Think you know the truth about Pistons? 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 Pistons. 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, what?s left to want?

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

  • Replace your worn out piston with a brand new one built to OEM specifications. In other words, your engine will have a piston that fits just right!
  • Our quality standards meet or exceed the OEM with the only difference of a much lower price. Why overpay when you don't have to?
  • We ensure you'll receive quality because each piston is manufactured and assembled in an ISO 9001: 2008 certified facility. It doesn't get much better than that!
