45-Degree High-Flow Cooling Solution

Optimize your cooling system geometry with the March Performance 45-Degree Thermostat Housing. Specifically engineered for GM LS-Series engines, this component provides the ideal angle for hose routing when a straight or 90-degree housing won't suffice. Crafted from high-strength aluminum and finished in a clear anodized coating, this housing is designed to perform under the most demanding conditions while maintaining a polished, professional appearance.

Key Features & Benefits

  • Design: 45-degree exit angle for versatile hose positioning.
  • Construction: Precision-machined billet aluminum for durability.
  • Finish: Clear anodized for long-term corrosion resistance.
  • Fitment: Designed for seamless integration with GM LS-Series engines.
  • Seal: Includes high-quality O-ring and mounting hardware.
  • Hose Size: Standard 1-1/2 inch ID hose barb.

The 45-degree angle is the perfect middle ground for custom radiator setups, allowing for smoother hose transitions and reduced stress on your cooling system components. By upgrading to this billet housing, you eliminate the common failure points of stock plastic or cast aluminum units. The precision machining ensures a perfect seal every time, preventing coolant leaks that can lead to engine overheating. Whether you are restoring a classic or building a modern performance machine, this housing provides the reliability and flow efficiency you need.
