Product Details

Think you know the truth about Piston Kits? 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?ย 

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 sellย new Piston Kits.ย On top of only offering premium quality parts, we also make sure youย save up to 50% off OEM prices.ย So, when it comes to your Piston Kit, what’s left to want?ย 

Need a little extra proof? Let’s talk Piston Kits.

  • There is no doubt that thisย brand new piston kitย isย manufactured and assembled in an ISO 9001:2015 certified facility.ย This ensures excellent quality and consistency of parts.
  • Wantย proper clearances?ย We’ve got you covered!ย Clearances will be maintainedย due to this piston beingย computer control machined.
  • Plus, yourย tolerances will be preciseย due toย CNC turning of the piston.ย Somewhat close won’t cut itย for us here at 4BTdiesel.
  • Piston pinsย are included within this piston kit. They areย hardened and tempered for improved strength and wear resistance, keeping your rig up and running for another million miles.ย 
  • Additionally, you’ll getย equal or better quality compared to the OE at a much lower price.ย To top it off, this piston kit will haveย proper fit and functionย because it isย crafted to strict OE specifications.
  • To top it off, kicking your worn out piston to the curb and replacing it with a new one will lead to top-notch engine performance.ย
