Condition, Application, and Benefits of Installation

This item comes from the group of used seat belts and parts, allowing for an economical repair of the safety system while maintaining original manufacturer specifications. This choice is particularly beneficial when a belt needs replacement after a collision, pretensioner activation, or due to wear and tear.

Replacing the rear left belt in a Mercedes W211 is important for:

• Restoring full functionality of the safety system for rear seat passengers.
• Maintaining compatibility with factory mounting points and webbing routing.
• Ensuring predictable vehicle behavior during sudden braking or impact.

Why Choose an Original Mercedes Seat Belt

An original Mercedes W211 seat belt ensures factory fitment with the vehicle's body structure and compatibility with other system components, such as pretensioners and seat mounts. Unlike universal solutions, a component from the same product line guarantees correct webbing routing geometry and appropriate retractor mechanism performance characteristics.
