Peterbilt 587 Dash Knobs

Frequently Asked Questions About Peterbilt 587 Dash Knobs

What are Peterbilt 587 dash knobs used for?

These knobs are replacement or upgrade controls for the dashboard switches and levers inside the Peterbilt 587, such as headlight switches, HVAC controls, and other dash-mounted functions. They are designed to fit the factory dash layout and replace worn, cracked, or missing knobs.

Will these knobs fit my specific Peterbilt 587 dash configuration?

Dash knobs are typically designed to match the stem size and shape used on the Peterbilt 587, but dash layouts can vary slightly depending on model year and factory options. We recommend comparing the knob style and stem dimensions to your existing part, or checking the fitment notes on each product listing before ordering.

What materials and finishes are available?

Dash knobs are commonly offered in materials like chrome-plated plastic, billet aluminum, or durable molded plastic, depending on the style. Finish options often include chrome, brushed metal, and black or color-matched plastic to complement different interior setups.

How do I install a replacement dash knob?

Most dash knobs simply pull, twist, or unscrew off the existing switch stem, and the new knob presses or threads back into place. No wiring or electrical work is typically required since the knob is a cosmetic and functional cover, not the switch itself. If a knob is held on with a small screw or pin, a small screwdriver may be needed for removal.

Will installing a new dash knob affect any electrical or warning systems?

No. Dash knobs are non-electrical components that attach to the existing switch or lever mechanism, so replacing one does not affect your truck's wiring, warning lights, or electrical systems. They are strictly a functional and cosmetic upgrade for the control itself.
