305 Sprint Radiator Hose 1-1/2in x 1-3/4in

The 305 Sprint Radiator Hose 1-1/2in x 1-3/4in by FSR Racing is a specialized cooling system component designed for high-performance sprint car applications. This hose is essential for directing coolant flow between the engine block and radiator, particularly under the demanding conditions of racing. It is ideal for builders and mechanics looking to upgrade cooling systems on 305 small-block engines.

Featuring a tapered design that transitions from 1-1/2 inches to 1-3/4 inches, this radiator hose allows for seamless connections between differently sized ports without the need for adapters. The construction utilizes a high-temperature-rated rubber compound, specifically engineered to endure the intense heat cycles experienced during competitive racing. Additionally, the reinforced internal structure prevents collapse under vacuum conditions that can occur during engine operation.

Mechanics and engine builders restoring or upgrading 305 sprint car cooling systems will find this hose beneficial due to its compatibility with standard sprint car radiator plumbing. Its step-down configuration is designed to optimize space and performance, ensuring efficient hose routing that maintains full coolant flow while minimizing turbulence and pressure drop.
