Upgrade your 7.3L Powerstroke Diesel cooling system with the SWAG Performance Billet Thermostat Housing, engineered for diesel enthusiasts who demand reliability, performance, and style under the hood.
Built as a direct replacement for the weak and leak-prone OEM housing, the SWAG Performance unit is precision-machined from premium billet aluminum for unmatched strength and durability. Unlike stamped factory units that warp, corrode, and fail over time, our design delivers a much stronger base that resists leaks and thermal stress, keeping your engine running cool when it counts most.
