Second Hand Peugeot 408 Seat Belt

The Peugeot 408 in the UK market runs from 2022 onwards as a second-generation model, a crossover coupé that is distinct from the original first-generation 408 saloon sold in some markets but not widely in the UK. When searching for a seat belt, make sure you and the breaker are both clear on which generation you have, as the two are completely different cars with no shared interior parts. Always quote your registration to the breaker so they can confirm the exact generation.

Both the 2022 and 2023 408 sit within the same second-generation model range, so a seat belt from either year is likely to be compatible provided the trim level and seating position match. That said, always confirm with the breaker against your registration, as minor mid-year running changes can occasionally affect pretensioner variants. Because 408 seat belts are pretensioner units, professional fitting is strongly recommended for safety.

Trim level can matter for the 408 because seat specification and upholstery vary across Active, Allure, GT, and GT Premium grades, which may affect the belt stalk, buckle style, or integrated components. Where belts are mechanically interchangeable across trims, you may still notice small cosmetic differences such as stitching colour or buckle finish, so it is worth mentioning your trim to the breaker. Confirm the specific trim fitment with the breaker against your registration before purchasing.

Yes, seat belts are side-specific — the nearside (NS) is the passenger side and the offside (OS) is the driver side — and the two are not interchangeable. Always specify clearly to the breaker which side you need, along with the row (front or rear) and your seat position, to avoid receiving the wrong unit. Getting this right is especially important as pretensioner seat belts are safety-critical and single-use after any deployment.

Peugeot 408 seat belts include pyrotechnic pretensioners, which means they are safety-critical components that Findapart and breakers strongly recommend having fitted by a qualified technician. Pretensioner belts are single-use — if the one you are buying was deployed in an accident it cannot be reused, so confirm with the breaker that the belt has never been triggered. A professional fitter will also ensure the anchorage points and SRS system connections are correctly reinstated.

The 408 is a unique crossover coupé body style and its interior dimensions and mounting points are specific to that model, so seat belts from other Peugeot models such as the 308 or 3008 are very unlikely to be a direct fit. Some shared platform components exist across the Stellantis group, but whether any particular belt crosses over correctly is not something that can be confirmed without checking your registration details against the donor vehicle. Route this question to the breaker, who can compare part numbers before you commit to buying.
