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.

When I had questions, they were answered quickly and kindly.

Thank you!!

I’ve been ordering parts from propel for about 3 years & counting. I live in Hawaii where we have a hard time getting parts especially for decent prices with fast shipping. I've been 100% satisfied with the company and the customer service and will continue to use them. I recommend propel to everyone here in Hawaii and we are all happy to have you guys. Thank you!!!
