Frequently Asked Questions About Mack CX Truck Fuel Tank Accessories

What Mack CX model years are compatible with these fuel tank accessories?

Our fuel tank accessories are designed to fit Mack CX Vision trucks from 2021 to present. These parts are specifically engineered for the CX613 models. If you have an older Mack model like the CHU, CXU, or Granite series, these accessories will not fit properly due to different mounting configurations and tank dimensions. Always verify your truck's VIN and model year before ordering to ensure proper fitment.

Are these fuel tank straps and brackets made from aluminum or steel?

Most of our Mack CX fuel tank straps and mounting brackets are constructed from heavy-duty steel with a corrosion-resistant coating. Steel provides superior strength and durability for supporting heavy fuel tanks, especially in commercial trucking applications. Some decorative accessories like tank covers may feature polished stainless steel or aluminum options. Each product listing specifies the exact material composition, so check the product details for your specific needs.

Do I need special tools or professional installation for fuel tank accessories?

Basic fuel tank strap replacement typically requires standard mechanic tools including socket sets, wrenches, and a floor jack to support the tank during installation. Most drivers with moderate mechanical experience can complete the installation in 1-2 hours. However, we strongly recommend professional installation for any fuel system components that involve fuel line connections or tank removal. Always follow proper safety procedures including draining the tank and working in a well-ventilated area away from ignition sources.

What's the difference between OEM and aftermarket fuel tank straps for my Mack CX?

OEM straps are manufactured to exact Mack specifications and typically cost 30-50% more than quality aftermarket options. Our aftermarket fuel tank straps meet or exceed OEM strength requirements and often feature improved coatings for better corrosion resistance. The main differences are price and sometimes minor variations in finish appearance. Both options will securely mount your fuel tank, but aftermarket parts offer better value without compromising safety or durability.

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

Inspect your fuel tank straps during every pre-trip inspection for signs of rust, cracking, or stretching. Common indicators for replacement include visible corrosion on more than 25% of the strap surface, any cracks in the metal, loose mounting bolts that won't stay tight, or straps that allow excessive tank movement. In northern climates with road salt exposure, straps typically need replacement every 5-7 years. Replace both straps as a set even if only one shows wear to ensure balanced support.
