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 warrantyย 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 to make your rig great again?Trust 4BTdieselย with a rebuild that restores your engine toย good working condition and keeps it running for another million or more miles.
  • Give your engine a backbone.ย Tri-metalย connecting rods and main bearings are included to forย long lasting strength and durability.
  • Don’t settle for sub-par quality!ย We put theย OE to shame with exceptional quality and consistency.ย This rebuild kit goes through a state of the art manufacturing and assembling process at anย ISO 9001:2008 certified facility.
  • Piston pins are hardened and tempered for improved strength and wear resistance.ย Ever heard of the little engine that could? We bet he had these piston pins.ย 
  • Why overpay? Our qualityย meets or exceeds the OE’s at a much lower price,ย giving you the value you deserve.ย But, the fact thatย all new partsย are included and there isย no core charge keeps cash in your wallet!
  • Let’s talk Pistons. You canย rest assuredย the pistons included areย CNC turned to precise tolerances,ย and areย computer control machined to proper clearances.ย It doesn’t get much better than that!
  • Want to keep your oil where it needs to be? The sealing products within this kit areย proudly USA madeย and useย 100% Asbestos-Free material.ย Additionally, theย correct materialsย are used in the crafting of the gaskets ensuringย optimalย performance in functionality and sealability.
  • Leakage? Never heard of it, the gasket materials are composed of the OEM’s to give youย leak free durability and peace of mind when out on the road.
  • Oil control ringsย are included and they are designed withย precise tangential tension for proper oil control.ย You can’t beat that!
  • You’ll getย back up and running in no timeย since all parts areย crafted to strict OEM specifications,ย giving you theย best of fit and function.
