Is your Cylinder Head in it for the long haul?

We all know in order to get a million miles out of your engine you need to keep your engine cool, well lubricated, and perform regular maintenance. Let one of these slip... and your rig is going to wind up in the shop with you stuck waiting for the repair.

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 parts at up to 50% off OEM prices. While most believe aftermarket retailers sell cheap parts with zero warranty, packed in a beat-up box from who knows where, HHP is here to kick that stereotype to the curb. HHP provides Cylinder Heads with additional engine cooling properties and a 1-Year Parts Warranty. How’s that for an aftermarket part?

Need a little extra proof? Let's talk Cylinder Heads.

  • It can be hard trying to find the right parts but we can make the search easier. All HHP parts are crafted to strict OEM specifications which gives you proper fit and function.
  • Some places won't tell you where their parts come from. We aren't like some places. This cylinder head is manufactured and assembled in the U.S.A.
  • If you have the questions we will have the answers. We have ASE certified techs on staff to answer all of your technical questions.
  • If you are looking for the toughest parts in the industry, you came to the right place. This cylinder head is made with hard wearing materials for long lasting strength and durability. 
  • Saving money on parts has never been easier. Our parts have equal or better quality compared to the OE at a much lower price.
