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.
- Restore and extend the life of your engine with a new Inframe Rebuild Kit that’s built to OEM specifications for proper fit and function within your engine.ย
- To ensure quality and consistency you can trust, your rebuild kit is manufactured and assembled in an ISO 9001:2008 certified facility. Why sacrifice quality if you don’t have to?ย
- Keep oil in it’s place and maintain proper oil controlย with oil control rings designed with precise tangential tension. You can’t beat that!ย
- Get the best of both worlds with pistons that are CNC turned to precise tolerances and use computer controlled machining to maintain proper clearances.
- That’s not all! Piston pins are hardened and tempered for improved strength and wear resistance to get you to another million miles.ย
- Don’t settle for sub-par parts! 4BTdiesel makes certain you receive equal or better quality compared to the OE, at a much lower price!
- Leakage? Not here. For leak free durability, correct gasket materials are used withย 100% asbestos-freeย American made sealing products.
- For sturdiness over time, rod and main bearings are constructed with tri-metal components.
- To top it off, your Inframe Rebuild kit will consist of brand new parts. Get the most of your money and don’t worry about a core charge.
