Rear Coil Spring for BYD Yuan Pro, OE 12843228-00

This spring carries two references, the OE number 12843228-00 and SCEG-2911111. Which of them appears on a marking or on a supplier document depends entirely on who wrote it, and neither is more correct than the other. Read whatever you can from your old spring or your paperwork and compare it with both. A match on either puts you on the right listing. A match on neither is worth a question, so send the number with a photograph of the old part and its label through the quote route before ordering.

Yes. This spring is safety critical. It sits underneath the car, at the rear, so reaching it means taking the rear suspension apart, and that belongs on a lift with the proper equipment rather than on a drive. Have a qualified technician carry out the work and inspect the opposite corner while the car is already up. Order the spring first and have it checked against the old one before any booking is confirmed, so the car is not stranded mid job.

Delivery takes 8 to 25 days from your order to your door. A car with a rear spring out is going nowhere, so have the part on site and unpacked before the workshop lifts it. If the dates look awkward against a booking you have already made, ask us through the quote route first. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.

This spring is made of metal, as you would expect of a coil spring rather than a cushioning component. Take it out of the box and stand it beside the old spring before anything is fitted, checking the coil count and the overall height by eye. If they differ, stop and use the quote route on this page rather than fitting it and hoping it is close enough for the car.

This spring sits underneath the car, at the rear, within the spring and top mount group. That means access from below with the rear suspension unloaded, and no work inside the cabin or under the bonnet. No left or right side applies to this one, so the same item serves either rear corner and there is no handed version to pick. Springs are usually changed in pairs, so look at the fitment table on this page and decide whether you want two before you order.

Because only one is offered. BYD is held as the manufacturer of the Original/Genuine item, the aftermarket manufacturer against OE number 12843228-00 is empty, and so the page carries a single tier with the price for the genuine spring. That reflects what we can currently source, nothing more. If you would like us to look for an equivalent under the alternative reference SCEG-2911111, use the quote route with a photograph of the old part and its label and we will tell you what is available.
