Customer Reviews
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
Steven & Propel Parts were a huge help! We were able to place a large order and get it shipped out same day to avoid a line down situation for a customer due to a lost component. The order was even submitted after the 3pm cutoff for same day shipments and we got it the next morning!
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.
To my country the company is doing great The products they market is good and Affordable. They can delivery to any country, stree free. Tested and trusted.

Customer service was great! There was a small problem with the part and they responded quickly and respectfully until was resolved! Highly recommended
Been buying from them for years and have almost never had an issue. The few times I had a question or something to handle, they have shown amazing customer service. Great product and a great company.
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
Great customer service. Prompt , knowledgeable and friendly service.
