TECH 53 - Nissan 370Z / G37 Weld-On Kit for Quickchange Differential

Winters Quickchange differentials are highly sought after in the drifting world, particularly for competition-ready cars where rapid gear changes and reliability are crucial. Unfortunately they're not a bolt-on upgrade on any car out there. 

We designed this kit to ease the installation process of your new differential. You won't have to fabricate any additional components. The only fabrication work required is cutting the subframe and welding our plates on it. This kit is engineered to ensure precise alignment of the differential with the driveshaft and axles.

You can even use 2 « short » 370Z axles and our OEM axle adapters (available soon).

Does this fit my car?

This kit will fit a 10" ring gear Winters Quickchange differential on a Nissan 370Z or Infinity G37 steel rear subframe. 

What's included?

We provide all the necessary steel plates to install your new differential on your subframe. We also include the hardware you need to fix our plates on the casing.

Notes

In order to fit our plates on the front flange, you will use the bolts that were already threaded on the flange.
