Cummins 4B Inframe Engine Rebuild Kit, New (IF38022484B)

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.

• Let’s make your engine tough as nails. Tri-metal connecting rods and main bearings are included to for long lasting strength and durability.
• Tired of being on the side of the road? Trust 4BTdiesel with a rebuild that restores your engine to great working condition and keeps it running for another million or more miles.
• Don’t settle for sub-par parts! We put the OE to shame with top-notch quality and consistency. This rebuild kit goes through a rigorous manufacturing and assembling process at an ISO 9001:2008 certified facility.
• Plus, our quality meets or exceeds the OE’s at a much lower price, giving you the value you deserve. But, the fact that all new parts are included and there is no core charge takes the cake.
• Let’s talk Pistons. You can rest assured the pistons included are CNC turned to precise tolerances, and are computer control machined to proper clearances. It doesn’t get much better than that!
• Want to keep your oil where it needs to be? The sealing products within this kit are proudly USA made and use 100% Asbestos-Free material. Additionally, the correct materials are used in the crafting of the gaskets ensuring exceptional performance in functionality and sealability.
• Piston pins are hardened and tempered for improved strength and wear resistance. Ever heard of the little engine that could? We bet he had these piston pins. 
• Leakage? Never heard of it, the gasket materials are composed of the OEM’s to give you leak free durability.
• Oil control rings are included and they are designed with precise tangential tension for proper oil control. You can’t beat that!
• You’ll get back up and running in no time since all parts are crafted to strict OEM specifications, giving you the best of fit and function.
