Kenworth W900B/W900L Frame Steps & Acc.

Frequently Asked Questions About Kenworth W900B/W900L Frame Steps & Acc.

What are frame steps and what do they do?

Frame steps are step assemblies that mount directly to the truck's frame rail, giving drivers a stable foothold for entering the cab, accessing the fuel tanks, or reaching the back of the hood for daily inspections and maintenance. They are a common replacement or upgrade item since steps see constant wear from weather, road debris, and everyday use.

Will these frame steps fit my specific W900B or W900L?

Fit can vary depending on frame rail height, tank placement, and whether your truck has factory or aftermarket brackets already installed. Because the W900B and W900L can be configured differently from the factory and may have been modified over time, we recommend checking listed measurements and mounting hole patterns against your truck, or reaching out to our sales team with your VIN or existing part details before ordering.

What materials and finishes are available?

Frame steps in this category are typically offered in aluminum or steel construction, with finish options such as plain, polished, or chrome-plated depending on the specific product. Aluminum steps tend to resist corrosion well and are lighter, while steel and chrome options are often chosen for durability and a more finished appearance. Product listings will specify the exact material and finish for each item.

What's involved in installing a frame step?

Most frame steps bolt on using existing mounting holes in the frame rail or included brackets, so installation generally does not require welding. That said, exact hardware and mounting configurations differ by product, so it's a good idea to review the included instructions or contact us if you're unsure whether a step will bolt straight on or need modification.

How do I know if a step needs to be replaced versus repaired?

If a step is cracked, bent, badly rusted, or has broken welds on the mounting bracket, replacement is the safer option rather than attempting a repair, since a compromised step can fail under weight. Loose or wobbly steps caused by worn hardware can sometimes be fixed by simply replacing bolts or brackets rather than the entire step, so it's worth inspecting the mounting points first.
