Helical Gear LSD BMW 188K differential

188K Medium Case 10 Bolt Crown Wheel LSD for ratio 3.15>

This is a Torque Biasing Helical Gear LSD. These are generally regarded as a nicer road LSD as they have little side effects during normal driving (unlike plate type LSD's that constantly resist differing wheels speeds during cornering) They do not require a special oil. We recommend that the axle oil is changed after the first 500 miles as initially they can create swarf - this is normal and will reduce with use.
