OS Giken host
I’m planning on getting the OS Giken within this year but if possible, I’d like to have a separate diff so I can just swap the diffs with the one currently on my ‘18 tS
Does anyone have any experience with doing something similar ? Do I just look for Y58 4.3 differential or is it possible to just purchase the diff housing ? |

Get a separate whole assembly, swap the OS Giken in, then swap the whole assembly into your car and keep your original assembly as a backup, that's what I did.

For the carrier, just buy whatever you can find, the housing the is the same. I actually bought one from an automatic twin but I'm obviously only using it for the carrier itself. |

I would buy the whole diff assembly with a Torsen and ring and pinion inside, this way you do not have to tear apart your original diff and you can keep it on the side as a backup or if you ever sell the car it is a piece of cake to put the original diff back in.

If you get a complete pumpkin, then you can hot-swap the entire differential assembly.
Remember to stock up on axle seals, as they tear rather easily. OS Giken LSDs are backordered. PM me to order one and get in line for the next batch. |

You will go on ebay or to a local scrapyard and pick one up. Since you have a 2018 with the 4.3 final drive you want something like this so you can do what Code Money said below. Quote:
Oh and just as CSG said, they are backordered so if you're serious about this put in your order now. I put in my order in November with an ETA of March and it's been pushed back to July. |

@BackFlip may have a 4.3 diff assembly for cheaper than ebay, I bought my spare from him a few months ago.
