Frequently Asked Questions About Peterbilt 387 Engine & Performance Parts

Will these engine and performance parts fit my specific Peterbilt 387?

The Peterbilt 387 was built with a few different engine options over its production run, so fitment can vary depending on your truck's engine model and year. Before ordering, check your engine's make and model against the product specifications listed on each part page, or reach out to our team with your VIN or engine details so we can confirm compatibility before you buy.

What types of components are included in this category?

This category covers parts related to your Peterbilt 387's engine performance and operation, including items such as air intake components, exhaust and emissions-related hardware, cooling system parts, sensors, gaskets, belts, and other components that support engine function and efficiency. Browse the category listings to see the full range of parts currently available.

Are these parts OEM, aftermarket, or both?

We carry a mix of OEM and quality aftermarket parts for the Peterbilt 387. Each product listing specifies the brand and part type so you can decide whether you want a factory-matched replacement or an aftermarket alternative. If you have a preference or need help choosing, our team can point you toward the right option for your budget and application.

Do I need professional installation, or can I install these parts myself?

It depends on the part. Some components, like belts, filters, or sensors, are straightforward enough for an experienced DIY mechanic to install with basic tools. Others, particularly those involving emissions systems or major engine components, may require specialized tools, diagnostic equipment, or professional certification to install correctly and keep your truck compliant. If you're unsure about a specific part, check the product description or consult a qualified diesel technician before starting the job.

How do I know if a part will help with performance or fuel efficiency versus just being a standard replacement?

Product descriptions on each listing indicate whether a part is a standard replacement component or one designed to improve performance, airflow, or fuel economy. If you're shopping specifically for performance upgrades rather than routine maintenance parts, look for details in the title and description, or contact us directly and we can help you find parts suited to your goals.
