South Side Performance is offering, another first for the R35 GTR, our SSP RS rear drive shaft kit. This component is another in a line of SSP products that strengthens and supports high horsepower GTR‘s.

In months of testing R35’s running very aggressive power combinations, SSP has thought a few steps ahead and engineered a few of the pieces that will be needed once your GTR starts pushing big power. SSP has experience with high horsepower AWD cars and knows that the axle shafts are going to be a point of weakness once certain power levels are exceeded. So, instead of responding to failures after they happen, SSP has designed a solution to prevent the failure from happening in the first place.

Specifications:
This axle kit was specifically designed for the new GTR, starting with a new larger 6-ball outer and inner CV joints. The unique thing about this is that most newer cars are coming with outer/inner CV.'s with 8 balls internally instead of 6 like the traditionally designed axles that most of us have relied upon in the past.

While there are many advantages to this 8 ball design, it is a real disadvantage in a high performance application. In order to fit 8 balls into the CV, material is taken away from the cage (internal part of the CV that keeps the ball bearings in place). The solid area in between the cage windows (the spot where the ball goes into the CV housing) is reduced for the extra 2 balls to fit. The result of this loss of material is a weak spot in the axle itself and it is at these spots (between the cage windows )that 99% of cage failures stem from.

By finding the point of weakness on the stock shafts, it became clear that going back to a 6 ball design would be the best solution to the problem. Our 6-ball design is not only larger in diameter, but this design keeps sufficient material where it is needed to withstand high HP. But, the improvements do not end there, as our system also includes chromoly "uninterrupted torque-line center bars". This innovation from DSS allows the axle center bar to become tensional (allowed to twist) without any unnecessary snap ring grooves, boot location grooves, or other deviations in the axle bar that would cause concentrated stress points and eventual failure to the bar. The inner CV has been replaced with the famous Porsche 930 design cross-groove CV and we have also included a conversion plate and hardware to mount the CV to the OE differential flanges.

The result of combining all of these new design elements is one serious axle set for the street, drag, or rally applications. And the innovation does not end there as SSP will also be bringing upgraded front axles and an upgraded front drive shaft solution to market for this incredible car over the next few weeks. As always, these heavy duty upgrades are available only from the guys at South Side Performance Drive Shaft Shop.
