R-Line Wheel Hub Assemblies Fits select: 2002-2006 INFINITI Q45

• Generation 1 consists of a double-row contact ball bearings with a split inner ring. The split inner ring allows each ball bearing to rotate independently. Generation 1 does not include a hub, which must be purchased separately. • Generation 2 adds a flange that mounts directly to the brake and wheel mount. This eliminates the need for purchasing a separate hub, unlike Generation 1. • Generation 3, our most advanced step in hub development, offers a complete wheel hub assembly. Generation 3 differs from Generation 2 by adding a second flange that fixes the hub assembly to the suspension.
