Thumbnail Filmstrip of 5.9|6.7 Cummins Exhaust Valve Seat SBI SB1375E-2N Images
The SBI Exhaust Valve Seat SB1375E-2N is the ultimate solution for the high-heat environment of your Dodge Ram 5.9L or 6.7L Cummins diesel. In a diesel engine, the exhaust valve seat is the most thermally stressed component in the cylinder head, as it must withstand a constant barrage of scorching gases while providing a reliable sealing surface. Standard seats can soften and "recess" under extreme loads, leading to loss of compression and eventual engine failure. By upgrading to SBI’s "Star Series," you are installing a component specifically engineered to thrive in these brutal conditions, ensuring your engine retains its power and efficiency even during heavy towing or high-performance applications.
- Star Series Nickel-Based Alloy: Specifically formulated to maintain critical hardness levels at temperatures exceeding 1600°F, providing unparalleled resistance to thermal fatigue.
- Non-Magnetic Construction: The specialized nickel-based material is non-magnetic, offering unique metallurgical properties that reduce wear and increase the overall service life of the valve and seat.
- Individually Cast Design: Unlike generic inserts cut from tubes, these are individually cast to ensure superior grain structure, consistent material density, and optimal heat dissipation.
- Direct OEM-Style Replacement: Engineered to fit the precise architecture of the 5.9L and 6.7L Cummins cylinder heads, allowing for a professional-grade installation with factory-level geometry.
- Sold Individually: Allows for maximum flexibility, whether you are replacing a single damaged seat or performing a full performance-grade cylinder head overhaul.
Educationally, the choice of a nickel-based alloy is a game-changer for diesel longevity. As exhaust temperatures rise, standard cast iron or low-alloy seats begin to lose their structural integrity, but the SB1375E-2N remains stable, preventing the valve from "sinking" into the head. This stability is crucial for maintaining proper valvetrain clearance and preventing the loss of seal that can cause burnt valves. By choosing an individually cast, non-magnetic insert, you are investing in a component that facilitates superior material formation and heat transfer. Whether you’re maintaining a high-mileage work truck or building a high-boost 24-valve, these Star Series seats provide the thermal defense necessary to keep your Cummins running cooler and longer.
