Rear Torsion Beam Mounting Bracket (Left) for BYD Seal 05, OE 12377277-00

This is the left-hand rear torsion beam mounting bracket. Left and right are named from the driver's seat looking forward, so on a right-hand drive car this is the passenger side, at the rear under the floor. The opposite hand is sold separately and carries a different OE number, which is why ordering from a photograph alone tends to go wrong. Put the car up, look at the bracket you are taking off, and match the marking on it against 12377277-00 shown here before you commit to the order.

Possibly, and the fitment table on this page is where to settle it. This bracket suits a range of BYD models, so year and variant do more work than the model name in deciding whether it suits your car. Find your exact build in that table before ordering. Where your car does not appear, or the entry looks unclear to you, send a photograph of the old bracket and its label along with OE 12377277-00 through the quote route and we will check it before you spend anything.

Yes. One component often carries more than one reference because the vehicle maker's catalogue and the supply catalogue number things differently. Read every marking on the part you removed, including anything on the hidden face, and compare them with both references printed on this page. If you hold a number that matches neither, pass it to us through the quote route with the vehicle details instead of judging the match from the shape.

This bracket is marked safety critical, so the honest answer is that it belongs with someone equipped for suspension work. It is a rear underbody fixing and the car has to be raised and supported before anything comes apart. Tightening figures and any setting up afterwards are the vehicle maker's, not ours, and we do not publish them here. Hand the job to a garage with a ramp and the correct data for the Seal 05, and ask them to check the rear of the car once the new bracket is in place.

Allow 8 to 25 days for delivery, counted from your order to your door. If the car is in daily use, get the order placed first and hold the garage booking until the bracket is actually with you and has been checked. 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 12377277-00.

Metal, in the black finish shown here. It is an underbody fixing, so expect to be working on it with the car raised and the surrounding area cleaned back first. The black finish is what it arrives in and no further preparation is described. Before it goes on, wipe the mating faces so nothing is trapped behind the new bracket. Anything beyond the material and the colour is not covered here, so treat the images and the fitment table on this page as your reference.

Not on this page. Only the Original/Genuine BYD bracket is sourced against OE 12377277-00, so there is a single version listed instead of an Original/Genuine and Aftermarket pair. Some listings in the catalogue carry both, and this one does not, purely because no Aftermarket equivalent has been taken on for the reference. The price shown on this page therefore belongs to that one version. If you want us to look at whether an equivalent exists, send the OE number and your vehicle details through the quote route.
