Diff Lab BMW E39 E46 323i 325i 328i 188K Diff Builder BMW E39 E46 323i 325i 328i 188K Diff Builder This is a fully rebuilt Limited Slip Differential for E39 or E46. It is a mid-case 188K unit which fits the E39 and E46 6-cylinder vehicles. A mid-sized 188K E39/E46 diff (same as supplied) in working condition must be provided upon exchange of your new differential. Return freight is available at a reasonable price.


Postage: Free delivery of your new diff to RX Automotive Brisbane and BMWreckers Brisbane. An additional money request will be sent via Paypal if the checkout under-prices the freight significantly for your address, as it will do for all regional areas.

Exchange Freight Option: Select this if you would like Diff Lab to organise the freight to return your old differential on your behalf. You will be Emailed a courier label to stick onto the parcel and told which day to leave it out for courier collection. Select 'not applicable' if you are going to organise your own fright to return your old differential.

See why this is the best choice for you and your BMW:

  1. Built in Brisbane by one of the most experienced BMW diff builders in Australia.
  2. Fully blueprinted to target specifications, not to any old specs within a wide range.
  3. All OEM parts used from the Diff Lab 188K rebuild kit that contains many extra components that other diff shops do not bother to use.
  4. New clutches and steels installed as required.
  5. Have any ratio you like - even the rare ones.
  6. Delivered to your door and ready to bolt in. Just add LSD oil.
  7. Exchange service with fast change-over. Usually assembled within 1-2 days.
  8. Our LSDs are inspected carefully with parts replaced as required.
  9. Never has an LSD been returned to me under warranty. I often repair other shops' work when it goes bad for the customer.
  10. Should you need support, you are in good hands and I will get you back on the road ASAP.
I often rebuild already rebuilt LSDs. There is only one way to rebuild an LSD and that is the correct way. My diffs are built to work and last. They will not need to be opened for many years of road driving. Just change the oil with good quality a quality synthetic product as needed.
