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 sleep soundly knowing all parts are built to OEM specifications ensuring proper fitment and function.
  • Get the best of both worlds with a rebuild kit equal or better quality compared to the OE at a much lower price. You can’t beat that!
  • Go the extra mile, or a million extra miles with piston pins hardened and tempered for improved strength and wear resistance. Ever heard of the little engine that could? We bet it had these piston pins.
  • Want durability? You got it! Rod and main bearings are constructed with a tri-metal material to extend the life of your engine.
  • Trust the experts with a rebuild kit manufactured and assembled in an ISO 9001:2008 certified facility. Simply put, it’s quality and consistency you can count on.
  • Maximize your engine with CNC turned pistons to precise tolerances giving you the reliability you expect from HHP.
  • You are never settling for sub-par parts! The gaskets used in this rebuild kit are made of the correct  materials for excellent performance in functionality and leak free durability. It doesn’t get much better than that!
  • All of the sealing products in this kit are proudly made in the USA and 100% asbestos-free.
  • This new rebuild kit will restore your engine to good working order and extend the life of it into the next generation of the family business.
