Frequently Asked Questions: OE 13701850-00
How do I know this is the left rear rail and not the right one?
This listing is for the left rear rail, fitted at the rear of the underbody. Before you order, look at the position of the old rail on the car and compare it with where this one sits, along with its fixings, so you can be sure the side matches before you commit to the price shown on this page. The OE number on the old part is the surest way to confirm it lines up with 13701850-00.
How do I know this rear rail will fit my BYD Seal 05 DM-i?
Before you order, take the old rail off or look underneath and find its OE number, 13701850-00, stamped or printed on the part. Match that number against the one listed here rather than going on the model name alone, since rails can differ between build runs. If the number on your car matches, you can order with confidence. If you cannot find or read the number, or it does not match, hold off and check further before buying, so you are not left with a rail that does not sit right on your underbody.
The number on my old rail is different, what do I do?
If the number on your old part does not match the OE number 13701850-00, do not order against a guess. Use the quote route on this page and enter the number you can read stamped on your old part, along with your vehicle details. That lets someone check it against this listing before you buy, rather than you deciding from two numbers alone. A rail like this is fixed structurally to the underbody, so confirming the match first is a better step than ordering and finding out afterwards that it does not line up.
How will a rail this size actually be delivered to me?
It travels as one boxed length, and the packaging details are shown on this page. Delivery time is confirmed with your quote. Before it arrives, get the model and the model year exactly as shown on your registration document, ready to set against this listing and the OE number 13701850-00 on the old rail. The shipping cost is confirmed with your quote.
What material is this rail made of?
Metal is what this rail is made from. Before you order, find the number stamped on the part you are taking off the car and read it directly from the metal itself. Compare it against the OE number 13701850-00 rather than relying on a listing title or a diagram. Doing this confirms you have the same rail fitted to the same side and the same position as the one currently on the car. A structural underbody part like this one is worth checking properly before you commit to an order.
