Cummins 4B Standard Rebuild Kit

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.

• Don’t settle for sub-par parts. You’ll receive a brand new rebuild kit that is manufactured and assembled in an ISO 9001:2008 certified facility. This ensures top-notch quality and consistency.
• Plus, a new rebuild kit will not only restore your engine to optimal working condition but also increase its longevity.
• Think you’re tough? The tri-metal connecting rod and main bearings included sure are. These bad boys will help your rig stay up and running for another million miles. 
• Let 4BTdiesel help fortify your engine with piston pins hardened and tempered for improved strength and wear resistance.
• Computer controlled piston machining is used to maintain proper clearances, and the piston included is CNC turned to precise tolerances.
• Let’s talk savings. Quality will meet or exceed the OE’s at a much lower price. That means you’ll have more cash on hand. You can’t beat that! Additionally, the savings will continue because all new parts are included and there is no core charge! 
• Oil leakage? Won’t happen on our watch. The oil control rings included are designed specifically with precise
  tangential tension to keep the proper control of oil. Plus, the materials are on par or better than the OE’s giving you leak free durability. 
• These aren’t your Grandpa’s gaskets,correct materials are used making sure gaskets have maximum performance in functionality and seal ability. USA made? You got it! The sealing products are USA made and are composed of 100% asbestos-free material. 
• You won’t have to worry when it comes to fit or function. This kit is built to OEM specifications giving you the best of both.
