Perfect Redesigned Over Original Parts Too!

The harmonic balancer failed on our late 2006 X5 3.0d failed just recently - the inner track separated from the outer and it was spinning freely. Bought this one (OEM part, fantastic price and insanely fast shipping by DHL as always). We installed this yesterday, and what a difference. I should note that the new one has been improved / redesigned over the original one that was on our car. The new balancer has twice as much rubber material in the core (far more stability and overall integrity) and also has ventilating holes on the backside of the center support plate, so it won't cook the rubber under high load and will likely last a LOT longer. I can't say if the aftermarket versions have these improvements, but in all honesty if they DON'T - you'd be mad not to stick with this updated OEM part. The engine in the X5 is smooth and happy again, and we're all absolutely certain there has been an overall noise reduction from this replacement. Totally happy!

Some of the reviewers above may have been rewarded for their positive & negative reviews. We don't hold anything back.
