Quick response,good quality parts,favourable prices and always deliver on time
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.

Amazing Help.
I don't know who I spoke with, but they were helpful. We will be buying those parts shortly.
Good Stuff.
We have had a couple shipping issues, but each time they made it right and we ended up getting what we need. Quality parts at half the price of OEM.
Great place for Cat parts!

Great company to deal with. Answered my questions with detail and shipped me the part in good time! I will be dealing with them more in the future!
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.
Excellent service and very very good service
