Frequently Asked Questions About Freightliner Century 112/120 Frame Steps & Acc.

Will these frame steps fit my specific Freightliner Century model year?

Frame steps for Freightliner Century 112/120 models typically fit trucks manufactured from 1996 to 2011. However, there are variations between early models (1996-2004) and later models (2005-2011) due to frame rail spacing changes. Always verify your truck's exact year and measure the frame rail width before ordering. Most universal steps are adjustable between 34" to 42" to accommodate different configurations.

What's the difference between aluminum and steel frame steps, and which should I choose?

Aluminum steps are lighter (typically 15-20 lbs per set), resist corrosion better, and won't rust, making them ideal for drivers in salt-heavy regions or those concerned about weight. Steel steps are heavier (25-35 lbs per set) but generally cost 20-30% less and offer superior strength for heavy-duty use. Both materials support 300-500 lbs when properly installed. Choose aluminum for longevity and appearance, steel for budget and maximum durability.

Can I install these frame steps myself, or do I need professional help?

Most frame steps can be installed with basic tools in 1-2 hours. You'll need a drill with metal bits, wrenches, and possibly a rivet gun depending on the mounting style. Many drivers report successful DIY installation, but challenges include drilling through thick frame rails and ensuring proper alignment. If your truck has aftermarket fuel tanks or custom exhaust routing, professional installation may be necessary to avoid interference.

What finish options are available, and how do they hold up over time?

Common finishes include polished aluminum, chrome-plated steel, powder-coated black, and bare aluminum. Polished aluminum requires regular cleaning but won't peel or chip. Chrome provides the shiniest appearance but may show pitting after 3-5 years in harsh conditions. Powder-coated finishes offer excellent durability and hide scratches well, lasting 5-7 years with minimal maintenance. Bare aluminum develops a natural patina that many drivers prefer for its low-maintenance appeal.

How do I ensure the steps won't interfere with my fuel tanks or other frame-mounted accessories?

Before ordering, measure the clearance between your frame rails and any tanks, boxes, or exhaust components. Most frame steps extend 4-6 inches from the rail and require at least 8 inches of vertical clearance. Steps with adjustable brackets offer more flexibility for trucks with aftermarket modifications. Some models feature offset mounting options specifically designed to clear common 50-70 gallon fuel tank configurations on Century trucks.
