Kenworth T800 Engine & Performance Parts

Frequently Asked Questions About Kenworth T800 Engine & Performance Parts

Will these engine and performance parts fit my specific Kenworth T800 model year and engine?

The Kenworth T800 was produced over many years with several engine options, including various Caterpillar, Cummins, and PACCAR engines depending on the model year. Fitment can vary significantly based on your truck's specific engine model and configuration, so it's important to check the listed compatibility details on each product page or contact our parts specialists with your VIN or engine serial number before ordering.

Are these parts OEM, aftermarket, or a mix of both?

This category includes a combination of OEM and quality aftermarket 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 versus a comparable replacement option.

How do I know if a part is a direct replacement for the one currently on my truck?

We recommend comparing part numbers whenever possible, as this is the most reliable way to confirm a direct match. If your old part is damaged or the number is unreadable, our team can help you identify the correct replacement using your truck's engine and chassis information.

Do engine and performance parts in this category require professional installation?

Some components, such as sensors, gaskets, or smaller hardware, may be manageable for experienced DIY mechanics with the right tools. However, many engine performance parts involve more involved procedures, torque specifications, or system calibration, so we recommend professional installation for these items to help ensure proper performance and longevity.

What kind of warranty coverage do these parts typically come with?

Warranty terms vary by manufacturer and by whether the part is OEM or aftermarket. Details on coverage length and what is included are listed on individual product pages. If you don't see the warranty information you need, our customer service team can look up the specifics for you before you purchase.
