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.

  • Extend and restore the life of your engine today with a brand new Inframe Rebuild Kit built to OEM specifications assuring proper fit and function within your engine.
  • Sleep soundly knowing OEM gasket materials are used throughout your kit to provide leak free durability
  • Get more bang for your buck! It doesn’t get better than equal or better quality compared to the OE, especially when it’s at a much lower cost. 
  • That’s not the only way HHP will help save you some money. All parts are brand new and have no core charge! You can’t beat that!
  • Think you’re tough? For improved strength and wear resistance, the piston pins included are hardened and tempered. Now that’s tough enough to keep you going for another million miles
  • Get back up and running in no time with computer controlled piston machining to maintain proper clearances. 
  • At HHP, we know quality and consistency are always top priorities. We will provide you with an Inframe Rebuild Kit manufactured and assembled in an ISO 9001:2008 certified facility ensuring your top priorities are met. 
  • Keep your oil where it’s supposed to be. The oil control rings included with the piston kit are designed with precise tangential tension for proper oil control.  
  • Make your diesel great again! Sealing products are proudly made in the USA and made from 100% asbestos-free material.
  • Made to make your engine hard as nails, tri-metal connecting rods and main bearing are included for long lasting strength and durability.
