Used Peugeot 408 Subframe

The first-generation Peugeot 408 ran from 2010 to 2014 in markets where it was sold, and a second-generation 408 launched in 2023 as a completely different platform and bodystyle. These two generations share no subframe compatibility whatsoever, so always confirm which generation your car belongs to before approaching a breaker. Quoting your registration to the breaker is the safest way to make sure you get the right unit.

Both of those years sit within the first-generation 408 (2010–2014), so they are broadly the same platform and a subframe from that era is generally a strong candidate for fitment. That said, engine size can influence subframe specification, so confirm whether both vehicles carry the same engine as yours when you contact the breaker. Never assume fitment is guaranteed without the breaker checking the part against your registration.

Yes, engine size can affect subframe specification because heavier or more powerful drivetrains sometimes require a differently rated front subframe to handle the loads involved. When you contact a breaker, tell them the exact engine fitted to your 408, not just the model name, so they can match the correct unit. Confirming against your registration plate gives the breaker the best chance of supplying a directly compatible part.

Trim level alone — whether Active, Allure, or any other grade — does not determine subframe fitment; the subframe is part of the running gear, not the interior or cosmetic specification. What matters is the generation and engine size, not the badge on the back. You may find cosmetic or minor equipment differences between trim levels on the parts that surround the subframe, but the subframe itself is not trim-dependent.

No, the 2023 second-generation 408 is an entirely new vehicle on Stellantis's EMP2 platform and is not related to the original 408 built between 2010 and 2014. Subframes from the first-generation car will not be compatible with the second-generation model under any circumstances. Make sure any breaker you contact is sourcing a subframe from a 2023-onwards second-generation 408, confirmed against your registration.

A front subframe itself is a single central component and is not side-specific, but if you are also replacing front wishbones or related suspension arms at the same time, those parts are handed — nearside (NS, passenger side) and offside (OS, driver side) are not interchangeable. Always specify to the breaker exactly which components you need and whether any sided parts are included with the subframe. Confirming the full list of parts against your registration will help avoid ordering the wrong item.
