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.

  • This rebuild kit is built to OEM specifications with equal or better quality than the OE at a much lower price. You can’t beat that!
  • This kit contains all brand new parts that are manufactured and assembled in an ISO 9001:2008 certified facility ensuring proper engine fitment and function. Plus, no core charge since it is all new parts. More money in your pocket!
  • Our CNC turned pistons to precise tolerances gives you excellent quality paired with consistency.
  • These piston pins are not your average pins. They are hardened and tempered for improved strength and wear resistance.
  • Keep your engine running till the cows come home with connecting rods and main bearings crafted with tri-metal for durability.
  • Let’s seal the deal with gaskets made from the correct materials for excellent performance in functionality and sealability.
  • We deliver the highest quality of sealing products that are proudly made in the USA, using 100% asbestos-free materials.
  • Our on staff ASE certified techs are here to help restore your diesel to good working condition, extending it’s life.
