Front Lower Control Arm (Right) for BYD Dolphin, OE 13127917-00

This is listed as the right side front lower control arm. Before you order, check the old arm you have taken off the car and match the OE number, 13127917-00, against what is stamped or printed on it. If the numbers match you have the correct side. If you cannot find a number on the old part, hold it next to a picture or diagram of the correct side arm so you can compare the shape and mounting points before you commit to the order.

Original/Genuine means the part comes from BYD, the maker of the car. Aftermarket is made by another manufacturer to the same fitting and function, without the maker's branding. Have a look at the photographs on this page to see exactly which tier this listing shows, including any markings, so you know precisely what you are ordering. Choosing between the two comes down to whether you want the maker's own part or an aftermarket equivalent that fits and works the same way.

If the number stamped on your old control arm does not match OE 13127917-00, do not order on the number alone. Check instead which side of the car it is fitted to, whether it sits at the front, and how the fixings line up with your own car. That comparison of side, position and fixings tells you more than the number on its own. If you are still unsure after checking those three points, it is worth confirming before you order rather than after the part has arrived.

That is not something we can tell you from here. What we can tell you is that this arm is also listed under the reference EM2E-2904020, so if you are checking it against a workshop manual or a parts catalogue that uses that number instead of the OE number, you are looking at the same component. Match it against the number on the old part before you order, using either reference, to be certain it is the right one for your Dolphin.

Allow 8 to 28 days for delivery, counted from your order to your door. Use that window to get ready rather than waiting idle, starting with the number stamped on the part you are taking off the car. Checking that stamped number now, before the new arm turns up, means you can confirm it matches OE 13127917-00 as soon as the box is opened, instead of discovering a mismatch after the old part is already off the car.

This is a metal arm, so it carries the weight of the corner without flexing, but a knock hard enough to bend it will not straighten back true and the part should be replaced rather than reshaped. Before you order, pull out your registration document and check the model and the model year printed on it. That is the detail that decides whether this arm is the right one for your Dolphin, so have it in front of you when you place the order.
