Customer Reviews
Propel Parts provided quality parts for my Caterpillar needs at a very fair price. Shipping to my international location was very fast. took about a week for the parts to get here. Seller is also responsive with my inquiry.
Thanks again
Great Customer Service!
Had some difficulties with the website. Contacted customer service. Once I communicated the issues I was having Steven worked through getting my order processed and making sure I got my receipt and all issues resolved. Perfect!
Science I buy parts from propel parts I don’t have to spend too much down time always on time and good service
Great place for Cat parts!
Had some shipping difficulties, but everything was made right. Parts were perfect and an excellent price. Thanks!
Rapid response! Excellent service!
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!!!
Fast communication, and very Helpful!
Propel parts is a good Cat vendor that provides a top notch service to customers from ordering to delivery. Their after sales service is really impressive.
I almost want to cry ;( writing this review because I dont want people to find out about them and rather keep them in my pocket but they deserve it…
This company is great with Quality Products at amazing prices! Sometimes, their website is not the most accurate but is user friendly and if you got questions they will call back and are very prompt in responding via a call or text to verify inventory before placing an order.
I really appreciate and look forward to continuing to work with you all especially Anthony — he is amazing & the best!!!
