Cummins 4B Standard Inframe Rebuild Kit IF4025072-4B

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.

• This rebuild kit is built to strict OEM specifications. Stricter than a dad with his daughter’s boyfriend!
• You will receive all new parts that are manufactured and assembled in an ISO 9001:2008 certified facility ensuring proper fitment and function. Plus, with all new parts, there’s no core charge. That’s money in your pocket!
• You will receive equal or better quality than the OE at a much lower price. You can’t beat that!
• When you purchase a rebuild kit from 4BTdiesel you are restoring your engine to good working condition, extending the life of your rig for the next generation to take over the family business.
• Beef up your engine with pistons that are CNC turned to precise tolerances. These will give you the consistency that is necessary for a good working engine.
• We all know that one guy that always has a puddle under his rig. It won’t be you with oil control rings designed with precise tangential tension for proper oil control.
• Make your engine tough as nails with connecting rod and main bearings that are crafted with tri-metal for durability. That’s impressive!
• Ever hear of the little engine that could? He is still running thanks to these piston pins that are hardened and tempered for improved strength and wear resistance.
• Let’s seal the deal! Since the correct materials are used, these gaskets have excellent performance in functionality and seal ability, keeping your fluids where they’re supposed to be.
• The sealing products in this kit are proudly made in the USA using 100% asbestos-free material. I think that speaks for itself.
