“I would have gave a 5 star rating if it didn't take a month to get something that the web says is in stock. No instructions came with the thermastate housing kit but very easy to install. Looks great.”

“Very good quality products built to last and customer service is great with any questions you may have. Only problem I’ve had was waiting a couple months to receive my high flow bundle kit. Other than that parts looked amazing and very well built. Will be building my entire lb7 with hsp parts!”

Thank you for sending this picture and for your feedback! That is a little mark from the hanger that the product was hung by in powder coating. It should not affect your product or the quality of the powder at all! If it does affect the powder, please do not hesitate to reach out to us, we're always happy to help! (:

“I bought traction bars and the intake bundle from HSP for my LBZ and it looks great and functions fantastically but my only reason for the 4 starts is because it seems there isn’t a whole lot of powder on the pipes. In my experience it’s a lot harder to scratch something powder coated but my cold side pipe and Intake seemed to scuff pretty easily with a tiny bump. But I will recommend HSP to anyone interested”

“I recently got traction bars for my 2002 2500hd duramax. handling is so smooth under heavy acceleration. Easy installation but the only problem I had was threading in the heim joints. I had to use tap to clean the treads from the powder coating. Other than that I'm satisfied.”

“The customer service was awesome! That's for sure a 10 out of 10! There was only 2 little issues which 1 isn't even HSP product related as much but would be great if you guys could send an instruction manuel how to put the pieces together just give ideas how to approach certain things since that would help people like me who would try to tackle this project alone and 2. It would be nice if you guys would supply a plug for the injector return line fitting kinda like WC Fab does (which by the way they do send a manuel on how to overall in general install their kits) which again no means do I mean send a whole instruction manuel but just kinda how they do in small detail to point you into the right direction how the parts should go. Besides that amazing quality and craftsmanship and I will be purchasing again from you guys soon for the manifolds! P.s. the truck these parts went on was a 2016 GMC 2500!”

“Great product. The fitment was nearly perfect. I was worried the powder coat would get chipped and scratched up during install but didn’t have any issues at all. The only reason I’m rating this 4 stars is I had to buy new Y bridge gaskets which aren’t included. I never like to reuse old gaskets.”

Thank you so much for your feedback Dave! We're so happy that everything fit nicely for you, we take great pride in the fitment and quality of our products! As you have found out, we do not include the Y-Bridge gaskets in our bridge kits. We recommend reusing the original bridge to intake runner gaskets to allow for ease of installation. In our experience, we found the new much thicker gaskets tend to roll when fitted down into the tapered section in the valley of the engine. (:

“Good quality parts that look and function great. Bought the pre filter bag that fit exact! 4 star for fitment of the Pipe and system. Felt a little like a universal fitment system with pipe lineup.”
