Thumbnail Filmstrip of 6.4 Powerstroke Fuel Injector Sleeve SBI 240-1043 Images
Protect the precision of your fuel system and the longevity of your cylinder heads with the SBI Stainless-Steel Fuel Injector Sleeve (240-1043). In the Ford 6.4L Powerstroke, the injector sleeve (or "cup") acts as a vital thermal and physical barrier, isolating the fuel injector from the engine's coolant passages while providing a perfectly machined seat for the injector to seal. Because these sleeves are constantly exposed to extreme combustion temperatures and high-pressure coolant, original equipment units can eventually succumb to cavitation or fatigue. Upgrading to a high-grade stainless steel sleeve ensures superior resistance to corrosion and thermal cycling, preventing the "fuel-in-coolant" contamination that can lead to costly cooling system failures and engine overheating.
- High-Endurance Material: Constructed from premium Stainless Steel for enhanced durability and resistance to chemical corrosion from modern diesel fuels and coolants.
- Precision Engineering: Designed as an OE-Style Replacement that meets stringent industry standards for a perfect press-fit in Ford 6.4L Powerstroke injector bores.
- Sealing Integrity: Provides a flawless sealing interface between the injector and the head, ensuring consistent combustion pressure and preventing leaks.
- Professional Rebuild Ready: Ideal for replacement during routine cylinder head service or complete engine overhauls to ensure "like-new" performance.
- Peace of Mind: Sold as an individual component for targeted maintenance and backed by a 1-Year Limited Manufacturer Warranty.
Choosing the SBI 240-1043 is a proactive step toward "bulletproofing" your 6.4L Powerstroke. Since these tubes must be pressed into the head with precision, the use of stainless steel provides the structural rigidity needed to maintain a high-interference fit that won't shift under the intense vibrations of a working diesel. Replacing your injector sleeves during a head service is a hallmark of professional engine building—it eliminates a common failure point and guarantees that your high-pressure common rail injectors are seated in a pristine, reliable environment. Whether you're refreshing a fleet vehicle or building a high-performance tow rig, these SBI sleeves offer the industrial-grade reliability your Powerstroke demands.
