FAQ's

Will this fit my car?
We can only confirm fitment for the vehicles listed above under "vehicle compatibility". If your car is not listed there, then we don't know if it will fit.

Do you make these to suit other cars?
We only sell the part listed on our website. If it's not listed on our website, then we don't sell it. Sorry.

What's the advantage of using the GKTech 350/370z diff conversion bushes?
The 350z/370z/G35/G37 diffs are becoming more readily available and are newer then the 15+ year old diffs people use now. They also have driveshaft sensors which is great to use for calculating wheel speed. The stub spline that goes into the diff center is the same as R33 GTR being 31 spline. As oppose to the R32 GTR diff being 30 spine and the R33 GTS-T diff being 29 spline.

The pinion gear thread is also larger on these diffs then any S/R chassis diff. They also use Rzeppa style driveshafts, which are significantly stronger as oppose to the Tripod design S/R chassis have which are weaker.

They driveshafts also directly bolt up to S/R chassis wheel hubs.

What modifications are required, is this hard to fit?
You will need to redrill you diff flange to suit your tailshaft bolt PCD, which can be done relivetly easily. Then press the bushes into the diff and subframe. Please take note of which direction the rear bush is to be facing based on the postion of the diff stud before pressing the bush in.

Is there anything else needed for installation?
You will need to purchase the diff itself, apart from that the OEM hardware can be used as the bushes will arrive as shown in the product photo.

Can I install this myself? If so how long will installation take?
Yes, it is relatively straight forward, once the subframe is out it should take around 45 minutes.

Do these bushes offset where the diff mounts in the subframe?
No, the bushings have been designed to align the diff in the center of the subframe.

I keep breaking the teeth off my crown wheel, will this diff be strong enough to stop that happening?
No, in fact the crown wheel and pinion and the same between S/R/350z/370z/G35/G37. That is why they are still called an R200.

What sort of ratios do these diffs have?
The 350z/370z/G35/G37 diffs have a wide variety of OEM ratios which can be seen here;
Z33 - MT - R200 - 3.538
