BMW Welded Diff Conversion Kits

‘BMW Welded Diff Conversion Service’ is for customers who want to send us their original open or LSD differential and ring gear only and have us carry out the separation of the factory welded ring gear and differential. We take your supplied welded diff and ring gear, split them and then machine the ring gear to spec, drill and thread the ring gear to accept bolts. After this is complete, you will need to install this into your existing axle, this is a service we can provide at an additional cost.
