HSP Diesel

HSP is great to work with. I am still having login issues with the website, but getting the opportunity to work with the sales team is great, the guys know what they are doing, are ready to offer necessary information right out of the gate, and keep the hassle out of buying truck parts. Keep up the great work guys, I'm nearly complete obtaining the full LLY high flow bundle, and cannot wait to get the truck running with these parts added to the new engine I'm putting together!

Great experience start to finish.

One of the best experiences I’ve ever had with customer service and parts that scream performance with looks to back it up!

HSP customer service is unbeatable jist like the products they sell. After having my order confirmed they were with me the whole way, even after when i had questions. Package came quicker than expected. . Go ahead and order it, you will be glad you went with these guys.

Customer service was fantastic, they were very communicative about potential delays and responsive to questions, production and shipping was much faster than they had estimated , the installation instructions were easy to locate and very clear
