Everything we sell is returnable for full part cost credit within 30 days (except certain special order and discontinued items identified in our catalog as "No Return"). If you're not satisfied with something or you just decide you don't need it, you can obtain return instructions using our Order Status & Returns page or by sending e-mail to service@rockauto.com (in your email, please tell us your order number, the part number and the reason for the return). If a part doesn't fit, don't try to "make it fit" and risk damaging the part or your car (or yourself). We won't accept responsibility for any costs exceeding the cost of the part (and you don't need the aggravation of doing a job twice!) so please inspect the part before you start the repair.

Returns go to different locations, depending on the type of part and the reason for the return. You must send the return to the correct location and include the return instructions in the package to receive credit. Check that the parts are complete and in their original unmarked manufacturer part boxes (cores must be returned in the box the new part came in). Put the part boxes in a shipping box - returns sent in just the manufacturer's packaging may not be refundable if the original box is damaged in shipping. Please don't paint the part, install the part or throw away the box until you're sure the part you have is the part you need! Please do not write on or alter the box in any way. We cannot issue return credit for parts which have been installed, painted, modified or returned without their original packaging.

Shipping charges are not refundable unless the return is due to our mistake. If you decide you don't need a part, we don't mind taking it back but we can't recover the shipping cost. You do have the option of generating a return shipping label for a return from the Order Status & Returns page. The shipping amount will be deducted from your refund. If you refuse delivery or the carrier returns a package because you provided an invalid address, the cost of return shipping will be deducted from your refund.

Refunds typically take up to three business days to be issued. Refunds will be issued in the same form as the original payment (eg, if we received a payment by credit card, then we will issue a refund to that same credit card). Payments excepted from this policy include wire transfers, EFTs (electronic funds transfers), or any other cash payment for which we cannot issue refunds in kind. In these cases, a refund will be issued with a store credit or a U.S./Canadian dollar check. Once a refund has been issued, we send a confirmation by email. Providing us with a return tracking number will ensure a faster refund time. If you entered the return tracking information into the Order Status & Returns page, you do NOT need to email us, as we will already have the tracking information on file.




Some of the parts we sell are remanufactured. These parts are identified in our catalog as "remanufactured" or "reman."

For parts like alternators and master cylinders, the basic body (a complex and expensive metal casting) usually is very durable. But components, like bushings and seals, can wear out and cause the part to fail. Replacing just the worn components can be very cost-effective, helps protect the environment, and produces very reliable results. (Visit Cardone Industries, our primary supplier of remanufactured parts, for more information about remanufacturing.)

Remanufactured parts usually have a core charge. The core charge is a deposit that the manufacturer charges us, and which we pass on to you, to encourage the return of old parts to be remanufactured. You pay the core charge when you place your order. If you return the old part to us, we refund the core charge.

To receive credit, cores (except for complete engines and transmissions) must be returned within six months of the date your order was placed. Complete engine and transmission cores must be returned within 60 days from the date your order is delivered.

Cores must be complete, rebuildable, fit the same vehicle application and be returned in the box the remanufactured part came in. This means the part you send back needs to have whatever components (like pulleys) came on the remanufactured part. The box helps identify the part and proves to the manufacturer that the core replaces one of their products. Obviously, the core won't be working well (or you wouldn't have replaced it) but it can't be smashed, rusted solid, or otherwise unusable. (We rarely reject a core. If the part came off a running vehicle and just wore out--no problem. But please don't send a part that's been soaking in junkyard mud for 5 years and expect to receive core credit!)

Shipping charges on cores aren't refundable. (Before sending back a core, you'll need to decide if the core deposit is worth the shipping cost.) As with any return, before returning a core you must obtain and follow return instructions from our Order Status & Returns page or via email.
