 Product Description

Current lead time is 4 Weeks from time of order. 


Differentials are the heart of every axle. It needs to perform the way you need, every time. If your differential doesn’t work, then the rest of your axle doesn’t work. You can have the best built axles available. But if your differential doesn’t work because of a poor set up or inferior components, then your other axle upgrades don’t work either.


Our Toyota 8” 4Cyl. differentials are designed with the best parts, Including Timkin and Koyo bearings, as well as Yukon seals, shims, and hardware. Our pinions have an enlarged shaft for strength, and a larger triple drilled pinion flange. They are set up by professionals, to give you the best performance possible.


Each differential comes professionally set-up and includes:

- New Koyo or Timkin bearings
- Yukon seals, shims, and small parts
- New Yukon Gear and Axle Ring and Pinion
- Brand new Yukon Differential Housing
- Larger Pinion shaft than stock
- Solid pinion spacer
- Yukon Triple drilled flange
- No core required

  1. Great product/service

    Posted by Ricky on Feb 13th 2018

    I ordered a 4.10 3rd with a Grizzly locker and it arrived about a week later (due to needing to the uncommon request of 4.10’s) I received my order and it was in great condition. I also called Coreswest and spoke to the person who builds the gear sets, he was very knowledgeable about the questions I had. I will definitely order from here again when I replace my front 3rd.

  3. Best deal around

    Posted by Stephen on Sep 18th 2017

    After a month or 2 of shopping around I decided on purchasing from here. Free shipping and in only 5 days,no one can do it faster for the price and quality. I went with the grizzly locker and 4.88 after knowing that 5.29s just don't last. Super happy with the product and will be ordering another for the rear.
