Product Details

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. 4BTdiesel is here to set the record straight; we only sell new piston. 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.

  • Trust the experts with a piston body manufactured and assembled in an ISO 9001:2008 certified facility. Simply put, it’s quality and consistency you can count on.
  • Put the OEM to shame! Your piston will be brand new andย haveย equal or better qualityย compared to the OE for aย much lower price!
  • Get back up and running in no time. Your part is made to OEM specifications, giving you proper fit and function.
