Front Coil Spring for BYD Seal 05 DM-i & Qin PLUS DM-i, OE 12657364-00

Both are right. HAD-2905311 is an alternative reference for OE 12657364-00, so a spring carrying that marking is the same part as the one on this page. Markings on springs are often the supplier reference rather than the vehicle manufacturer number, which is why we publish the pair. Read whatever you can find on the old spring and check it against both. If neither matches, send a photograph of the number and the spring through the quote route on this page before ordering anything.

Yes. This spring is safety critical and it sits in the front suspension, which needs proper equipment to take apart and put back together safely. We do not publish figures or a method for the job, so please do not work from a guide written for some other vehicle. Book it with a garage that handles suspension on this vehicle and have them read the number off the spring they remove and check it against OE 12657364-00 before the new one goes near the car.

Delivery takes 8 to 28 days from your order to your door. Read each one on its own when you are working out when the car can go in. If a garage slot is already booked, book it against the far end of the delivery time so the part is in your hands first. For a firmer date than that, ask through the quote route on this page before you order.

The material is metal with a black finish, so expect a dark finish rather than bare steel. That finish is cosmetic once the spring is on the car, because it sits underneath and out of sight, but it is worth handling carefully so the coating is not chipped before it goes on. Do not drag it across concrete when unpacking. If the finish on arrival looks different from the images on this page, raise it with us before the garage fits it.

It is an underbody part at the front of the car, a Front Coil Spring, so it is one of the front pair and not a rear item. No side is given for it, which means the same number covers the position on either side at the front. You will not see it without raising the vehicle. When you identify what you have, make sure the spring you took off came off the front, then match its number against the fitment table on this page before ordering.

The only tier listed is Original/Genuine, with BYD as the manufacturer, and the price shown on this page is for that part. Nothing is priced in the Aftermarket tier for this OE number, so there is no second choice to weigh up here. Where a second tier exists we put both on the page so you can see them side by side. If you would like us to look again for an alternative against this number, use the quote route and include a photograph of the old spring and its label with the request.
