Quality product and stronger than factory. What should have been attached from the factory.
Great parts easy process and shipping…
Great parts easy process and shipping as well good prices
Part failed 2 minutes after installation
The gasket lasted 2 minutes and blew out. Sucks after putting in 4hrs of labor to have to redo it again for a stupid $20 gasket.
Great customer service
I got an email the morning after I placed my order saying that due to health issues it would be a few days before my order could be shipped and offered a refund if I wanted. I wasn’t in a hurry so I declined, as promised my order was shipped three days later. All my parts were in great shape and I’m very happy with the low prices.
abfjv 12 valve transfer pump defect
Ordered a abfjv 12 valve transfer pump and it came with a defect. The inlet check valve was missing from pump. Tried for months to get a replacement or return and was ignored and or put off the entire time. Still have not had a replacement or am able to return product. Never buying from this site again. Very "poor" customer service.
Parts showed quickly with no issues
I ordered my part more than a week ago.
Update* was told on the 23rd it would ship either the next day or yesterday (Fri or Mon). At 7pm last night (Mon) when I reached out to find out what was going on, Rok Hefti immediately replied with "I refunded your money so you can buy from a better supplier"
I would advise avoiding getting scammed by these people.
I ordered my part more than a week ago.
It hasnt even shipped yet, and you are seriously sending me a request for a review?. This is my first and likely last time I'll order from you, but if you want an honest and fair review, send the review request 3 days after the part is scheduled to be delivered.
Cummins parts cheap and quick!
Great place for CUMMINS parts

Quality Parts, Cares for YOU!
Had an issue due to the mailing service, but PMD quickly resolved it and made sure to send my package with replacement parts. Authentic Cummins DCEC parts, great prices, and great customer service.
Everything came and they let me know…
Everything came and they let me know that some items (60 lb. Springs) were backordered. I appreciated them letting me know, and everything still showed up quickly.
Received
Received - parts were OEM Cummins as advertized - Well packaged arrived in pristine condition - Excellent! Thank you!
Exceptionally happy with this transaction
Merchant advertised a part I needed which was right around half the price of those sold from other, more popular merchants. Item arrived to my house in Washington state from the merchant's location in Florida in ONE WEEK! Item was brand new in OEM packaging. I couldn't be happier with this merchant!
Fast shipping
