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.

  • Trust the experts with a brand new piston that's been manufactured and assembled in an ISO 9001: 2008 certified facility. You'll get excellent quality and consistency you can count on!
  • Also, this piston is built to OEM specifications, meaning it will fit your engine just right!
  • To top it off, you don't have to overpay! With HHP you'll get equal or better quality compared to the OEM at a much lower price.
