concerned about fuel efficiency and those operating in salt-heavy regions. Most owner-operators prefer aluminum for long-term durability and reduced maintenance.

Can I install these fuel tank brackets myself, or do I need professional installation?

While experienced mechanics can install these brackets with standard shop tools, we recommend professional installation for most customers. The installation typically requires lifting equipment to safely support the fuel tank, torque specifications must be followed precisely (usually 65-75 ft-lbs for mounting bolts), and proper alignment is critical to prevent stress points. Plan for 2-3 hours of labor per side. Many customers report that improper DIY installation led to bracket failure or fuel tank damage.

Do these brackets come with all necessary hardware and straps?

Most fuel tank bracket sets include the brackets themselves but do not include mounting hardware or tank straps, which must be ordered separately. You'll typically need grade 8 bolts, lock washers, and rubber isolators. Tank straps are sold individually and should be replaced whenever you change brackets. We offer complete hardware kits that include all fasteners, bushings, and straps needed for a full installation - check the product description or ask our team about bundling options.

How do I know when my fuel tank brackets need replacement?

Inspect your brackets during every PM service. Replace them immediately if you notice: visible cracks or stress fractures, excessive rust or corrosion (especially at weld points), bent or deformed bracket arms, loose or elongated mounting holes, or damaged rubber isolators. Also watch for signs like fuel tank shifting, unusual vibrations, or strap wear patterns. Most drivers report bracket life of 300,000-500,000 miles under normal conditions, but harsh environments and heavy loads can significantly reduce lifespan.
