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?ย
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 sellย Rebuild Kits with new parts, zero core charges, and a 6-month warranty to 50% off OEM prices.ย So, when it comes to your rebuild, what’s left to want?ย
Need a little extra proof? Let’s talk Rebuild Kits.
- Beef up your engine with aย brand newย rebuild kitย manufactured and assembled in an ISO 9001:2008 certified facility.ย Not only are you gettingย quality and consistencyย your rig needs, but since it is all brand new parts, there isย no core charge.ย Giving you more cash in your pocket!
- This rebuild kit is built toย OEM specifications,ย ensuring proper engineย fitment and function.ย Stricter than a dad with his daughter’s boyfriend!
- With this overhaul kit you will be restoring your engine toย good working order, extending the life.ย But you are also getting partsย equal or better qualityย than theย OE at a much lower price.ย You can’t beat that!
- No one likes a leaky rig.ย So, we use theย correct materialsย in our gaskets to ensure you haveย excellent performanceย inย functionality and sealability.
- At 4BTdiesel, we make sure you areย never getting sub-par parts!ย These pistons areย CNC turned to precise tolerances.
- Know you’ll be able to putย another million milesย on your diesel with piston pinsย hardened and tempered for improved strength and wear resistance.
