Cummins 4B 3.9L, 6B 5.9L, 4B 4.5L Piston Cylinder Kit, New (3802032)

Think you know the truth about Piston 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 new Piston Kits. 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 Piston Kits, what’s left to want?
