KAAZ LSD Limited Slip Differential 3S AWD REAR Diff 3000GT Stealth

KAAZ LSD - Limited Slip Differential
3000GT/Stealth AWD - ** REAR LSD **

Does your owner's manual say your 3/S comes with a limited slip differential in the rear? The stock rear differential has a small and weak viscous coupling unit in it (VCU), which goes bad very quickly. The repair manual test procedure for the rear VCU is to jack up the car with all the wheels in the air and turn one of the rear wheels by hand. If the rear diff VCU is good, then the front wheels and other rear wheel will turn in the same direction. But if the rear VCU is blown, then the front wheels will not, but other rear wheel will turn in the opposite direction, which is exactly what we've seen on most cars. This is why we approached KAAZ to design a rear differential for us.

This LSD is great for street driving and for all kinds of racing. For drag racing, in a straight line full throttle acceleration it completely prevents the spinning of one wheel relatively to the other, thereby maximizing the rear traction and increasing acceleration.

In road racing and autocross, it acts as a torque-sensing differential, progressively increasing the differential lockup with the increase of the driveline torque that is sent to the rear axle. Due to the static preload, it also allows torque to be sent to the outside rear wheel when the inside rear wheel is in the air in tight autocross turns. This important feature improves the performance of the 3/S AWD system, especially on cars with upgraded power and suspension.

The KAAZ 3/S REAR LSD Specifications:

  • Clutch disks with KAAZ Super-Q treatment.
  • An improved half-shaft retainer utilizes the stock C-clips like the OEM diff.
  • Multi-disk clutch type
  • 1.5 way with a preload - More forward lockup for better acceleration, less engine braking lockup for better turn-in, preloaded with cone springs for high lateral G cornering.
  • Compatible with all-wheel steering.
  • Works in 5 and 6 speed rear ends, in the US, JDM, UK, all other markets.
  • Comes with a 2 liter can of KAAZ gear oil.

 

FROM THE KAAZ WEBSITE

All new Kaaz LSD needs to be broken-in to seat the clutch plates. Applying too much torque when the unit is new will cause damage to the clutch plates and may result in plates forming a angle fit. Once these plates form an angle fit, the LSD is unable to function at 100% efficiency. This will also result in more chattering noise under low speed turns. It is very IMPORTANT to perform the breaking procedure as described below.

All clutch type LSD's make chattering noise under low speed turns. This is normal for these types of LSD. The reason for this chattering noise under low speed turns is that the clutch plates are rubbing against each other thus giving you the limited slip action. If the breakin procedure is completed according to the diagram above and proper maintenance of the LSD is performed, the chattering noise will gradually decrease after accumulating some miles.

It is important to use 80W/90 GL-5 specification gear oil on Kaaz LSD. We highly recommend using the Kaaz LSD fluid. DO NOT USE SYNTHETIC BASE OIL ON KAAZ LSD. Kaaz LSD may not function smoothly. When one has a Kaaz LSD, it is important to do routine maintenance of LSD Oil. We recommend to change LSD oil every 5000 miles for daily driven and occassional track use vehicles. If the vehicle is full race,we recommend more frequent oil change.
