SELECTED OPTIONS
Which rear
housing do you have?
Z33/ Z34
Single bolt diff housing (three bushes in total)
The GKTECH S/R Chassis
to 350z/370z Diff conversion bushes allow you to bolt in the stronger
350z/370z/G35/G37 differential to your 2 bolt R200 S14/S15/R33/R34 subframe.
The bushes are CNC
Machined from 6061-T6 aluminium and require no further modification to the
subframe, just simply press the two bushes into the diff, while pressing the
other in the subframe.
You will notice there
are two options to choose from, most commonly people have the single bolt
cover, which comes as shown in the product photo.
The other selection is
for two bolt Z33/Z34 diff housings, which will come with two front bushes and
two rear bushes.

please check driveshaft (CV/axle) length to ensure there are no possibilities
of the driveshaft (CV/axle) overextending or driveshaft (CV/axle) compression,
which may lead to failures.
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 parts
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 than the 15+ year old
diffs people use now. They also have driveshaft (CV/ axle) sensors which are
great to use for calculating wheel speed. The stub spline that goes into the
diff center is the same as R33 GTR being a 31 spline. As opposed to the R32 GTR
diff being 30 spline 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 (CV/ axles), which are significantly stronger as oppose to
the Tripod design S/R chassis have which are weaker.
The driveshafts of the
all the CV/ axles excluding the 370z also directly bolt up to S/R chassis wheel
hubs. The 370z shafts have a GTR spline output to the rear wheel bearing/hub,
meaning the wheel bearing/hub would need to be changed to the GTR equivalent.
What modifications are
required, is this hard to fit?
You will need to redrill
your diff flange to suit your tailshaft bolt PCD, which can be done relatively
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 position 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
straightforward. 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, 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
Z33 - MT - R200V - 3.538
Z33 - AT - R200V - 3.357
