Peterbilt 587 Engine & Performance Parts

Frequently Asked Questions About Peterbilt 587 Engine & Performance Parts

Will these engine and performance parts fit my Peterbilt 587 regardless of engine option?

The Peterbilt 587 was available with different engine configurations depending on model year, so not every part will fit every setup. Always check the listed specifications, including engine make and model year range, before ordering. If you are unsure whether a specific part matches your truck's engine, our team can help you confirm compatibility using your VIN or engine serial number.

What types of components are included in this category?

This category covers parts related to engine performance and operation, such as air intake components, charge air cooler parts, engine brackets and mounts, sensors, gaskets, cooling system components, and other hardware that supports the engine's function. It does not include cosmetic or exterior parts like bumpers or grilles.

Are these parts OEM, aftermarket, or both?

We carry a mix of OEM and quality aftermarket engine and performance parts. Each product listing specifies whether the part is OEM or aftermarket, along with the manufacturer, so you can choose based on your budget and preference for original equipment matching.

Do these parts require professional installation?

Some components, such as sensors, brackets, or gaskets, can be installed by an experienced DIY mechanic with the right tools. However, parts that involve engine timing, fuel systems, or emissions-related components are best installed by a qualified diesel technician to ensure proper function and to avoid compliance issues. If you're unsure about the complexity of a specific installation, we recommend consulting a professional.

Will installing aftermarket performance parts affect my truck's emissions compliance or warranty?

Modifying certain engine components can affect emissions compliance depending on your state and federal regulations, and may also impact any remaining manufacturer warranty. Before purchasing performance-altering parts, check with your engine manufacturer or a compliance professional to confirm the part is legal for on-road use in your area and won't void existing coverage.
