Z1 Street Pro Nissan Z Limited Slip Differential was produced exclusively for manual transmission models to provide an increase in acceleration performance, cornering stability, and predictability when driving the car at the limit.
WHY DO YOU NEED IT?
The factory differential in manual transmission Sport trim Z's is a standard open differential. The biggest flaw with open differentials is their inability to distribute power between both wheels. With an open differential, torque is applied equally between both wheels, however in situations where wheel slip occurs (such as rapid acceleration) the slipping wheel will receive almost all torque. This imbalance between the left and right wheel leads to poor cornering stability and poor straight-line acceleration, infamously known as the "one-wheel peel". This is a concerning problem on cars with higher levels of power and considering the Z starts life at 400hp, we think this is a problem that should be addressed early in ownership.
The SP is a helical differential that is a dramatic improvement over open differentials given its considerably greater ability to distribute torque at both wheels. With its internal gear design, it boasts exemplary street manners and is operationally quiet when compared to aftermarket clutch-type differentials that tend to chatter or clunk when cornering at low speeds because of axle bind. The Z1 SP differential is a helical unit that exhibits no axle binding and provides smooth operation under any circumstances. Because of the internal construction, the Z1 SP is low maintenance (only regular fluid service intervals) and ensures an exceptional life span with no special fluids or friction modifiers needed. Standard fluids may be used, however, Z1 recommends the use of Red Line or Motul differential fluid.
Installation Note
It is VERY IMPORTANT that this installation is done by a competent and experienced driveline shop. Incorrect gear pattern, out-of-spec back-lash or pre-load will result in accelerated wear, noise, etc.
If you choose to locate a driveline shop for installation, we recommend purchasing new side bearings and side axle seals. As a convenience, this has been included as an option below. (Different spec side shims may be needed for installation - available separately HERE).
