Frequently Asked Questions

How do I know a part will fit my truck?
Every product page lists the makes and models the part fits. Filter by your truck from the top of any category page, or call our parts team and we will confirm the fit before you order.
What is covered by your 180-day return policy?
Most eligible purchases can be returned within 180 days of purchase, provided the product is new, unused, uninstalled, clean, in its original packaging, and 100% resalable. Drop-ship, non-stocking, special-order, clearance, custom-built items, and electronics are excluded from the standard return policy. See our Return & Refund Policy for complete details and return requirements. 
Do you offer financing on large orders?
Yes. 4 State Trucks offers financing through Bread Pay™, allowing you to pay for eligible purchases over time with monthly payment options and competitive interest rates. There are no prepayment penalties, and you can check your rate in seconds without affecting your credit score. Financing is subject to credit approval. Learn more about 4 State Trucks financing.
When will my order ship, and how long will it take to arrive?
Shipping times vary depending on product availability and lead time. Special-order items may require additional processing time. For the most up-to-date status and estimated delivery information, track your order here. You can also call a 4 State Trucks Parts Pro at 888-875-7787 for assistance with your order.
What is the difference between OEM and aftermarket parts?
OEM (Original Equipment Manufacturer) parts are made by the truck’s original manufacturer or an approved supplier and are designed to match the vehicle’s original specifications. Aftermarket parts are made by third-party manufacturers and may offer different features, styles, or price points. Both can be quality options, depending on your truck, application, and needs. If you’re unsure which part is right for your truck, call a 4 State Trucks Parts Pro at 888-875-7787 for more information.
