great customer service and great product no complaints at all. kept me updated throughout the whole process on my deluxe kit

Super happy with everything I’ve ordered. Love the color and shipping was a breeze

Shipped timely and was professionally packed. Some would say the best packing job ever, that's what I would say I noticed. Smooth powder coating as well. Looks great.

HSP was great to work with only problem I had was my core return to longer than expected and we had a little argument cuz they sent back the wrong amount and was a key stroke rate but they fixed for fast no problem and apologized for the mistake I have and will continue with to recommend HSP to friends

Awesome thank you

Product was mid grade. Customer service was good with updates. I am disappointed with the intake

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.
