Customer Reviews
Everything fine, thank you. The only thing with which I had a problem in your Software, is that when I have more than 10 different items on the list, I can't scroll to the first ones. But besides that, I am very happy in going on with buying your parts.

Science I buy parts from propel parts I don’t have to spend too much down time always on time and good service
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.
Quick Respond.
The quick respond much appreciated.
Keep this up.
Great customer service.

Been buying from them for years and have almost never had an issue. The few times I had a question or something to handle, they have shown amazing customer service. Great product and a great company.
Had a great experience with ordering correct engine gaskets for our 3208 caterpillar engine
