Customer Reviews
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
100% recommend it is a good parts by par for five years and everything is good
Had a great experience with ordering correct engine gaskets for our 3208 caterpillar engine
Very thorough ! Confirmed order and great communications.
Great service affordable 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.
:) great service
The customer care response was very awesome. It was more than what I expected
The customer care response was very effective and timely
The response time was amazing
The availability of most of the parts that I wanted was also very awesome
Thanks keep it up
Rapid response! Excellent service!
Very helpful. Every question or request I had was answered quickly. I didn't have a parts book for my excavator but that was no problem for them. If you need parts for your Cat, give them a shot.
