These aren't your grandpa’s gaskets.

A blown gasket can be anything from a minor annoyance to leaving you stranded on the side of the road. You don’t have to put up with whatever gasket you can get your hands on; our gaskets are engineered to withstand anything you throw at it and last well into another million miles. No doubt about it, these are some of the best gaskets on the market.

It's no secret that diesel engine parts can cost an arm and a leg. That’s where HHP steps in. We offer premium aftermarket gaskets at up to 50% off OEM prices. While most believe aftermarket retailers sell cheap gaskets with zero warranty, packed in a dusty box from who knows where, HHP is here to kick that stereotype to the curb. HHP provides gaskets fabricated for unstoppable performance and a 2 Year Parts and Labor Warranty. How’s that for an aftermarket part?

Need a little extra proof? Let's talk shop.

  • Do you know where your parts come from? Now you do! You will receive a brand new cylinder head gasket set that is manufactured and assembled in an ISO 9001:2015 certified facility. This ensures quality and consistency.
  • All HHP parts are crafted to strict OEM specifications which gives you proper fit and function. This means your new cylinder head gasket set will fit like a glove in your engine.
  • We don't like garbage and you don't deserve it. We use correct materials ensuring gaskets have excellent performance in functionality and sealability.
  • We focus on quality and dependability. This is why we offer USA made sealing products that use 100% Asbestos-Free Material.
  • Give your bank account a break and shop with HHP. Our parts have equal or better quality compared to the OE at a much lower price.
