Think you know the truth about OE Rebuild Kits? We'd bet you'd be surprised.

If we tried to sell you used parts for your Rebuild, you'd call us crazy. But, if you've ever bought an OE Rebuild Kit, you may have unknowingly paid a premium for used parts! Replacing used parts with more used parts!?! That sure doesn't sit right with us. How about you?

When it comes to engine parts, the aftermarket often gets a bad rep. The idea that the aftermarket retailers sell cheap parts with zero warranty, delivered in a beat-up box written in another language is just plain wrong. 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. Now, doesn't that sound more like the parts you should be installing in the biggest investment of your career?

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

  • Our Rebuild Kits are built to OEM specifications, giving you proper fit and function. You'll also save up to 50% off OEM prices.
  • Buy quality for your engine. Every HHP diesel rebuild kit is assembled in an ISO 9000:2008 certified facility, providing consistent quality- every time.
  • Count on unstoppable performance with hardened and tempered piston pints, tri-metal rod and main bearings for added strength.
  • Simplify the rebuild process, as every overhaul kit is packed in subassemblies by function, and o-rings are individually numbered for easy installation.
  • When it comes to rebuilds, no detail is too small. Even the USA-made sealing materials are 100% Asbestos-free.
  • Go a million miles and beyond with a Oil Control Rings designed with precise tangential tension for proper oil control and long-term durability.
  • We have ASE certified techs on staff to answer all of your technical questions. You'll be back up and running in no time!
