Rear Suspension Control Arm for BYD Sealion 05 DM-i, OE 12740272-00

This arm fits a wide spread of BYD models rather than one, so the name of your car on its own is not enough to confirm it. Work from the fitment table on this page and match your model and model year, then the variant, exactly as they are written there. If your car sits close to a listed entry without being it, do not order on the resemblance. Read the reference marked on the arm you are removing and compare it with the OE number 12740272-00, or send it to us through the quote route on this page.

Two tiers are offered for this arm and both are priced on this page. The Original/Genuine version is the BYD part, made to the vehicle manufacturer's own specification and carrying its reference. The Aftermarket version is an equivalent supplied by an independent manufacturer for the same application. That manufacturer is not named here, so if the source matters to your workshop, ask through the quote route on this page before ordering. Both are listed in New condition and both are tied to the same fitment table on this page, so the choice between them is yours to make.

No, that is the same item. This arm carries the OE number 12740272-00 and is also known as SC2E-2914080, and either reference points at the part you are reading about. The second style tends to be the one you actually find on a part that has been on the car, so read the whole string rather than the first few characters before you decide. If what you have matches neither, note it down with your BYD Sealion 05 DM-i details and send it through the quote route on this page so we can check the fitment table against it.

Yes. This rear control arm is safety critical, so it belongs to the group where a fitting error changes how the car behaves on the road rather than how it looks. The car has to be properly supported for the work, and the geometry needs setting again once the new arm is on. That points at a workshop with alignment equipment. We publish no torque settings or fitting sequence here, because those come from the vehicle manufacturer. Order against 12740272-00 and let a qualified technician handle the rest of it.

Allow 8 to 25 days for delivery, counted from your order to your door. Packaging details for this arm are shown on this page. If the timing will not suit your garage, ask through the quote route on this page before you order. The shipping cost for your country is shown at checkout before you pay. Before you order, check the number on your old part against OE 12740272-00.

The material for this arm is Metal. It is a load bearing suspension part rather than a cover or a trim piece. Metal also means the reference is usually marked into the body of the arm, so the one coming off the car can be read and checked before the new part is ordered. If your workshop wants a written specification for the job, request it through the quote route on this page rather than working from an assumed figure.

It mounts underbody at the rear of the car, so access is from below with the car raised and the wheel area clear. Nothing about this job is done from inside the boot or the cabin. Expect road dirt on the old arm and on its fixings, which is worth cleaning off before you try to read the reference marked there. Match what you find against the OE number 12740272-00 shown on this page, then confirm your car in the fitment table on this page before the new arm is ordered.
