BMW E60 M5, E90 E92 M3 LSD Exchange Diff - DiffLab

BMW E60 M5, E90 E92 M3 LSD Diff Upgrade Service

Diff Lab

  • $2,999

Exchange differential to suit E60 M5 and E90/E92 M3. Rear aluminium cover not included (keep your own). There are options to select a ring and pinion upgrade, an LSD upgrade, or both. Ring and pinion upgrades to 3.91, 4.10, 4.45 and 4.75 necessitate a complete strip and rebuild. LSD upgrades will not involve changing any pinion components (only carrier bearings and side seals are changed). 

The LSD upgrade will resolve the "M clunk" issues which affect the factory fitted LSD. It is essential to check the driveshafts for wear also, as the factory fitted LSD can wear these prematurely. Noise may remain if the driveshafts are worn and are not replaced.

This exchange differential can be delivered to a partner workshop for a same-day change-over. Diff Lab's partner workshop will drain, clean and return the old differential on your behalf. There is no core deposit paid when using a partner workshop. Some partner workshops have free delivery, or discounted postage.


Postage Options

Postage: Free delivery of your new diff to RX Automotive Brisbane and Brisbane Motor Works. 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.

Diff Lab often rebuilds already rebuilt LSDs. There is only one way to rebuild an LSD and that is the correct way. Too often Diff Lab opens rebuilt LSDs to find internals installed backwards, upside-down, worn beyond manufacturer limits, and non-OEM parts used. I often find strange looking shims in places where they don't belong. I find a lot of metal shavings, deformed parts, bolts without thread locker, incorrect or undersize bolts installed, strange modified LSDs which self-destruct and assembly specs way outside of the manufacturer's guidelines. These unlucky customers have to pay for two rebuilds: the dodgy work, and then Diff Lab's rebuild. Don't get caught out. Diff Lab 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. You wouldn't hire a clown to fix a leak in the john, so don't hire one to work on your differential either. Choose Diff Lab instead.
