Description

Is your Cylinder Head in it for the long haul?

We all know in order to get a million of 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 warranty. How’s that for an aftermarket part?

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

  • Why buy new, when you can buy remanufactured and save? This cylinder head is magnafluxed to detect cracks, then furnace welded if needed. Under lower limit heads are thermal cast, 100% air decay and wet tested, and finished by chasing the threads and providing a machined finish.

  • Hand reassembled and thoroughly checked, this Cylinder Head includes everything you need to go another million miles.
