Very lowkey seller for genuine cummins parts, specially the for 12 valve! great prices and extremely fast shipping. Would recommend to anyone for business.

Bought from you a few times, always good prices, fast shipping, and quality cummins products! Always come to you first for parts.

Bought a lift pump, did not open it and tried to return it a few days after receiving it but I was not allowed to do so and I basically lost my money. Spoke to a customer service person named Rok and did not help whatsoever amd does the bare minimum. the refund policy is ridiculous and even if the wrong part is ordered you are screwed and have to loss your money. I will never be giving them business again. No wonder they are called poor man’s diesel with all their poor customer service and business practices these poor customers are not getting help with right parts and are getting scammed by them
