Diff Lab BMW 188mm Ring & Pinion 3.73 BMW 188mm Ring & Pinion 3.73

Crown and Pinion 3.73 to suit most early BMWs including E28, E30, E32, E34, E36 and M3 3.0L. These do not fit E46 or later.

Why not add an LSD while you're changing the gear ratio? It's a good time to install and LSD while you're there. If installing locally, you will also need a differential rebuild kit. If your LSD is worn beyond acceptable limits, you can also install an LSD rebuild kit.

We can rebuild your diff for you. We offer reasonable return postage rates via Couriers Please. Contact us for a fast quote.

Need help selecting the best ratio for your car. Look no further. Selecting the Right Ratio.

*Bearings may still be installed. These must be discarded. Gears are generally used unless specified otherwise. They are removed from working differentials. These must be installed either by me or by a professional and competent diff builder. See our Recommended Diff Builders page for more info.
