Description

Think you know the truth about Aftermarket Rebuild Kits? We’d bet you’d be surprised.
It’s no secret, rebuilding your rig is one of the most labor (and wallet) intensive repairs out there. Sure, you want your engine to last another million miles but you also want the best price; so what should you choose- OEM or Aftermarket?

When it comes to engine parts, the aftermarket often gets a bad rep. The idea that aftermarket retailers sell cheap parts with zero warranty, delivered in a beat-up box written in another language couldn’t be further from the truth. HHP is here to set the record straight; we only sell Rebuild Kits with new parts, zero core charges, and a 2-Year Parts and Labor Warranty. On top of only offering premium quality parts, we also make sure you save up to 50% off OEM prices. So, when it comes to your rebuild, what’s left to want?

Need a little extra proof? Let’s talk Rebuild Kits.

  • Keep your engine running till the cows come home with a brand new inframe rebuild kit manufactured and assembled in an ISO 9001:2008 certified facility.  You’ll be getting the quality and consistency your rig needs. All new parts equals no core charge and more money in your pocket!
  • This rebuild kit is built to OEM specifications, ensuring proper engine fitment and function. Stricter than a dad with his daughter’s boyfriend!
  • You’ll save a boatload of cash with this kit! You’ll get equal or better than the OE at a much lower price.
  • With this rebuild kit you will be making your diesel great again and extending it’s life.
  • Our CNC turned pistons to precise tolerances are tougher than your average Joe, giving you the uniformity and strength you need.
  • We all know that one guy with the puddle under his rig. You won’t have to worry about being that guy since we use the correct gasket materials throughout for leak free durability and excellent performance.
  • Think you’re tough? These connecting rod and main bearings are crafted with tri-metal for endurance.
  • Keep your oil where it is supposed to be with oil control rings designed with precise tangential tension for proper oil control.
  • We emphasize quality at HHP. That is why the sealing products are proudly made in the USA, using 100% asbestos-free material.
