Detailed Description

Suspensia X05LA0380 is a suspension control arm engineered for BMW rear suspension service where the rear right lower rearward arm is worn, bent, or no longer holding alignment. It is built from steel and supplied with bushings installed, using a regular-grade design with black bushings and no grease fitting, ball joint, or pre-greased assembly. This makes it a direct replacement for the original-style arm on applications such as BMW 530i, 540i, 740i, and M550i xDrive. The part number X05LA0380 also cross-references Delphi TC4618 for the same application.

Suspensia manufactures chassis components in an automated OE production environment and states its facility is certified to IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and ISO 50001:2018 standards. That manufacturing focus supports consistent fit and repeatable part quality for BMW suspension repair.

Installation Notes

Verify the rear right lower rearward position before installation and compare the original arm length, bushing orientation, and mounting points to the new part. Because this arm is not pre-greased and does not include a ball joint, grease fitting, cotter pin, castle nut, or lock nut, reuse or source any required fasteners separately as needed for the vehicle. An alignment check is recommended after suspension component replacement.
