BEFORE YOU ORDER
GOOD QUESTIONS.
STRAIGHT ANSWERS.
A few details make all the difference
when choosing parts for your truck.
How do I know a part fits my truck?
Start with your engine generation, then check the product’s listed years and fitment notes. Pickup and cab & chassis systems can differ. Flange style and mid-year changes also matter. If you’re unsure, send us your year, model, VIN, and the product you’re considering.
What should I have ready for a tuning question?
Send your year, make, model, VIN, current modifications, and the HP Tuners equipment you have. Ask us to confirm ECM access, credit requirements, file scope, and remote assistance before placing an order.
Where do I complete my purchase?
Each product links to its page in the Full Throttle Supply store. Review the complete listing and add it to your cart there. Pricing, availability, shipping, and checkout are confirmed in the store.
Can I ask about shipping, returns, or a warranty?
Yes. Email us with the product link and your question before ordering so we can confirm the details for that item.
