What about warranty?

What is the Quaife warranty?

The Quaife ATB Limited-Slip Differential comes with a limited lifetime warranty.

If damage is caused to the Quaife due to faulty installation or overheating, the warranty may be voided and repair costs charged.

Our Exchange Final Drives include an additional 24 months warranty on all other final drive components, such as bearings and seals, or if the car is new we will match your manufacturer's warranty.

Will it affect my manufacturer's warranty?

The Quaife ATB will not affect your manufacturer's warranty.

We have been directly responsible for the sale of over 3,000 Quaife ATB differentials for BMWs and Mercedes worldwide, and not one of these has resulted in BMW or Mercedes claiming a fault or defect was as a result of the Quaife installation.

Product reliability is of paramount importance to us. We have been in the BMW tuning arena since 1985 (and were a BMW dealership ourselves for 15 years prior to that). We will only offer products that have been fully tested and are guaranteed only to affect BMW and Mercedes ownership in a truly positive way. If your BMW or Mercedes dealer suggests otherwise, give us a call!
