Detailed Description
An engine harmonic balancer uses an internal damping layer to reduce crankshaft vibration while keeping the accessory drive pulley aligned. Over time, the rubber or fluid damping material can deteriorate, allowing the outer pulley section to shift and creating belt misalignment. When that happens, the balancer should be replaced to help protect the crankshaft and restore normal engine operation. ATP Parts 102284 is engineered as an OE Replacement Balancer for vehicles that use a serpentine belt setup and a 6-groove balancer configuration.
