    Well I was after that gear whine and the Proform Gear Drive 66917C gave me exactly what I wanted. Not very noticeable on the freeway, but the drive has quite a whine going through the gears (smiles). Nice product, quality seems good, and the price was right!

    Great product all around. made out of good steel and instructions are there just make sure you install the dog bone like it says. With that said the only 1 down side is the sound its noisy enough just the sound is not quite what i wanted sounded like i ran out of ps fluid so back to chain for me. Accuracy wise it was only 2 degrees slop if that so it is well made.

    Product came well packaged and in a timely manner. Product is fairly priced, it came with easy to follo directions. I have had several gear drives, while this is noisy, it is far less than some of the others I have had. However the others were almost 2 1/2 times more expensive. So if you are looking for noisy, it’s the one, if you are looking for real noisy, well. I will say that it is well worth the price, great quality. Thank you for your quality and service.
