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.

  • Each piston is made to OEM specifications because we understand proper fit and function is critical when it comes to your engine.
