Fitment
-
Will this fit my truck?

Shipping
-
When will it ship?
In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.
-
Why did I only get part of my order?

What is the return policy?
30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.
-
How do warranty claims work?
We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.
Paying
-
Can I pay over time?
Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.
-
What is a core deposit?
Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
