Please refer to the OIL F.A.Q. found HERE

When should I overhaul my KAAZ LSD?
To cancel out rumors about our limited slip differential constantly needing an overhaul, we recommend overhauls based upon vehicle usage and unit age. Keep in mind that clutch type differential's will produce friction wear, it is crucial that a properly functional unit is at hand in order to provide exceptional performance when compared to a poorly maintenance or worn-out unit. From our years of experience every vehicle varies, whether it be for track racing or street driving. The best way to determine if your vehicle needs an overhaul is to check with a technician or do simple test to see if your unit is functioning properly. There is speculation that our units often need overhauling however, in actuality within the past 10+ years of selling thousands of KAAZ Limited Slip Differential's in Northern America alone, our selling rate of overhaul kits are very minimal when compared to our overall unit sales rates. It is best that you contact a local technician or send your unit to KAAZ USA for inspection if you feel your L.S.D. is in need of an overhaul.

Does KAAZ USA provide service work?
Yes, WE HAVE A FULL FACTORY SERVICE FACILITY LOCATED IN USA. What sets our company apart from others is our technical customer service. We can install, adjust, inspect and perform just about any procedure when concerning a KAAZ differential. In fact we've actually serviced and repaired many of our competitors units as well. Inquire within for more information. If you do not have a trusted qualified technician available we'd be happy to assist you in any service work needed. Please contact us for further information.

My unit makes chattering noise is this normal?
Many clutch type differentials do produce chattering noises. This should only occur during low speed turns or at the initial point of engagement. You may feel or hear more chattering in front wheel drive platforms due to the differential being located at the front of the vehicle. SuperQ units are designed to be virtually noiseless when compared to most differentials on the market, if you are concerned about chattering then this unit is suggested for you.

What is this SuperQ differential?
The SuperQ unit is an exclusive KAAZ USA product. Basically the next step was taken to improving a great product, our SuperQ line features superior surface treatment technology to allow extremely smooth operational usage with the least amount of chattering noise. SuperQ units also increase in lifespan by about 15%-30% longevity. There is also no break in procedure needed! Please check out more detail information HERE.

Do I need to use a genuine KAAZ speedo gear for my Honda unit?

On most of our front wheel drive Honda Limited Slip Differentials we provide with the unit our genuine speedo gear replacement. During manufacturing we precisely cut grooves onto the differential case surface area in order to drive the speedo gear. The pattern in which we cut are not identical to OEM specifications therefore the KAAZ speedo gear must be used. You must replace your OEM speedo gear with a KAAZ unit, this may be a reason in which your speedometer does not work properly

Are KAAZ L.S.D's adjustable?
YES KAAZ LIMITED SLIP DIFFERENTIALS ARE FULLY ADJUSTABLE. Here are some features that may be adjusted:
*Initial Torque Settings (higher or lower),
*Locking Rate adjust ability (decreasing the locking rate for a more milder reacting differential)
*Pressure Ring reversal (Depending on configuration)
*Side gear changeably (on specific models)
There are many optional parts available to help configure your differential for your specific needs, as with different types of racing there are various configurations designed to work with your type of racing style. You can take a look at our extensive optional parts listing HERE. Contact KAAZ USA for assistance on configuring your differential!

I heard KAAZ manufactures for other "well-known" companies, is this true?
Do to respect for these parties, we can only mention, yes: KAAZ does manufacture for 3rd party companies that are "well-known" in the market for performance products. Our technology and products are not only trusted through end-users and racers but other companies that believe in the KAAZ capabilities as well.


What's the difference between KAAZ L.S.D's and other units that are torque bias?
Many assume limited slip differential's are all the same, however we'd like to point out some differences which separate each unit apart. A clutch type differential is beneficial to road racing due to liner/faster lockup with more predictability. On Torque Biasing units when one wheel lifts, there comes a reaction where the differential now carries a open differential character due to power only being transfered to one wheel, however when the lifted wheel makes contact there is a time frame in which progressive build-up  is needed in order to transfer full power. This can be a downfall for road racing or rally racing since the vehicle is more then likely subject to wheel lift. The KAAZ LSD actually provides power even during one-wheel-contacts.

How to I perform a Break-in Procedure on my KAAZ unit?

Only non-SuperQ LSD's must 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. A video will be added shortly to explain this procedure.

Why do KAAZ LSD's cost less then other brands?
KAAZ has been in the machinery industry since 1922 far longer then most of our competitors. With more then 80 years experience we are able to produce products more efficiently and with lower cost. KAAZ does not allow itself to manufacture products for maximum profit using inferior materials.
