Product Details

Think you know the truth about Aftermarket Cylinder 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 Cylinder 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 Cylinder Kits.

  • Do you know where your parts come from? Now you do! You will receive a brand new cylinder kit that is manufactured and assembled in an ISO 9001:2015 certified facility. This ensures quality and consistency.
  • It can be hard trying to find the right parts but we can make the search easier. All 4BTdiesel parts are crafted to strict OEM specifications which gives you proper fit and function.
  • If you are looking for that extra power for your engine, you came to the right place. With an all new cylinder kit you will increase your engine performance performance while reducing oil consumption.
  • Are you and your engine in it for the long haul? A new kit will provide long lasting durability and improved fuel economy to help you go a million more miles. 
  • Give your bank account a break and shop with 4BTdiesel. Our parts have equal or better quality compared to the OE at a much lower price.
