Which blenders does this jar fit?

It is made for KitchenAid KSB560-series blenders. Check your model number on the base before ordering, since other KitchenAid lines use different jars.

Does it include the blade and lid?

The assembly includes the jar, blade and base. A lid is not part of this assembly, so reuse the lid from your old jar if it is still in good shape.

Is this a genuine KitchenAid part?

It is sold as an OEM KitchenAid component, so it matches the original fit and threading rather than a generic third-party jar.

Will it fix leaks from my old jar?

A new jar and base restore the seal at the bottom, which is where most leaks start. If the leak comes from a worn gasket elsewhere, check that part too.

Can I put the jar in the dishwasher?

The jar and blade are generally washed by hand to protect the blade and base. Follow the care instructions that came with your blender.

Is it worth repairing instead of buying a new blender?

If your motor base still runs well, replacing the jar keeps a working machine going. If the motor or controls are failing too, a new blender may make more sense.
