Performance FAQ
What performance parts should I start with on a diesel truck?
Many owners start with supporting parts such as a lift pump, air intake and gauges, then move to turbo and fuel system upgrades. Your goals for towing, mileage or power should guide the plan.
Are diesel performance parts emissions legal?
It depends on the part. Many diesel performance parts are sold for off-road or competition use only and are not legal on emissions-controlled vehicles driven on public roads. Check the product page and your state and federal rules before you buy.
How do I know a part fits my truck?
Each product page lists the vehicles it fits. If you are not sure, call (806) 503-2161 or use the contact form with your truck's year, make, model and engine, and we'll confirm fitment before you order.
