Proform 66917C Hi-Performance Gear Drive

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.

Amazing part. Gives truck a little extra.

Came with everything I needed. Install was easy. Shipping was excellent.

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.

Just don't! It is noisy and offers no more precise drive for the came than a chain. Actually the back lash is bad.

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!

Just don't.. if you like buying useless crap and installing crap to have to take it back out because the timing marks line up but is totally wrong. Then buy this product. Otherwise save your money and buy something better.

Nice gear drive for the price I highly recommend this if your building on a budget not super noisy but you can defiantly hear itdoes need a little modification to stock timing cover for clearance but all in all good purchase!
