★★★★★

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.

★★★★★

Awesome and diligent support. Would definitely recommend

★★★★★

Excellent experience.
Mike has been very helpful. I am looking forward to keep doing business with them

★★★★☆

I would give 5 stars but my first time ordering from here and using aftermarket parts. The price is reasonable comparing to original Cat parts and the customer support is great and hoping to do more business with them
