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

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

  • Get theย best of both worldsย when you buy from 4BTdiesel! Our rebuild kits are built toย OEM specificationsย providing youย equal or better qualityย than the OE at aย much lower cost.
  • Since this is aย brand newย rebuild kitย manufactured and assembled in an ISO 9001:2008 certified facility,ย you will be getting theย quality and consistencyย you demand. Plus,ย no core charge!ย Giving youย more money in your pocket!
  • Beef up your engine withย CNC turned pistons to precise tolerances!
  • By using theย correctย  gasket materialsย you will haveย leak free durability and excellent performanceย in functionality.
  • Think your tough? These piston pins areย hardened and temperedย for improvedย strength and wear resistance.
  • Tri-metalย connecting rod and main bearings are used forย durability, giving you optimal performance.
  • The sealing products in this kit areย proudly made in the USA, using 100% asbestos-free materials.ย I think this speaks for itself.
  • Support from ourย on staff ASE techsย can help restore your engine toย good working conditionย andย extending the lifeย of it for another million miles.
