Product Details

Think you know the truth about Aftermarket Rebuild 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?

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 Rebuild Kits with new parts, zero core charges, and a 6-month warranty. 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 rebuild, what’s left to want?

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

  • Want lasting quality and consistency? You’ve got it with an Inframe Rebuilt Kit manufactured and assembled in an ISO 9001:2008 certified facility.ย 
  • Let us save you some money. All parts of your rebuild kit are brand new and do not include any core charges!ย 
  • Maximize strength within your engine using tri-metal constructed rod and main bearings for durability.
  • To help you get where you need to go, pistons are CNC turned to precise tolerances while piston pins are hardened and tempered for improved strength and wear resistance.ย 
  • That’s not all! Maintain proper clearances with computer controlled piston machiningย and go get yourself another million miles.ย 
  • Sleep soundly knowing your Overhaul kit isย made to OEM specifications to ensure first classย fit and function within your engine.ย 
  • Be able to trust your engine is properly lubricated.100% asbestos-free sealing productsย that were made in America are used.
  • Stop paying ridiculous OE prices! Extend and improve the life of your engine with the same, if not better quality compared to the OE at a much lower price! It’s a win-win situation!
