Blackline HLF021 BMW 168 Helical Gear LSD

• The LSD is a straight swap for the standard unit, you will only need to replace gaskets/seals and 2 diff bearings (if the originals cannot be re-used)
• Helical gear diffs do not require a special oil (OE diff oil is suitable)
• We recommend that the axle oil is changed after the first 500 miles as initially, they may create swarf - this is normal and will reduce with use
• This is a torque-biasing helical gear limited slip differential - not a plate type, viscous coupling or clutch pack differential (it does not lock)

• Includes assembled differential unit only. Bearings, gears, gaskets/seals etc are not included
