Orders ship from the distributor warehouse closest to you, normally within 1–3 business days of purchase. Standard ground delivery takes 3–7 business days in the continental US; expedited options are shown at checkout. Oversized items (bumpers, running boards, large tonneau covers, some marine equipment) ship LTL freight — we contact you to schedule delivery and a signature is required.

Unused, uninstalled parts in original packaging can be returned within 30 days of delivery. A restocking fee of up to 20% may apply depending on the product and supplier, and return shipping is the buyer’s responsibility unless the item arrived defective, damaged or incorrect. Every product carries the full manufacturer warranty. Contact us with your order number to start a return.

Verify fitment with the manufacturer part number shown above and your vehicle’s year, make, model and trim. If the listing says “Fits select…”, confirm your exact application before ordering. Not sure? Send us your VIN and the part number and we’ll check it for you.
