Customer service was excellent today! I have never had a company go behind the scenes to see what was happening with my payment error and resolve it so I could complete my order without having to do it all over again. Hats off to Propel Parts!
-
Steven & Propel Parts were a huge help! We were able to place a large order and get it shipped out same day to avoid a line down situation for a customer due to a lost component. The order was even submitted after the 3pm cutoff for same day shipments and we got it the next morning!

Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you.
