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.

  • Why buy reman when you can buy new? Our 12 Valve Cylinder Head includes a new forged head casting with higher nickel content for superior strength and durability.
  • New valves, spring, retainers, keepers, and pre-installed cam bearings, this Cylinder Head includes everything you need to go another million miles.
  • Keep your engine running at peak performance, with a new head design for higher coolant flow compliments of widened passages and a thicker deck.
  • Why overpay? Equal or better quality compared to the OE at a much lower price.
  • Built to OEM specifications, giving you proper fit and function.
