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 Cylinder Head Gasket Sets 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 Cylinder Head Gasket Sets 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 Cylinder Head Gasket Sets fabricated for unstoppable performance and a 2-year warranty. How’s that for an aftermarket part?
