Product Details
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.
- You’ll get a brand new Rebuild Kit built to OEM specifications and has equal or better quality compared to the OEM. You can’t beat that!
- This Rebuild Kit is manufactured and assembled in an ISO 9001:2008 certified facility. Simply put, quality and consistency you can count on!
- You are not settling for sub-par parts when you buy from 4BTdiesel! Ourย OEM gasket materials are used throughout for leak free durability.
- The Oil Control Rings are designed with precise tangential tension for proper oil control. Plus, the Pistons are CNC turned to precise tolerances. In other words, you’ll getย optimal performance for your rig!
- Think you’re tough?! The Rod and Main Bearings in this rebuild kit are constructed of tri metal for durability. Also,ย the Piston Pins are hardened and tempered for improved strength and wear resistance.
- With 4BTdiesel you are getting top notch parts at a fraction of the cost of OE, leaving some coin in your pocket!
