The GKTECH S/R Chassis to 350Z/370Z Diff conversion bushings allow you to bolt in the stronger 350/370Z/G35/G37 differential to your 2 bolt R200 S14/S15/R33/R34 subframe.

The bushings are CNC Machined from 6061-T6 aluminium and require no further modification to the subframe, just simply press the two bushings 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 bushings and two rear bushings.
