Usukani has introduced an aluminum rear shaft drive conversion system for the Sakura D4. This shaft system is compatible with the original 3 Racing Sakura D4 kit and Usukani D4 carbon conversion kit (RWD application only). This provides you the ability to change the belt drive system to a shaft and gear drive-train configuration.
We had a chance to try out the new shaft drive system and was glad to install it on a completely stock Sakura D4 RWD chassis. Check out the full install in our short time lapse video below.
The installation of the shaft drive system was very straight forward and it helps to have built the chassis to begin with. The conversion kit requires some of the original D4 parts, but a vast majority are removed including many of the original screws and aluminum stiffeners. The overall quality of the aluminum and finish is high and we couldn’t find any burrs or blemishes. The instructions were very helpful with the installation of the kit. The switch to shaft drive from belt came with the usual increase in overall decibels of the running chassis, but Usukani have done a great job in making it a negligible difference. As a lot of the products we review on DriftMission don’t include any instructions, so it was nice to see helpful instructions included with the kit.
If you are not a fan of the gear drive-train, the conversion kit is also compatible as a belt drive system. The conversion kit makes it possible to switch between belt and gear drive-trains, it is not restricted to the gear drive only.

The aluminum parts are made of a high quality aluminum alloy and milled to a very high level of detail and quality. Assembly was made easy as all the parts are very precise which makes assembly and fitment quick and easy. Everything fastens very well together and the gears mesh very well together.
This kit replaces the entire rear bulkhead and motor mount of the chassis with a one piece aluminum bulkhead design.

It is only made for D4 RWD chassis, and overall this is an excellent upgrade for any 3Racing D4 owner.
This kit retails for approximately $80USD and is very generously equipped for that price.

Overall the value of this upgrade is fantastic and will leave you with a more fun to drift 3Racing Sakura D4.

Usukani is new to the scene but we are sure they are here to stay given the quality and design of their products. Converting the D4 to shaft drive was a very nice enhancement as you can see in our video below. The chassis became much more responsive and allows for more precise control of your throttle. After running the D4 with this Usukani Shaft Drive Kit, I can’t imagine going back! Overall we would recommend this kit to anyone looking to enhance the performance of the 3Racing Sakura D4.
