Peterbilt 587 Toggle Extensions

Frequently Asked Questions About Peterbilt 587 Toggle Extensions

What are toggle extensions and what do they do?

Toggle extensions are dash panel accessories designed to extend or fill the switch panel area on your Peterbilt 587, giving you additional mounting space for aftermarket toggle switches. They allow you to add extra switches for accessories like lights, fans, or other electrical add-ons without cutting into your existing dash panel.

Will these fit my Peterbilt 587 without modification?

These toggle extensions are built specifically for the Peterbilt 587 dash layout, so they are designed to align with the factory switch panel and mounting points. In most cases no cutting or drilling is required, but fitment can vary slightly depending on the model year and any prior dash modifications, so it is a good idea to check panel dimensions before ordering.

What materials and finish options are available?

Toggle extensions are typically offered in materials such as stainless steel or durable ABS plastic, with finish options ranging from brushed or polished stainless to painted or textured black finishes. Choosing a finish that matches your existing dash trim helps keep the interior looking factory-clean.

How many additional switches can I add with an extension panel?

The number of switch openings varies by product, with most extensions offering room for anywhere from a few to a dozen additional toggle or rocker switches. Be sure to check the specific hole count and switch size compatibility listed on each product page before purchasing.

Do these come with switches, wiring, or mounting hardware included?

Most toggle extensions are sold as blank panels or pre-cut panels only, meaning switches, wiring, and electrical connections are typically not included. Mounting hardware is usually provided, but you should plan on sourcing your own switches and wiring or having a professional install them if you are not comfortable with basic electrical work.
