Rear Lower Control Arm for BYD Sealion 05 DM-i, OE 12740251-00

This arm fits a large number of vehicles, so treat the model name as a starting point only. Work through the fitment table on this page against your own variant and build year, then check the OE number 12740251-00 or the alternative reference marked on the arm currently on the car. Rear suspension arms differ between builds in ways that are hard to judge by eye. If the table does not clearly cover your vehicle, send a photograph of the old part and its label through the quote route on this page and we will confirm it against the OE number.

This arm is offered in two tiers, both priced on this page. The Original/Genuine tier is the BYD part, the version the vehicle was built with. The Aftermarket tier is made by another manufacturer to suit the same application under OE 12740251-00. Both are supplied new and both are shown in the fitment table on this page. What separates them is who made the part and what it costs. Decide which tier you want at the point of ordering, and tell the fitting garage which one to expect.

It is. That stamp and OE 12740251-00 are two references for the same rear lower arm, and the SC2E form is the one you are most likely to find on the component. Rear arms carry their marking on a flat face that gathers road grime, so clean it lightly before deciding it does not match ours. If the number you uncover is different again, send a photograph of the old part and its label through the quote route on this page and we will check it against the fitment table.

Yes. This arm is flagged as safety critical, and it is the part of the rear suspension that locates the wheel. Work of that kind belongs in a workshop with a ramp and the right equipment, and with somebody who can check the car over once it is back on the ground. We do not supply torque figures or a fitting procedure with the part, so your technician should work to the vehicle manufacturer's own data. Give them OE 12740251-00 before the old arm is released.

Delivery takes 8 to 28 days from your order to your door. If the car is already on a ramp waiting, contact us through this page before ordering so we can tell you the position on the day. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12740251-00.

This part is metal, and weight details are shown on this page. Metal means the arm cannot be eased into a position it was not made for, so the mounting points have to line up exactly with the car. When it arrives, hold it against the arm you removed and compare the eye positions and the joint angle, then check the fitment table on this page. If anything differs, come back to us before it goes on.

It is an underbody part at the rear of the vehicle, in the lower position of the rear suspension, and no left or right side is given for it. Reaching it means getting the car up rather than working from above. Because no side is specified, check the images and the fitment table on this page against your own car before ordering. If your vehicle uses a handed pair at that location, send a photograph of the old part and its label through the quote route on this page so we can confirm what you need.
