Finding Parts for Your Diesel Truck
Buying aftermarket diesel parts only works if you actually know what engine is under your hood. Instead of making you scroll through endless pages, the store splits everything into three main groups: Ford Powerstroke, Ram Cummins, and GM Duramax. Pick your engine family first. After that, you can filter down to specific parts like EGR, DPF, and CCV kits, or intake and exhaust pipes.
Double-Checking Fitment
Duramax owners can narrow things down even more by picking their exact engine generation, like LB7, LLY, LBZ, LMM, LML, or L5P. Most product titles also show the model years and tell you if a part fits a 2500 or 3500 HD truck. Don't just order based on the general engine name. Check those extra details in the title so you don't end up stuck with the wrong kit.
If you drive a Cummins, the site has a few blog posts that explain 6.7 Cummins EGR and DPF setups. You can also open their installation manuals right on the site to see how much work a project takes before you buy anything.
Shipping and Return Policies
US orders over $50 get free shipping. Packages usually arrive in 2 to 7 business days after they ship out.
If you need to return something, email their support team first to get started. Unused parts in their original box can go back within 60 days, though custom items cannot be returned. Just keep in mind that you pay for the return shipping label, plus a 10% handling fee.
(Note before publishing: The homepage mentions a 30-day return window, while the policy page says 60 days. Check which one is right before this goes live.)
Discounts and Legal Notes
Like most emissions gear, these parts are made for off-road and competition use only. It is on you to follow your local emissions laws before putting them on a street truck.

What does 9PHX RACING sell?
It sells aftermarket performance parts for diesel trucks, mainly EGR, DPF and CCV delete kits, intake pipes and exhaust race pipes, organized by Powerstroke, Cummins and Duramax engines.
How do I know if a part fits my truck?
Product titles list model years, engine codes and weight classes, so match those details to your truck before ordering. Many listings offer option menus, and an installation manual is available for download. For fitment questions, the site lists email and online chat support.
Are these parts legal for street use?
The site labels its products for off-road and competition use only and says buyers are responsible for complying with local laws. Check your local and federal regulations before ordering.
Does 9PHX RACING offer free shipping, and what is the return policy?
Free shipping applies to U.S. orders over $50, and U.S. delivery typically takes 2 to 7 business days after shipment. The Return & Refund Policy accepts requests within 60 days of delivery for unused items in original packaging, with buyers paying return shipping plus a 10% handling fee. The homepage banner mentions 30 days, so confirm the window with the store before ordering.
