Top notch customer service and help from the sales team. Mike was awesome to work with and Blair kept me in the loop with the progress of my order 10/10 highly recommend HSP Diesel!!

Exactly what you said

They are awesome to deal with an have great products

I had some confusion with the shipment date, but they were very helpful and great to work with not only do I recommend HSP for how great they are to work with but the product itself was amazing. I got a new white bridge, hot and cold side charge pipe and new up pipes.

Shipping was fast powder coat was flawless. They did a great job

Website could use some fixing, customer support is pretty good though.

Everything was great, order was correct and the high flow bundle looks sick on my truck. I’m going to end buying another kit for my LBZ

Ordering over phone was great with the sales rep I spoke with

HSP is my favorite place to shop for quality upgrades. Most of it is flag red. Great products!

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!

Good I guess more my fault then anything bc body lift

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

Great quality easy install. Just felt it needed the cut ends taken care of I put oil resistant heat shrink on the ends so they wouldn’t fray

Nothing but the highest quality! My favorite place to upgrade from!

Great product, great company, great service.

Customer service was great, each time when I asked a question got a response within the next business day. The parts I bought are very well built and work as described by every video I have watched about your product line. Wish I had the money to buy more. Just wish I would have got more than one sticker or a banner for my garage like all the unboxing videos I’ve watched lol. On that note the packaging was so nice definitely not a chance of the product hitting or chipping the powder, overall I will be buying more of your products as my build moves forward and potential builds in the future. Thank you, Shawn DQ

Awesome! I had the upgraded bundle kit installed on my 2015 Chevy Dmax. Love the difference it made. Beautiful in Flag Red also. Perfectly made to fit! Thanks HSP Diesel!
