Freightliner Century 112/120 Dash Knobs

Frequently Asked Questions About Freightliner Century 112/120 Dash Knobs

What do these dash knobs control on the Freightliner Century 112/120?

Dash knobs in this category are used for the interior controls on the dashboard, such as heater and A/C temperature adjustment, fan speed, air vent direction, and defrost or heater controls. Depending on the specific knob, it may thread onto a control shaft or push-fit onto a splined stem behind the dash panel.

Will these knobs fit my specific year Century 112/120?

Freightliner made changes to dash components over the production run of the Century 112/120, so knob shapes, stem sizes, and mounting styles can vary. Check the listed compatible years and control type on each product page, and compare the shaft or stem style of your existing knob before ordering to make sure it matches.

How do I remove and install a replacement dash knob?

Most dash knobs either pull straight off a splined stem or unscrew from a threaded shaft, sometimes secured with a small retaining screw or clip on the front or underside of the knob. Once removed, the new knob typically presses or threads on in the same manner. No special tools are usually required, though a small flathead screwdriver can help release stubborn retaining clips.

What materials and finishes are these knobs available in?

Dash knobs in this category are commonly made from durable plastic or metal, with finishes ranging from chrome-plated to matte black or wood-grain styles to match factory or upgraded interior trim. Metal knobs generally hold up better to repeated use, while plastic options are typically more budget-friendly.

Do these knobs include labels or icons showing their function?

Many replacement knobs include printed or molded symbols and text indicating their function, such as temperature, fan speed, or defrost settings, to match the original dash layout. If a knob is unlabeled or the markings differ from your original, double check the product description or photos before purchasing to confirm it matches the control you are replacing.
