Pricing: $23.12


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 22 Year Parts and Labor Warranty. How’s that for an aftermarket part?

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

  • To help get you another million miles, this gasket set is manufactured and assembled in an ISO 9001:2015 certified facility to ensure you receive consistent quality to depend on.

  • Built to OEM specifications, this fuel injector gasket set will have the correct fit within your engine to get you back up and running on the road in no time!
