1.880 Exhaust Valve - 5.494 OAL 11/32

The Brodix 1.880 Exhaust Valve with 11/32 inch valve stem and 5.494 inch overall length is engineered for high-performance big block Chevy marine engines, particularly those running in demanding saltwater and freshwater boating environments. Built from stainless steel, this exhaust valve is designed to withstand the corrosive conditions and extreme thermal cycling that marine powerplants endure. For serious anglers and tournament boaters who depend on reliable, consistent engine performance—whether trolling offshore or running coastal flats—quality valve components are non-negotiable investments in engine longevity and dependability.

This exhaust valve features a 1.880 inch head diameter paired with an 11/32 inch stem diameter, precision-engineered geometry that optimizes flow characteristics and seating integrity under sustained high RPM operation. The stainless steel construction resists oxidation and corrosion better than conventional steel, critical for engines exposed to salt spray and moisture-rich marine atmospheres. At 5.494 inches overall length, the valve integrates seamlessly with standard big block Chevy cylinder head ports, maintaining factory-spec clearances and valve train geometry while delivering superior material durability and heat dissipation properties.

Boaters rebuilding or refreshing big block Chevy marine engines—whether small-block or performance-upgraded packages—will find this Brodix exhaust valve essential for compression integrity, combustion seal, and engine reliability. Installation requires precise valve seat machining and proper spring tensioning; work with experienced marine engine builders familiar with big block Chevy cylinder head specifications. Each valve is sold individually, allowing customization of your valve train configuration based on specific engine build goals and performance targets.
