Review: $65 -$100 dollars to maybe rent a kit from auto part store.. only to get home and realize it doesn't work for your car!!!! Happened 3 times before I found this tool. 2007 gm sierra classic v vin 4.8L. Super simple use. 1 minute after opening box the harmonic balancer was re installed with no fuss. Great price, great quality, perfect fit, and I didn't have to argue with the high schoolers at parts house.
Review: fast delivery works fantastic
