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. We stock the Hyperlock to suit. 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.
