PowerBond by Dayco PB1663N harmonic balancer for the 2007-2011 Jeep Wrangler and other vehicles damps crankshaft vibration and carries the serpentine belt pulley. This engine harmonic balancer is sold as a single piece.
Cracks in the balancer, a pulley that wobbles or vibration you notice while driving can mean it is worn; any look should be done with the engine off and cool. A worn serpentine belt, a weak tensioner or a failing accessory pulley can produce similar noise and vibration, so find the cause before buying. Each engine takes one balancer, one per crankshaft.
The 2007-2011 Jeep Wrangler, the 2008-2010 Dodge Grand Caravan V6 3.3L or 3.8L and the 2008-2010 Chrysler Town & Country V6 3.3L or 3.8L all fit this balancer, and so do more vehicles.
