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.

  • Restore and extend the life of your engine with a brand new Inframe Rebuild Kit built to OEM specifications to ensure proper fit and function within your rig.
  • We emphasize quality here at HHP. To make certain you receive the quality and consistency you depend on, we make sure your rebuild kit is manufactured and assembled in an ISO 9001:2008 certified facility.
  • Fortify your engine with the correct gasket materials to be used throughout your rebuild kit for excellent performance in leak free durability. 
  • Sleep soundly knowing proper clearances within your engine are being maintained with computer controlled piston machining.
  • Want your truck as hard as nails? You got it! For improved strength and wear resistance, piston pins are hardened and tempered.
  • Make your diesel great again with sealing products crafted with 100% asbestos-free materials and proudly made in the USA!
  • Why sacrifice quality if you don’t have to? Pistons are CNC turned to precise tolerances and oil control rings are designed with precise tangential tension for proper oil control. You can’t beat that!
  • Go the extra mile, or a million extra miles with rod and main bearings constructed with tri-metal materials for durability. 
  • Put the OE to shame! For no core charges and a much lower price compared to the OE, you will receive brand new parts with equal or better quality!
