Frequently Asked Questions About Freightliner Century 112/120 Fuel Tank Brackets & Straps

What years and models are these fuel tank brackets compatible with?

These fuel tank brackets and straps are designed specifically for Freightliner Century Class 112 and 120 models manufactured from 1996 through 2010. They fit both single and dual tank configurations. However, compatibility can vary based on your specific tank size (60, 80, 100, or 120 gallon) and mounting setup. We recommend checking your existing bracket measurements or contacting us with your VIN for exact fitment verification.

Are these brackets made of steel or aluminum, and will they rust?

Most aftermarket fuel tank brackets for the Century 112/120 are constructed from heavy-duty steel with either a powder-coated or zinc-plated finish for corrosion resistance. Steel brackets offer superior strength and durability compared to aluminum, especially for supporting heavy fuel loads. The protective coating helps prevent rust, but regular inspection and touch-up of any chips or scratches is recommended, particularly if you operate in areas with road salt or coastal environments.

Do I need special tools or professional installation for these brackets?

Installation typically requires basic hand tools including socket wrenches, a torque wrench, and potentially a floor jack to support the fuel tank during replacement. Most experienced mechanics or fleet maintenance personnel can complete the installation in 1-2 hours per side. However, we strongly recommend professional installation if you're not comfortable working with fuel systems, as improper installation can lead to tank damage or fuel leaks. Always drain the fuel tank before beginning work.

What's the difference between OEM and aftermarket brackets, and which should I choose?

OEM brackets are exact factory replacements that guarantee perfect fit but typically cost 40-60% more than quality aftermarket options. Aftermarket brackets from reputable manufacturers often use the same or improved steel thickness and coating processes while offering better value. The main differences are usually in minor mounting hole variations or finish options. For most applications, a well-made aftermarket bracket will perform equally well and may even outlast the original.

How often should fuel tank brackets be inspected or replaced?

Fuel tank brackets should be visually inspected during every oil change or PM service for signs of cracking, excessive rust, or loose mounting hardware. In normal conditions, quality brackets typically last 7-10 years. However, trucks operating in harsh environments, carrying maximum fuel loads regularly, or showing any signs of metal fatigue should have brackets replaced immediately. Watch for fuel tank shifting, unusual wear patterns on the tank itself, or any separation between bracket components as these indicate immediate replacement is needed.
