Cummins 4B Inframe Engine Rebuild Kit, New (IF49553374B)

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.

• Restore and extend the life of your engine with a Inframe Rebuild kit built to OEM specifications to have proper fit and function within your engine.

• Additionally, provide long lasting durability with connecting rod and main bearings made with tri-metal materials.
• Drive comfortable knowing liquids are staying in place with the correct materials to ensure gaskets have excellent performance in functionality and sealability.
• Also, to ensure there is proper oil control, oil control rings are designed with precise tangential tension.
