Frequently Asked Questions About Kenworth T700 Engine & Performance Parts

Will these engine and performance parts fit my specific Kenworth T700, regardless of engine make?

The Kenworth T700 was offered with different engine options depending on model year, so it's important to confirm your truck's specific engine make and model before ordering. We recommend checking your engine's ID tag or referencing your owner's manual for exact specifications, and comparing that information against the fitment details listed on each product page. If you're unsure, our parts team can help verify compatibility before you buy.

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

Our Kenworth T700 engine and performance parts inventory includes both OEM and quality aftermarket options. Each product listing specifies the manufacturer and part type, so you can choose based on your preference for original equipment matching or a more budget-friendly aftermarket alternative. If a listing doesn't clearly state which category a part falls into, feel free to reach out and we'll clarify before you purchase.

Do these components require professional installation?

Installation complexity varies by part. Some items, like sensors, filters, or small hardware components, can be installed with basic tools and mechanical knowledge. Others, such as turbochargers, injectors, or major engine components, typically require professional installation and proper diagnostic equipment to ensure correct fitment and performance. If you're not experienced with diesel engine work, we recommend having a qualified diesel technician handle installation for these more involved parts.

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

This depends on the specific part and your engine's warranty terms. Modifications to emissions-related components can affect compliance with federal and state regulations, and may impact manufacturer warranty coverage. Before installing any performance-enhancing parts, check your engine's warranty documentation and confirm the part is legal for on-road use in your operating region. When in doubt, consult with your engine manufacturer or a trusted diesel shop.

How do I know if a part is worn out and needs replacing versus repairing?

Common signs that indicate a part needs replacement include reduced power, unusual engine noises, increased fuel consumption, visible leaks, or diagnostic trouble codes. Some components, like gaskets or seals, are generally more cost-effective to replace outright rather than repair. If you're seeing performance issues, a diagnostic scan combined with a physical inspection is the best way to determine whether replacement is necessary. Our team is available to help you identify the right replacement part once you've pinpointed the issue.
