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.

  • You’ll never lose sleep wondering if you made the right choice with HHP! Our rebuild kits are made of strict OEM specifications giving you equal or better quality compared to the OE, at a much lower price.
  • Plus, this brand new rebuild kit is manufactured and assembled in an ISO 9001:2008 certified facility, ensuring proper engine fitment and function. And since it is brand new, there is no core charge! That is more coin in your pocket!
  • Receive unrelenting power with CNC turned pistons for precise tolerances. Simply put, quality and consistency you can count on.
  • Think you’re tough? These tri-metal connecting rod and main bearings are built with durability and will give you a run for your money.
  • These piston pins are hardened and tempered for improved strength and wear resistance. Ever hear of the Little Engine that could? I heard he had these piston pins and he’s racked up another million miles on that bad boy.
  • Do you want excellent performance in functionality and sealability? Of course you do! And that is exactly what you will get with these gaskets made with the correct materials.
  • Additionally, the sealing products are proudly made in the USA, using 100% asbestos-free material. I think this speaks for itself!
  • Let our on staff ASE certified techs help make your diesel great again and extend it’s life.
