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 Pistons, what’s left to want?

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

  • You'll receive a brand new piston that is manufactured and assembled in an ISO 9001:2008 certified facility! This ensures high quality and consistency.
  • Don't pay more for less! You'll get equal or better quality compared to the OE at a much lower price. That's more money saved!
  • To top it off, this piston is crafted to strict OE specifications which will give you proper fit and function. You can't beat that!
