Upon needing a special pulley application for a engine conversion on a piece of machinery, I found MDS had all of the bushings and pulleys that I needed to make a perfect fit and get the machine up and running. The order came in very timely manner, and packaging was perfect. I recommend this company to anyone needing good service and availability. Thanks to them everything went smoothly on my Machine repair.

Great product. Just as described. This company cares about the quality of their products and there service

The parts I needed were in stock and shipped out quickly to complete my repairs on time. I would definitely recommend and buy from them again.

I was extremely happy with the pricing and quality of the gears I ordered. Shipping was fast, got them sooner than expected.

Sprockets arrived on time, well packaged. Sent to a remote address no problem. Worked great.

Second time I have ordered from them. They send what you order and their measurements are correct.

We had a slight hiccup with the order, but Noah came through like a true champion. This is the epitome of great customer service!
