Description
Right Front Seat Belt, Pyrotechnic Seat Belt, Passenger Belt for PEUGEOT 407. Color FXX Black.
This right front pyrotechnic seat belt is designed for the Peugeot 407 and supplies reliable occupant restraint with an integrated pretensioner for crash events. Ideal for professional workshops and experienced DIY mechanics, the belt is often searched and identified by part numbers 96439574XX and 8974HH. The assembly replaces the passenger-side front belt and matches the factory color code FXX (Black).
The unit restores original safety functions: webbing restraint, automatic retraction, and pyrotechnic pretensioner activation during a collision. Because this is a safety-critical component, fitment by an experienced technician is recommended. Technically minded customers will appreciate that the retractor contains the spring-loaded spool, inertia locking mechanism and the pyrotechnic pretensioner module which acts to remove excess slack instantly when triggered.

Installation Recommendations
Always follow proper safety procedures when replacing any SRS component. Before starting, disconnect the negative battery terminal and wait at least 10 minutes to allow the supplemental restraint system capacitors to discharge. Remove interior trim panels to access the retractor and lower anchor bolts. Unbolt the belt assembly from its mounting points, carefully disconnect any electrical connector for the pretensioner, and install the replacement in the reverse order. Ensure connectors are fully engaged and routing of the webbing is correct. Tighten mounting bolts to the manufacturer’s torque specifications and verify correct operation: belt retracts freely, locks under sudden pull, and no SRS warning lamp remains on.
Why This Part Commonly Fails
- Pretensioner Deployment: The pyrotechnic pretensioner is designed to deploy in a crash and is single-use; once deployed it must be replaced.
- Wear And Tear: Webbing can fray, stain, or lose flexibility over years of use, reducing effectiveness.
- Retractor Problems: The locking mechanism or spring can seize from contamination or internal fatigue, causing poor retraction or locking failure.
- Corrosion And Fastener Damage: Moisture and road salt may corrode anchors and bolts, complicating removal and compromising mount integrity.
This part is commonly sought under its part numbers—entering 96439574XX or 8974HH will typically find this exact assembly. For safe and correct replacement, use suitable tools, follow manufacturer procedures, and if in doubt, have the unit fitted and checked by a qualified technician with appropriate diagnostic equipment to confirm the SRS system status after installation.
