Front Lower Control Arm (Left) for BYD Song PLUS, OE 12689147-00

This is the left hand front lower arm. Sides are called from the driver's seat looking forward, not from standing in front of the car, so left here is the nearside as the car sits in the road. Look under the front of the car on that side and compare the shape against the photographs on this page, because the opposite side arm will not bolt up. The OE number 12689147-00 belongs to this side only. If you cannot tell which one you have off the car, send a photograph through the quote route before ordering.

This arm covers a spread of BYD models, so the Song PLUS in the title is the headline application rather than the whole story. Work through the fitment table on this page and match your own model year and variant, which you can read from your registration document. If your car appears there, this is the arm for it. If your exact variant is not shown, read the OE number off the old arm and send a photograph of it and its label through the quote route, and we will confirm it against the OE number before anything is ordered.

Two versions of this arm are offered and both are priced on this page. The Original/Genuine version is the BYD item. The Aftermarket version comes from an independent supplier and matches the same OE number and the same fitment data. Beyond the maker and the price, the application details are the same for each, so the choice comes down to budget and preference rather than to fitment. If you want the BYD item specifically, select the Original/Genuine tier before you add it to your basket.

This arm also carries the reference SA3F-2904010A. If the number on your old arm reads that way rather than 12689147-00, you are looking at the same item under a second reference and you are on the correct listing. Suspension castings are often stamped by the supplier rather than by the vehicle manufacturer, so clean the surface and read every character including any suffix. Where what you have matches neither reference shown here, send the characters you can make out through the quote route and we will look it up rather than guess.

Yes. This arm is safety critical, so it is not a job to improvise on a driveway. Have it fitted by a qualified technician who can support the car properly and work to the manufacturer's figures. We do not publish those figures here and nothing should be assumed from the listing. It mounts underbody, which means lifting equipment and a proper working space are needed. Give your garage the OE number 12689147-00 and point them at the fitment table on this page so they can confirm the item before the car is booked in.

The delivery time is 8 to 28 days, from order to door. Read the two together. If you need it faster than that, ask through the quote route before ordering and we will tell you what is actually possible on this line. 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 12689147-00.

This arm is metal, and nothing further about the alloy or any coating is given beyond that. Take that as the family of material and no more. What it does tell you is that the item is rigid, so it wants handling that keeps the mounting faces true on the bench. If you need a fuller material statement for a fleet or insurance record, ask through the quote route.
