Granatelli Motor Sports Black Billet Thermostat Housing with 180-Degree Thermostat Jeep Trackhawk, RAM TRX, and Dodge Durango Hellcat
Engineered for superior cooling, unmatched durability, and seamless installation, this USA-made upgrade outperforms all competitors, making it the ultimate choice for enthusiasts seeking peak engine performance. Crafted from 6061-T6 billet aluminum, this thermostat housing eliminates the weaknesses of fragile OEM plastic units, delivering a 40% increase in coolant flow and a robust design that withstands extreme conditions. Paired with a high-flow 180-degree thermostat, it ensures optimal engine temperatures, enhancing horsepower, torque, and engine longevity for your Jeep Grand Cherokee Trackhawk, RAM TRX, or Dodge Durango SRT Hellcat.
Why Granatelli
- Cooling: The included 180-degree high-flow thermostat opens earlier than stock units, circulating coolant sooner to maintain ideal engine temperatures. This reduces heat soak, prevents overheating, and boosts performance during aggressive driving, towing, or track sessions.
- 40% Increased Coolant Flow: Flush-mount bolts eliminate the factory housing’s flow-restricting bridge, allowing a 40% increase in coolant flow for superior heat dissipation compared to OEM and other aftermarket options.
- Durability: Machined from 6061-T6 billet aluminum, this housing resists corrosion, heat, and pressure far better than plastic OEM units prone to cracking and coolant leaks, ensuring long-term reliability.
- Thermostat Life: By reducing head pressure on the thermostat spring, this design extends thermostat longevity, minimizing maintenance and protecting your engine from heat-related wear.
- Black Anodized Finish: The black anodized coating enhances durability while adding a professional, custom aesthetic to your engine bay, setting it apart from standard silver or natural-finish competitors.
- Sensor Integration: A 1/2" pipe thread port allows for optional temperature or pressure sensors, or a flush-mount pipe plug, offering customization not found in most aftermarket housings.
- Installation: Uses factory bolts for a seamless, leak-free fit with no gasket required, maintaining an OE look while simplifying installation with basic hand tools—no drilling or modifications needed.
- USA-Made: Designed and manufactured by Granatelli Motor Sports in California, this kit reflects decades of motorsport expertise, trusted by racers and performance builders worldwide.
