MAKING GS400 REAR END SWAPS EASIER
When we were asked by one of our customers to develop a mount swap kit for the GS400 rear diff, we started from a fresh slate. We looked at the process, the challenges and ultimately how we would want to install a kit. The result is this relay bracket that is self-locating so you know where to modify the subframe and is stout and straight forward when it comes to actually mount the new diff, thanks to ample landing pads for the pinion and pre-threaded holes.
GS400 Rear End Benefits:
-GS400 rear ends are readily available and bulletproof providing a great upgrade for cars adding big power. Both the 1KS IS we are rebuilding and the Zen Motors GTA time attack car use this rear end.
-Better ratio for 6-spds. The tall ratio of a factory IS auto or manual does not allow for full advantage from the 6spd gearbox. When swapping a V160.161 or a CD009, the GS400 rear diff makes for a better final drive.
-1/4" thick steel plate, designed, bent and fabricated in the USA.
-Pre threaded pinion plate mounts that utilize the same bushings as stock minus the top cushions between the diff and subframe.
-Also includes our weld-in adapter plates to use the GS rear cover
-Subframe modification required, but if the plate fits flush, you are good to go. Final weldment required for proper support.
If you have any questions please let us know.
Axles from these cars should work:
This component is part of our IS300 rear Diff swap kit which adds a Guibo delete plate that allows and easy custom driveshaft build and the lowest weight and best support on the market.
