Description

Think you know the truth about Piston 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 new Piston Kits. 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 Piston Kits, what?s left to want?

Need a little extra proof? Let?s talk Pistons.

  • This brand new piston kit is manufactured and assembled in an ISO 9001:2008 certified facility. This ensures great quality and consistency.
  • Also, strict OE specifications are met giving you the proper fit and function that you need.
  • Want more cash in your wallet? You got it! You’ll get equal or better quality compared to the OE at a much lower price. You can’t beat that!
