Grateful I found this company!
I’m grateful I found this company! They answer the phone every time plus the parts are packaged very well!! Even the angriest mailman couldn’t damage your parts! lol The parts showed up as planned and for being aftermarket the quality seems to be good!! The warranty is the same as CAT. Thank you Daniel!!! -
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!

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.
