Thumbnail Filmstrip of 7.3 Powerstroke New Cupless Cylinder Head With Heavy Duty Springs Powerstroke Products PP-7.3LH-HDVS Images
Upgrade your 7.3L Powerstroke with this high-quality new cupless cylinder head from Powerstroke Products. Built on a fresh casting with pressed-in valve seats, it comes fully assembled with heavy-duty 155 lb performance valve springs rated for up to 4,500 RPM. This is an excellent choice for daily drivers, work trucks, tow rigs, and mildly modified 7.3 Powerstrokes that need better reliability and valvetrain control.
Features:
- New casting – Not a remanufactured core; built from the ground up for consistent quality and fitment
- Pressed-in valve seats – Added durability for long-term performance
- 155 lb heavy-duty valve springs – Provides excellent control at higher RPMs and supports moderate performance modifications or heavy towing
- Cupless injector bore design – The biggest advantage: injector seating is machined directly into the head casting. No separate injector cups to crack, leak, or replace. This eliminates one of the most common and expensive failure points on the 7.3 Powerstroke.
- Fully assembled and ready to install (includes new valves, springs, retainers, and seals)
Traditional 7.3 heads use separate injector cups that are notorious for cracking and allowing fuel to mix with coolant (or vice versa). The cupless design removes that weak point entirely. If you want maximum reliability and never want to deal with injector cup replacement again, this head is the smart choice.
Note: These heads do not use traditional injector cups. They are not ideal if you specifically want the ability to easily swap cups in the future.
Sold individually. For best results on performance or high-mileage builds, pair with quality head gaskets and ARP head studs.
