Peterbilt 357/378 Custom Pedals

Frequently Asked Questions About Peterbilt 357/378 Custom Pedals

Will these custom pedals fit my Peterbilt 357 or 378 without modification?

These pedals are designed to work with the factory pedal assemblies on Peterbilt 357 and 378 models, typically replacing or covering the stock gas, brake, and clutch pedal pads. Because pedal setups can vary slightly by production year and cab configuration, it is a good idea to compare the mounting pattern or pedal shape of the product to your truck before ordering, or reach out to our team to confirm fitment for your specific year.

What materials are these pedals made from, and how durable are they?

Most custom pedals in this category are constructed from heavy-duty aluminum or stainless steel, often featuring a diamond-plate or textured surface for added grip. These materials are chosen to hold up under daily use in a working truck cab, resisting wear from boots, moisture, and road grime better than factory rubber pedal pads.

Do these pedals provide better grip than the factory pedals, especially in wet or muddy conditions?

Yes, one of the main reasons drivers upgrade to custom pedals is improved traction. The textured or diamond-plate surfaces on these pedals are designed to offer a more secure footing than worn factory rubber pads, which can become slick over time or in wet weather.

How difficult is it to install these pedals, and what tools do I need?

Installation is generally straightforward and can often be done with basic hand tools such as a screwdriver, wrench, or drill, depending on whether the pedal is a bolt-on cover or a full replacement piece. Most drivers can complete installation in under an hour without needing a shop visit, but if you are replacing an entire pedal assembly rather than adding a cover, allow extra time and consult the product instructions.

Are these pedals available in different finishes or styles to match my interior?

Yes, custom pedals for the 357 and 378 typically come in a few finish options, such as polished stainless steel or brushed aluminum, and some feature laser-cut logos or unique tread patterns. This allows you to choose a look that complements the rest of your custom cab accessories while still getting a functional upgrade.
