Genuine BMW LSD for BMW M135i/M235i/M140i/M240i. Manual and Auto options please select which one you need.
These LSD's provide a huge improvement to rear-end traction on these cars. We have one of these on our M140i and it completely transforms the car. Another benefit is these are full units, not inserts so you can keep your standard Diff and swap them out before you sell the car. They are a direct swap with the standard differential so no need to exchange your old diff or carry out any irreversible machining work.
This LSD will use 75w140 gear oil, unlike the standard open diff.
