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.

  • Do you have good existing pistons? If so, this re-ring kit is a cost-effective option that allows you to reuse your good existing pistons and save some cash!
  • Upgrade your engine with a tri-metal construction rod and main bearings for durability. Think you’re tough? Try the new piston rings coated with wear resistant materials for extended wear characteristics.
  • Additionally, our sealing products are 100% asbestos free as well as made in the USA! You can’t beat that!
  • The new oil control rings included are designed with precise tangential tension to keep your oil where the oil belongs.
  • You’ll get a new re-ring kit that has excellent quality and consistency because it is manufactured and assembled in an ISO 9001: 2008 certified facility. Additionally, the cylinder liners included are induction hardened to reduce bore wear.
  • There is no core charge and all new parts are included which will keep your engine up and running for another million miles!
  • Correct materials are used in the crafting of the gaskets, giving you maximum performance in functionality and sealability.
  • This inframe re-ring kit conforms to strict OEM specifications ensuring proper fit and functionality. Also, why overpay? You’ll get equal or better quality compared to the OE at a much lower price.
